The post SciChart WPF v6.0.1 Released appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

Following the successful release of SciChart WPF v6, and the warm reception by our users for the massively improved performance, We were curious to see just what SciChart WPF v6 – The World’s Fastest WPF Chart was able to do … So just for fun, we created a tech demo which showcases SciChart drawing 10,000,000,000 (Ten Billion!!) data-points in a real-time, streaming, WPF Chart application.

The demo is part of our examples suite, but is capped to 1-Billion data-points. We modified this demo to draw 4, 8 Billion and 10 Billion points just to see what SciChart could do!

Rendering 10 Billion Data-points

The Limits of Technology

So what are the limits here? The limits we are pushing are honestly system RAM, and we start to hit some interesting operating system limits. For example:

• The maximum number of items in an array in .NET is limited by Int32.MaxValue: approximately 2.1bn elements in a single array is the .NET Framework max.
• The maximum size of an object in the managed heap is 2GB. For 32-bit floating-point values that caps your maximum array size to 536,000,000 items.
• So, to display 10 Billion data-points, we had to create and draw many series of 500M points.

10 Billion points of floating point data requires 10Bn * 4-bytes * 2 (X,Y values) = 80GBytes of memory as well, and the best computer we could find in the SciChart office was a Macbook Pro with 64GB Ram. So, we had to rely on SciChart’s optimised swap-disk and memory compression algorithms, as well as our proprietary C++ / cross-platform 2D/3D graphics engine named Visual Xccelerator to render this quite frankly, massive, big-data set.

How on earth did we achieve this technical feat?

In the article, SciChart WPF v6 ‘Xccelerated Edition’ Up to 100x (10,000%) Faster WPF Charts! we outlined why as a result of user-feedback, we chose to improve the performance of our already fast WPF Chart controls.

Next, we talk about the in-depth testing that we performed to measure the speed of our WPF Charts. Finally we talk about the technical accomplishments showing the performance improvements across chart types.

Have a read of the article to learn how SciChart beats all known competitors in WPF Charting performance.

The World’s Fastest WPF Chart Library

Without doubt, we are certain that SciChart WPF brings you the World’s Fastest WPF Chart control! Not only can you render huge data-sets but our charts are also lightweight and performant, giving you:

• Lower CPU usage and memory usage than all known competitors.
• Higher frame-rate (FPS) than all known competitors, including on lower-end hardware.
• Full GPU acceleration, taking advantage of the latest and future advancements from nVidia, Radeon.
• Full software fallback, for Virtual Machines without GPU, Citrix Gateway and Remote desktop
• Parallelisation, taking advantage of the latest advancements from CPU Manufacturers Intel & AMD.

Not only that, but our WPF Charts are fast & flexible, support MVVM & XAML throughout, are award winning and are rated Best by hundreds of users. When you purchase SciChart WPF you are buying an incredibly complex piece of technical equipment with millions of lines of code, made simple & easy to use by our talented tech & engineering team.

The post SciChart WPF v6.0.2 Released! appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

We are pleased to announce that the SciChart WPF v6.1, build 13075 has now been released! This update includes a number of bug fixes reported by users since the version 6.0.2 release and a new feature. This release is a drop-in replacement for 6.x and it is recommended for all users to update.

We respond to any issues or bugs quickly and are proud to give you a quick turnaround. During the process of resolving these issues, we have been publishing to our Nightly Build feed continuously.

What’s new in v6.1.0?

New features

Preloading SciChart native libraries and async load licensing before a SciChartSurface is shown

Some customers have reported slow initial startup time with SciChart and asked for a way to do this initialization earlier in the application, e.g. when a splash-screen is shown.

We’ve published a sample on Github showing how to do async library loading with SciChart WPF v6.1 using two two static methods.

• SciChart2DInitializer.LoadLibrariesAndLicenseAsync
• SciChart2D3DInitializer.LoadLibrariesAndLicenseAsync

Usage

In the Github sample:

1. App.xaml.cs overrides OnStartup and calls SciChart2D3DInitializer.LoadLibrariesAndLicenseAsync
2. MainWindow.xaml initially shows some loading content, no SciChartSurfaces are shown initially
3. MainWindow.Loaded event handler awaits SciChart2D3DInitializer.Awaiter before swapping the content for SciChartSurfaces

In essence, it doesn’t matter how you do it, just make sure you await the result of SciChart2D3DInitializer.LoadLibrariesAndLicenseAsync or SciChart2D3DInitializer.Awaiter (it’s the same task) before any SciChartSurface is called.

This method is fully thread safe, it can be called as many times as you like, but will apply license and init only once.

Note

• SciChart2D3DInitializer (available in the SciChart 3D package) initializes both 2D & 3D libraries.
• SciChart2DInitializer (available in the SciChart 2D Package) initializes just 2D

Exceptions fixed

• SC-5315 Fixed AccessViolationException when changing MeshColorPalette on SurfaceMesh3DViewModel
• SC-5307 HlcDataSeries index out of range exception fixed for NaN low or high values
• SC-5314 Fixed NullReferenceException in BaseRenderableSeriesSceneEntity3D.set_IsVisible
• SC-5302 Fixed unhandled exception in Dashboard Style Chart example
• SC-5290 Fixed a crash with Tooltip popups

Visual Errors fixed

• SC-5301 Improved the appearance of lines in the Visual Xccelerator engine by improving the anti-aliasing algorithm. This reduces the appearance of Jagged lines when dark series are on a light background.
• SC-5112 Fixed incorrect colors of Candlesticks when YAxis is flipped
• SC-5319 Fixed IsDigitalLine bug with VisualXcceleratorEngine and DataTemplate
• SC-5316 Fixed FreeSurfaceRenderableSeries3D appears semi-transparent if MeshColorPalette is not set
• SC-5279 Fixed Some visual anomalies on Band Series with Visual Xccelerator engine
• SC-5311 Fixed cropped example titles, changed data template for example items
• SC-5292 Fixed Incorrect Scatter Series appearance when custom PointMarker is used
• SC-5273 Fixed Dashed line inconsistencies between Band and Line, DigitalLine series in SciChart WPF v6 with Visual Xccelerator engine
• SC-5264 Fixed Candlestick Width is changing when panning in X-direction when X-axis is DiscontinuousDateTimeAxis

Other bugs fixed

• SC-5322 Added missing view-model for the FreeSurfaceRenderableSeries3D
• SC-5289 Fixed xyzDataSeries3D.Append() method causing issues in 3D Chart
• SC-5309 Fixed default binding for SciChartScrollbar.SelectedRange when the axis is changed; overriding of custom user binding for SciChartScrollbar.SelectedRange and Vertical SciChartScrollbar scrolls in the opposite direction when clicking outside the scroller
• SC-5303 Fixed RenderableSeries update delay after zooming out the SciChartSurface
• SC-5313 Fixed RenderableSeries ignore opacity on the Fill brush when VisualXcceleratorEngine.IsEnabled=True
• SC-5300 Fixed MouseEvents stick to the last window
• SC-5306 Fixed “cannot find source for binding with reference” warnings when FastImpulseRenderableSeries is used
• SC-5295 Fixed IsVisible property doesn’t work for PointLineRenderableSeries3D and ImpulseRenderableSeries3D
• SC-5294 Fixed Histograms disappear in MarketProfileTradingExample when VXEngine is enabled
• SC-5258 Fixed the Fill property change doesn’t work when VXEngine.IsEnabled=True
• SC-5257 Fixed FastVolumeCandlestickRenderableSeriesForMvvm shows gaps incorrectly
• SC-5229 Fixed TooltipModifier Tooltips do not appear on a vertical Scatter chart

The post Our Commitment to Excellence during Covid-19 appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

About a year ago we announced that we would begin research into SciChart.js – a Fast, Realtime 2D & 3D Chart Component for HTML5 / Javascript apps. Today we have some more results to share with you and an update on our progress!

SciChart.js development is well underway within SciChart. Without giving too many technical details away, we have a cross-platform graphics engine which enables our extremely fast 2D & 3D charts on Windows, Mobile. This has now been cross-compiled to the web entirely and we are working on the top level API.

See below to see a short video of a stack chart rendering Line Series, multiple X & Y Axis, and panning behaviour on mouse down. Overall frame rate is very high, up to 60 FPS, and we anticipate the performance of SciChart.js to be very high as we develop the charts for real-time javascript applications.

SciChart.js will have the API you are familiar with when using SciChart. Our existing WPF, iOS & Android charts have the following concepts for chart parts:

• SciChartSurface: the top level chart container
• RenderableSeries: responsible for drawing Line, Mountain, Column, Scatter, Candlestick chart series
• DataSeries: a data-structure which holds your data. Supports dynamic update (Append, Insert, Update, Remove) for real-time charts.
• ChartModifiers: behaviours which are tagged onto the chart – zooming, panning, tooltips etc…

For example, declaring a chart like will be possible in TypeScript or Javascript using code like this:

// Create the SciChartSurface targeting DOM id canvas-id 
const sciChartSurface = new SciChartSurface('canvas-id');

// Create DataSeries, using Append, Insert, Update, Delete that you are familiar with
const data = new XyDataSeries();
data.append([0,1,2,3,4], [10,11,12,13,14]);

// Add RenderableSeries for lines, candlestick charts, scatter charts etc...
sciChartSurface.renderableSeries.add(new FastLineRenderableSeries({ dataSeries: data } ));

// Add and configure X & Y axis
sciChartSurface.xAxes.add(new NumericAxis());
sciChartSurface.yAxes.add(new NumericAxis());

// Add zooming, panning or tooltip behaviour 
sciChartSurface.chartModifiers.add(new ZoomPanModifier());
sciChartSurface.chartModifiers.add(new TooltipModifier());

…which would result in a chart with single X,Y axis, a line series with 5 data-points and the Zoom pan and Tooltip behaviours added to the chart.

We’re also aiming to make SciChart available to vanilla JS applications as well as popular frameworks such as React, Vue.js etc…

Why SciChart.js?

Why build SciChart.js? Javascript, Typescript and React chart libraries are ten a penny right?

Well, there’s a few reasons why we wanted to build SciChart for javascript applications, and why SciChart will be a great choice for your future web projects.

Realtime Performance

We’ve always provided the best-in-class for performance, and SciChart.js will be no different. Built on our blazing fast 2D/3D engine Visual Xccelerator, SciChart.js will be able to render millions of data-points in realtime in Javascript applications.

Excellent, Best-in-class API

Our API is rated the best for charts on Windows and Mobile platforms, because it is easy to use, powerful, flexible and provides deep customisation. SciChart.js will be no exception and we are porting our award-winning API to Typescript/Javascript so you can have the same excellent best experience on the web.

2D and 3D Charts

SciChart provides not only 2D Charts, but also hardware-accelerated 3D Charts. Need a WebGL powered 3D Chart component for scientific or data-intensive applications? SciChart.js will be able to do that.

Suitable for Demanding Applications

SciChart is geared towards demanding applications such as Financial & trading, Scientific & Medical, Engineering as well as complex enteprise applications which need the best possible visualisation.

Our software is used around the world by companies ranging from Automotive to F1, Banking & Trading, Oil & Gas to Cancer Research, Medical applications to fitness tracker apps. Across sectors SciChart makes impossible projects possible, and we believe web will be no different…

The post SciChart WPF v6.1.1.13136 Released! appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

In these unprecedented and unusual times we are pleased to announce to you that we are not only still operational, but also delivering new features & updates to our users and today have a release of SciChart Mobile SDK v3.1!

This release brings you some long-standing features requested by our users via the Feature Request portal, and some showcase demos of how to use SciChart iOS, Android or Xamarin in medical or scientific context.

What’s New?

A full list of what’s new can be found below.

iOS/Android Vital Signs ECG/EKG demo

Formerly part of the SciChart showcase, we have created and updated our Vital Signs (ECG/EKG) demo showing how to use SciChart’s iOS, Android or Xamarin charts in a medical context.

Four channels of data are simulated, showing how SciChart iOS/Android can be used to draw real-time, high performance ECG/EKG charts & graphs to monitor blood pressure, SPO2 blood oxygen, and volumetric flow enabling you to create medical apps using an iPad or iPhone device.

SciChart helps you shortcut development of medical applications by providing rich, real-time, high performance & reliable iOS charts for use in Vital-signs monitors, blood pressure monitors, Electro-Cardiogram, medical Ventillators, patient monitors, digital stethoscopes, medical testing devices and more.

If you are creating an app that needs to visualize body temperature, pulse rate, respiration rate, blood pressure, or similar, choose SciChart to shortcut your development time & get to market faster with our well-tested, reliable
iOS/Android/Xamarin Chart library.

iOS/Android Audio, Radio Frequency & Spectrum Analyzer demo

Another demo we’ve created is the Audio/Radio Frequency Spectrum Analyzer demo.

The Audio analyzer demo showcases how to use SciChart iOS (android) charts in a scientific context. Download the examples and enable your microphone to see this demo at work.

In this example we listen to the microphone on your iOS/Android device and create a waveform of the sound recorded in the top chart. This chart has 500,000 data-points drawn in real-time on our High Performance charts. The example application then performs a Fourier Transform, creating a spectral / frequency analysis of the audio waveform and plots in the lower left chart. Finally, the histogram of the fourier transform, known as a spectrogram, is plotted in a SciChart iOS Heatmap control in the bottom right of the example.

If you are creating an app that needs to visualize scientific data from data-aquisition devices, audio spectra, or visualize radio frequency or spectrial analysis choose SciChart to shortcut your development time & get to market faster with our well-tested, reliable iOS/Android Chart library.

iOS/Android Spline Line Series

SciChart iOS & Android now features a native spline-line (smoothed line) series. Given a few number of points, our customers wanted to see smoother charts out of the box with spline smoothing / bezier interpolation between data-points.

SciChart Mobile SDK v3.1 features a spline line series which provides aesthetically pleasing, high performance smoothed line charts for iOS or Android apps.

Performance is excellent thanks to our intelligent, dynamic smoothing, and interactive frame rates with point counts in the 100,000 or even millions of data-points are still possible.

iOS/Android Spline Mountain Series

SciChart Mobile SDK v3.1 now features a spline mountain or area series which provides aesthetically pleasing, high performance smoothed mountain/area charts for iOS or Android apps.

Again, performance is excellent thanks to our dynamic smoothing and this chart type allows interactive frame-rates into the hundreds of thousands of points.

iOS/Android Spline Band Series

We’ve also added a spline band series natively which provides aesthetically pleasing, high performance smoothed band / high-low fill charts for iOS or Android apps.

New Rounded-Column Custom Series Example

Column charts with rounded top/bottom have been requested via our Feature-request system. We haven’t build this feature natively but what we’ve done is used it as an example to showcase our powerful Custom Series API, which allows you to create any series type using a fast drawing context.

Other New Features:

• SCIOS-944 – added support for placing Legend outside of SCIChartSurface
• SCIOS-964 – added rollover marker color customization into the customization rollover modifier example
• SCIOS-937 – added support for changing (add, remove, etc) the DataSeries from the background thread

But wait, there’s more!

Since v3.0 of SciChart for Mobile, we have fixed a number of bugs & issues reported to us by customers over the past 3 months. These are listed below.

SciChart for Mac OSX in Progress

We announced recently on our Twitter and Linked-In page that we are making steady progress toward making SciChart available on Mac OSX. The codebase and API will be shared with iOS, and we will support Objective-C, Swift apps built for MacOS desktop computers.

More info on this coming soon. Subscribe to our newsletter by registering with SciChart to be notified when we release!

The post SciChart Mobile SDK v3.1 Released! appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

We are pleased to announce that the SciChart WPF v6.2.0, build 13254 has now been released! This update includes a number of bug fixes reported by users since version 6.1.1. This release is a drop-in replacement for 6.x and it is recommended for all users to update.

What’s New in SciChart v6.2.0?

1. Addressed the Startup time of SciChart WPF.

Version 6.2.0 will now be up to 28x faster to initialize and show the first chart than v6.1.x. This improvement will be seen immediately and no changes to your code are required.

The time to initialise the first chart was due to initialisation of native libraries, licensing and the 3D engine. This has been significantly streamlined and

2. Addressed compatibility with older GPUs and multi-GPU PCs.

We’ve introduced a compatibility check on engine startup, and for multi-GPU PCs, SciChart will now choose the best available GPU. This solves a lot of problems and will improve performance on many of our users computers. Check the Visual Studio Output window after startup as we now log the compatibility check there!

We have identified Intel HD 4000 Series GPUs as having not enough Video RAM (VRAM) or features to correctly use SciChart’s Visual Xccelerator Engine in DirectX11 mode. We have added a check to downgrade to DirectX9 mode which uses less VRAM, or to choose a better GPU where one is available. This was a huge piece of work by our team which involved testing on multiple combinations of graphics hardware to ensure maximum stability and performance on end-user computers.

We have published a KB article on minimum requirements for SciChart Visual Xccelerator engine and some troubleshooting tips.

3. Improved the placement of labels in Perspective and Orthogonal 3D Charts

Label Placement has now been improved so that labels no longer overlap. This was a feature-request on our feedback portal and we’re pleased to announce its been delivered!

4. Created a Vital Signs Monitor demo

We’ve created a Vital Signs Monitor demo for SciChart WPF, to mirror the demo we have created for our iOS & Android charts. This can be seen in the short video below.

Bug Fixes and Minor Improvements

• SC-5376 Zooming In stops at some zoom level in SciChart v6.1.1.13117 and newer

The post SciChart WPF v6.2.0.13254 Released! appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

Hello everyone!

I wanted to give you a roadmap progress update as to what we are building, and give you some possible release dates for exciting enhancements to the SciChart product lineup.

2020 has been so far an absolutely crazy year … I’m sure many people have experienced disruption, crisis and some may even have lost loved ones, and we are no exceptions. However, near the start of the year we made the concerted decision to batten down the hatches and ride out the storms that the world is facing. As a result, we turned our attention to R&D, as these storms will pass, and when they do, we wanted to have new features, products and enhancements ready to go for our customer base.

I’d like to give you a short update on what we are developing now, and some progress at this mid-point through the year.

SciChart.js Javascript 2D/3D Charts Update

SciChart.js is a Fast Real-time Javascript 2D/3D Chart component. We launched our 3D engine earlier in the year on our Windows platform – known as Visual Xccelerator, it speeded our WPF Charts (Windows) by 10-100x resulting in insane performance such as our 10 Billion Datapoint tech demo. Using cutting-edge technology, we are the first in the world to develop an in-house, lightweight, cross-platform 3D graphics (game) engine and cross-compile it to all platforms including Windows, iOS, Android, MacOSX and now the web – with WebAssembly and WebGL.

WebAssembly represents a step-change for browser applications, as far from using only Javascript, which can be a performance bottleneck for critical sections of code, we are able to re-use our extensive C++ codebase and compile to WebAssembly (wasm) and use this in Javascript applications. SciChart.js will represent the absolute cutting-edge in Javascript 2D/3D charting, as no other chart library vendors in the world are currently developing the kinds of innovations that we are.

You can watch the video below to see our progress so far and how we’re coming along with this exciting new platform.

Our progress to date includes:

• 2D Javascript Chart types such as Line, Mountain/Area, Column, Scatter, Candlestick, Ohlc and Heatmap charts
• 3D Javascript Chart types such as Javascript 3D Bubble charts, 3D Scatter charts, point-clouds and Javascript Surface Mesh / Surface Plot
• Simple tooltips and legends
• Zooming, panning
• Linking multiple charts
• Basic annotations including line, box, text and custom annotations
• Theming including 2 themes (light and dark) out of the box
• Full hardware acceleration allowing millions of data-points to be drawn
• GPU Shader effects for enhanced visuals: glow, shadow, gradient brush

You can learn more about our progress and sign-up for newsletters over at the NEW SciChart Blog.

We’re making steady progress here and aiming to have something to release to our user base as soon as possible. Obviously, we have to make sure it’s a quality product and not something half-thought out so until we have something that we don’t think is going to change much we will wait.

SciChart for Mac OSX Progress Update

Another platform we’ve been building for is Mac OSX Desktop. Our Fast, Native iOS chart library is written in Objective-C and Swift, and allows you to create big-data, real-time data visualisations on iPhone and iPad devices. However, a feature request we are often asked about is MacOS.

90% of the code is portable immediately, no change, however it’s that last 10% that needs work. The zooming, panning interaction on an iPhone is via touchscreen whereas on a Mac it’s mouse or touchpad gestures. Annotations or labels which are drawn with UIView on iOS are not portable to MacOS. So we’ve been refactoring and working steadily and aim to bring you something soon.

When go-live, the SciChart Mac OSX platform will bring you fast, hardware-accelerated 2D/3D charts on the Mac desktop platform and will be available in the Bundle 2D, Bundle SDK and Bundle SDK Enterprise packages.

SciChart for Xamarin Forms

With our iOS/Android charts v3 released at the start of this year, bringing you hardware accelerated 2D & 3D charts to the iOS & Android platforms, we have turned our attentions on how best to expand the reach of SciChart and enable our users to build applications in different kinds of frameworks.

One framework which gets requested a lot is Xamarin Forms. At the moment we support Xamarin.iOS, Xamarin.Android which allows you to create Xamarin applications with SciChart. However a true Xamarin Forms wrapper (allowing write-once run anywhere) is missing from the SciChart product lineup.

We’ve made some progress in this area by writing a wrapper generator around our Xamarin.iOS/Android chart libraries. This generates the necessary Custom Renderers or Views and XAML API allowing you to include SciChart in Xamarin Forms applications, with familiar XAML based code like this:

Roadmaps and Release Timeline

We don’t typically like to give you a release date before things are ready, as there is often work to be done polishing code or making something production-ready long after it looks or feels finished.

Right now SciChart for Javascript, Mac OSX and Xamarin Forms are all making great progress, what we’re aiming for is Q3/Q4 release, although previews or some platforms may be sooner than that. If you are interested to receive notifications or updates then you can sign-up to our SciChart.js newsletter below, or just watch our social media pages such as LinkedIn, Twitter and Facebook as all announcements go there.

Finally if you’d like to speak to us to talk about your requirements or get more in-depth information, then contact-us! We’re always happy to hear from our customers & prospects to hear how we can better serve you.

Andrew

The post SciChart.js – Javascript 2D/3D Charts, Mac OSX, Xamarin Forms making steady progress appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

We are pleased to announce that the SciChart WPF v6.2.1, build 13303 has now been released! This update includes a number of bug fixes and minor enhancements requested by users since version 6.2.x. This release is a drop-in replacement for 6.x and it is recommended for all users to update.

What’s New in SciChart v6.2.1?

New Examples & Demos

Added the Lidar Demo to the Examples Suite. We created a blog post over at blog.scichart.com to show how to load Lidar data from the UK Defra Survey into SciChart, and visualize as a point-cloud and contour map. This example is now available in the SciChart WPF Examples Suite.

We also added a Webinar titled Algo Trading with SciChart WPF. We built an in-house Algorithmic Trading framework which lets you connect to a Crypto exchange (Bitmex, Binance) and execute algorithmic trades, as well as perform tick-by-tick backtests of your trading strategies, all visualised with SciChart WPF. 

If you’d like to know how SciChart can be used in the most demanding markets, with complex data-visualization (buy/sell markers on chart, multi-pane charts, different scaling per series, different indicator or filters on a chart, custom interaction behaviours) then take a look. 

IMPORTANT ISSUES FIXED in 6.2.1

The following issues are considered critical and we recommend customers update to avoid them from impacting your applications or development work.

• Fixed an issue where users of Multi-GPU PCs incorrectly dropped down to software rendering when auto-detecting GPU support for our DirectX Visual Xccelerator Engine.
• SC-5484 Fixed an issue where some customers could not activate a paid SciChart WPF License. This required an update in SciChart WPF as well as the Licensing Wizard.
• SC-5485 Fixed a bug where EnableImpossibleMode is True and the first two data-points have the same X-value results in hang & infinite loop.
• SC-5480 Fixed a bug where EnableImpossibleMode is True and chart has a few datapoints results in chart not updating
• Made VisualXcceleratorEngine.DowngradeWithoutException true by default. Ensure IsEnabledChanged processed after other dependency properties. This resolves issues where on some computers a compatibility exception is thrown.
• SC-5463 Fixed memory leak when AnnotationBinding is used and bound ObservableCollection changes reference
• SC-5463 improved fix for ‘MVVM Annotations memory leak’ by using CollectionChangedEventManager weak events
• SC-5465 Fixed the issue when RadarSurface would throw and exception when axes collection was bound
• SC-5458 Fixed ArgumentOutOfRangeException when deselecting RenderableSeriesViewModel
• Fixed LinearTrend and PolynomialTrend Filters are crashing when data in unsorted

Minor Issues fixed in 6.2.1

• SC-5440 Fixed incorrect rendering of SurfaceMesh2D when VisibleRange is set manually
• SC-5471 TooltipModifier3D stops working after SurfaceMeshRenderableSeries3D change
• SC-5463 Ensure VerticalSliceModifier.VerticalLines are created and updated when VerticalLinesBinding MVVM API is used.
• SC3D-488 Last point in Scatter3D series doesn’t obey Metadata color
• Fixed showing getting-started page whenever the Visual Studio Package Manager Console window was opened after installing SciChart from NuGet.

Where to Get SciChart WPF? 

SciChart WPF v6.2.1 is available by:

• Downloading from our scichart.com/downloads page.
• Using Install-Package or Update-Package from NuGet.

The post SciChart WPF v6.2.1.13304 Released! appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

As of August 3rd, 2020 we are going to change the retention policy of Cocoapods nightly build.  Please read on to secure your previously integrated SciChart packages and set up future feeds correctly into your build system.

SciChart iOS is available via CocoaPods. We provide public Podspecs so that you can integrate SciChart with minimum effort, either pinning to a specific version or always getting the latest stable release.

Learn how to integrate SciChart Libraries: SciChart iOS documentation.

If you’re new to CocoaPods, please see CocoaPods Getting Started guide.

Why the change in Package Retention?

Over the years we have built up quite a library of nightly builds and official releases for versions 2 and 3 of SciChart iOS. Instead of keeping these all together in one feed, we are working to put it all in order. We are organizing our feeds so that there is a feed for official releases and another one for the nightly builds. This is to help our customers to use the version they want and keep it well organized.

Nightly builds:

• Important: From the August 3rd, 2020 onward, all the nightly builds for version 2 will be removed. Please secure your builds if needed before the change.
• Nightly builds for version 3 and onwards will be kept at https://github.com/ABTSoftware/PodSpecs-Nightly.
• We encourage our users to use official release builds. 

Official releases:

• Official releases will be stored at https://github.com/ABTSoftware/PodSpecs,
• Official releases, including official releases of versions prior to version 3 will be kept indefinitely.

If you are using a nightly build we recommend using the latest (higher) official release as soon as possible. A list of official releases version numbers can be found at www.scichart.com/downloads in the right-hand column, please see below:

If you have any questions about how to ensure that your SciChart integration is seamless, please just contact us at support [at] scichart.com.

We are continuing to develop & support SciChart iOS and have some exciting new releases due soon. More to be announced in the near future!

Best regards,
[SciChart Support]

The post Your feedback needed. Video Courses for SciChart! appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

We are pleased to announce that the SciChart iOS and Android v3.1.1, has now been released!  There is a large number of improvements and bug fixes made in SciChart iOS and Android v3.1.1. It is recommended for all users of SciChart to update to the latest version! Please see more information below.

What’s New?

A full list of what’s new can be found below.

iOS/Android LIDAR Demo Example

We ported the LiDAR / GIS Point-cloud and contour topology dataset into our iOS and Android demo app, which resulted in a visualization of a 3D point cloud with a color map.

LiDAR data can be collected from a variety of sources: UAV drones (Unmanned Aerial Vehicles), self-driving cars, geological survey tools and more.

It can be used in a variety of scenarios: anything from defense/tactical operations to geological surveys such as energy/mining, geospatial analysis, civil engineering, construction, and more.

The source code for the iOS and Android demo is found at our Github repository under SciChart.iOS.Examples and SciChart.Android.Examples correspondingly.

iOS/ Android Sparklines chart example

We have added this example to respond to our customers’ questions about how to use SciChartSurface within RecyclerView.

You can find the source code to this example in our SciChart.iOS.Examples and SciChart.Android.Examples.

Bug Fixes and other improvements:

• SCIOS-1010: fixed column drawing with StrokePaletteProvider
• SCIOS-1007: fixed drawing dash lines in drawable behaviours
• SCIOS-1008: fixed usage of ISCIStrokePaint methods to draw drawable behaviours and point markers
• SC_DROID-778: fixed infinite loop in bezier curve interpolator when data is unsorted in x-direction
• SCIOS-1006: fixed AxisMarker and AxisLabel annotation has the incorrect position and dragging in VerticallyStackedYAxes example
• SC_DROID-776: fixed resizing annotations with restriction for resizing direction for iOS and Android
• SC_DROID-776: changed implementation of ResizingAction to resize annotations relative to the position of resizing grip instead of touchpoint; changed resizing indices for annotation to encode what properties were used to get positions as well as added method for getting resizing grip position based on index
• SCIOS-1002: fixed checking if coordinates are sorted
• SC_DROID-612: fixed incorrect hit test results if xAxis has flipped coordinates – added isCoordinatesSortedAscending flag for render pass data for iOS and Android
• SCIOS-1001: Memory leaks in SCIRenderableSeriesBase strokeStyleProperty and SCIProjectionCollection
• Fixed crash of spline series in iOS when they are only one point in data series; removed throwing of exception in Android in the same case
• Fixed axis labels reversed drawing on old iOS devices
• SCIOS-999: fixed wrong indexes calculation for tooltips
• Fixed exception when trying to animate series which isn’t attached to the chart
• Fixed dataPointWidth changing in ErrorBarsChart example
• SC_DROID-768: fixed crash on C++ side if disable drawing on 3D axis
• SCIOS-991: fixed not drawing SCIColumnRenderableSeries3D
• SCIOS-986: fixed the set args.isInSourceBound – so it is the same as in SciChart Android
• SC_DROID-764: refactored ISuspendable and UpdateSuspender to remove static Map with ISuspendables which could lead to memory leak chart as well as added disposing of cached xAxis and yAxis when detaching series from chart.
• SC_DROID-763: fixed incorrect calculations of zIndex in NearestUniformHeatmapPointProvider caused by using incorrect startX/startY value
• SCIOS-978: fixed Surface3d doesn’t unsuspend
• SCIOS-982: Fixed drawing custom annotations over axes.
• SC_DROID-762: fixed missing dashed lines which occurred if there were no AA lines rendered before
• SCIOS-980: fixed annotation label background missing if the placement is not axis
• SCIOS-976 and SC_DROID-757: modified culling algorithm to correctly handle default culling priority (-1) when ticks aren’t combined into groups; added protected methods to override axis rendering without creation custom renderers and fixed missing renderable series layer when rendering grid lines for iOS and Android

[SciChart Team]

The post SciChart Mobile SDK v3.1.1 Released! appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

Let’s get started with SciChart iOS and macOS!

Quickest of the Quick Start Guides

Ok so you’ve downloaded and unzipped the SciChart iOS and macOS v4 SDK. Great! Now what?

Check out this Quickest of the QuickStart Guide below which shows you how to open the Examples Suite, work through the tutorials and see what SciChart can do.

1. Starting a SciChart iOS and /or macOS Trial

In previous versions of SciChart iOS, you could download the framework from Cocoapods or our website and it would ‘just work’ for 30 days. With the release of SciChart iOS v3 we have introduced a new cross-platform licensing mechanism which is common to all our platforms.

1. Donwload the Licensing Wizard

To get started, download and install the SciChart Cross Platform Licensing Wizard to your Mac Desktop.

Download Licensing Wizard Mac

2. Log in

Next log in using your SciChart.com username and password (Create one).

3. Start a Trial

Click ‘Start Trial’ on the Trials page for iOS and or macOS.

4. Apply a trial Key

Apply the trial to your application by viewing the KeyCode on the Licensing Wizard. Be careful and use iOS one for iOS trial and macOS one for Mac.

The KeyCode must be set in your app once, and once only before any SciChartSurface instance is shown. Do this by calling the static SciChartSurface.SetRuntimeLicenseKey() method in AppDelegate.

Code samples below:

• Swift
• Objective-C
• Xamarin.iOS

//
//  AppDelegate.swift
//  SciChartSwiftDemo
//
 
import UIKit
import SciChart

@UIApplicationMain

class SCSAppDelegate: UIResponder, UIApplicationDelegate {

 var window: UIWindow?

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        // Note! This is just an example. 
        // The real License KeyCode is found by following steps above
        SCIChartSurface.setRuntimeLicenseKey("YOUR_KEYCODE")
 
        return true
 }

}

//
//  AppDelegate.m
//  SciChartDemo
//
 
#import "AppDelegate.h"
#import "SCDConstants.h"
 
// NOTE: Import SciChart.h 
#import <SciChart/SciChart.h> 
 
@interface AppDelegate ()
 
@end
 
@implementation AppDelegate
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
     
    // Note! This is just an example. 
    // The real License KeyCode is found by following steps above
    [SCIChartSurface setRuntimeLicenseKey:@"YOUR_KEYCODE"];
     
    //...    
    return YES;
}
 
@end

using Foundation;
using UIKit;
using SciChart;

namespace XamarinTestingLicensing
{
    // The UIApplicationDelegate for the application. This class is responsible for launching the
    // User Interface of the application, as well as listening (and optionally responding) to application events from iOS.
    [Register("AppDelegate")]
    public class AppDelegate : UIApplicationDelegate
    {
        // class-level declarations

        public override UIWindow Window
        {
            get;
            set;
        }

        public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
        {
            // Override point for customization after application launch.
            // If not required for your application you can safely delete this method
 
            SciChart.iOS.Charting.SCIChartSurface.SetRuntimeLicenseKey("YOUR_KEYCODE");

            return true;
        }
    }
}

Take a moment to start a trial now, so that you can get working as soon as possible.

Note, if you have purchased a paid license, then head over to Licensing SciChart iOS&macOS to learn how to activate and use it.

5. Great, But I have a Question about ..

We believe you will not find a better-supported iOS & macOS Chart Library than SciChart!

The post Getting Started with SCICHART iOS v3+ and macOS v4 appeared first on Fast, Native Chart Controls for WPF, iOS, Android and Xamarin.

In order to license SciChart iOS v3 and later / macOS v4 and unlock all its features, there is a simple procedure that must be followed. Without this you won’t be able to compile and debug applications built with SciChart iOS&macOS. Licenses are unique to all SciChart products, so licenses for other products cannot be used for SciChart iOS or Scichart macOS Charts and vice versa. If purchased individually SciChart iOS is a separate license form SciCHart macOS!

Please be aware before starting usage of the SciChart software constitutes acceptance of the licensing terms & conditions. SciChart is licensed per-developer with a royalty-free redistribution rights for your applications. A helpful licensing FAQ can be found here.

If you wish to purchase a paid SciChart license, you can do so at the store.scichart.com. Likewise, you can download the framework at our scichart.com/downloads page.

Instructions for starting iOS Chart or macOS Trials

In SciChart iOS v3 and later and macOS v4, trial licenses can be fetched with the cross platform licensing wizard. Trial licenses and technical support are tied to a SciChart account, so if you don’t have one, then head over to scichart.com/login and create an account now.

Download the licensing wizard from here and install on your Mac desktop.

Download Windows Download Mac

Once installed, and you have logged in with scichart.com account, you can start a trial in your chosen platform as follows:

Apply the trial to your application by viewing the KeyCode on the Licensing Wizard.

The KeyCode must be placed in your application once before any SciChartSurface is shown or instantiated, for example AppDelegate (see below).

Applying the Trial License in Your App

The KeyCode must be set in your app once, and once only before any SciChartSurface instance is shown. Do this by calling the static SciChartSurface.SetRuntimeLicenseKey() method in AppDelegate.

Code samples below:

• Swift
• Objective-C
• Xamarin.iOS

//
//  AppDelegate.swift
//  SciChartSwiftDemo
//
 
import UIKit
import SciChart

@UIApplicationMain

class SCSAppDelegate: UIResponder, UIApplicationDelegate {

 var window: UIWindow?

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        // Note! This is just an example. 
        // The real License KeyCode is found by following steps above
        SCIChartSurface.setRuntimeLicenseKey("YOUR_KEYCODE")
 
        return true
 }

}

//
//  AppDelegate.m
//  SciChartDemo
//
 
#import "AppDelegate.h"
#import "SCDConstants.h"
 
// NOTE: Import SciChart.h 
#import <SciChart/SciChart.h> 
 
@interface AppDelegate ()
 
@end
 
@implementation AppDelegate
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
     
    // Note! This is just an example. 
    // The real License KeyCode is found by following steps above
    [SCIChartSurface setRuntimeLicenseKey:@"YOUR_KEYCODE"];
     
    //...    
    return YES;
}
 
@end

using Foundation;
using UIKit;
using SciChart;

namespace XamarinTestingLicensing
{
    // The UIApplicationDelegate for the application. This class is responsible for launching the
    // User Interface of the application, as well as listening (and optionally responding) to application events from iOS.
    [Register("AppDelegate")]
    public class AppDelegate : UIApplicationDelegate
    {
        // class-level declarations

        public override UIWindow Window
        {
            get;
            set;
        }

        public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
        {
            // Override point for customization after application launch.
            // If not required for your application you can safely delete this method
 
            SciChart.iOS.Charting.SCIChartSurface.SetRuntimeLicenseKey("YOUR_KEYCODE");

            return true;
        }
    }
}

Activating a Paid SciChart iOS or macOS License

If you have purchased SciChart iOS v3 and later or macOS v4, you should have received a confirmation e-mail with a Developer Serial key and Runtime key. You can also view purchased license keys and serials in your Profile Page. If you don’t have one, please contact SciChart Sales.

 

To activate the license so that you can receive Technical Support, download the cross platform licensing wizard and install on your Mac desktop.

Download Windows Download Mac

Once installed, and you have logged in with scichart.com account, you can activate the developer serial you received when you purchased.

After activation you will see your license status on the wizard homepage. You can click ‘Runtime key’ to show the runtime license key that you must include in your app.

The KeyCode must be placed in your application once before any SciChartSurface is shown or instantiated, for example AppDelegate (see below).

Applying the Runtime License in Your App

The KeyCode must be set in your app once, and once only before any SciChartSurface instance is shown. Do this by calling the static SciChartSurface.SetRuntimeLicenseKey() method in AppDelegate.

• Rich interactions – allowing you to zoom and pan the chart, drag the axis to scale. You can add a data point selection, series selection and multiple selections with the cmd button.
• Annotations and markers – annotations API allows you to overlay Line, Text, Boxes, or watermarks over the chart, at specific data-point locations as well as displaying custom markers or points of interest.

• Cursors and tooltips – featuring rich Chart Modifier API for cursors & tooltips out of the box, including Cursors, Crosshairs, Tooltips, or Rollovers (showing vertical lines) as well as Legends. You can style a tooltip to fit your application for Mac look and feel.

• Styling and theming – SciChart’s macOS Chart Library ships with 8 stunning themes in a Theme Manager, which you can apply to your charts with a single line of code. Themes affect default cursor, zoom, axis, grid and series colors. You may customize even further and create your own custom theme, styling each part of the chart.

And there is more, SciChart for macOS allows linking multiple charts, per point coloring with the palette provider API. Have a look at all SciChart iOS and macOS features.
