SciChart WPF v4.2.2 Build 9777 Released!
Posted by Julia Skorobogata on 17 February 2017 03:25 PM

We are pleased to announce the release of SciChart v4.2.2 Build 9777. This is a minor update which contains many critical bug fixes and minor improvements. It is strongly advised for users of SciChart v4.x to upgrade to this version, which is a drop-in replacement.

We’re committed to providing our customers with the best experience possible, and as a result, we continue to update and improve our popular WPF Charts components!

 

What’s New in v4.2.2?

Critical Bug Fixes
  • Updated Installer to force upgrade / uninstall of old version of scichart when installing 4.2.2. Fixes issue where SciChart Licensing Wizard crashes after install when a previous version was installed
  • Added some lock(SyncRoot) to public methods on DataSeries where getting indices range, or getting Y Range. Prevents race conditions and crashes.
  • SC-3946 VerticalLineAnnotation. ShowLabel crashing issue. Fix for Null reference exception in MouseDown event in a AnnotationLabel. fix for “disappearing proper Labels in VerticalLineAnnotation”
  • SC-3918 Fixed 3D VertexSelectionModifier crashes in some cases
  • Fix for memory leak in series binding (Ticket “Releasing Heatmap2DArrayDataSeries from memory”)
  • Test for releasing memmory when Collection is changing in Series biding.
  • Test for memory leak in Series binding caused by unsubscribing from ParentSurface event.
  • SC-3862 On Finalize of SciChartSurface in an ItemTemplate, you get occassional ‘Element has already has a logical parent. It must be detached from the old parent before it is attached to a new one’ error. Stopped removing Axis from SciChartSurface in Unloaded handler in Finalizer . SuspendUpdates around UpdateLayout() in PrepareSurfaceForExport stops exceptions thrown/caught in export
  • SC-3857 Fixed the issue when LogAxis threw if VisibleRange contained NaNs (https://abtsoftware.myjetbrains.com/youtrack/issue/SC-3857)
Other Bug Fixes

  • SC-3926 Rollover/Cursor/Tooltip wrong tooltip for the last point in a digital series
  • SC-3199 Fixed “Create Custom Theme” example – no render series appear. because of Freeze AttachedProperty we can not create a modifieble copy of brush for XAML renderer

SciChart Xamarin.iOS, Xamarin.Android Bindings ALPHA
Posted by Andrew on 16 December 2016 06:03 PM
scichart-xamarin-demo-landscape

Xamarin.Android and Xamarin.iOS enables development of SciChart mobile apps in Visual Studio!

We’ve published what is a very very early Alpha version of the SciChart iOS & Android Xamarin Bindings to our NuGet feed and Github today. These are binding libraries (thin wrappers) around our existing SciChart iOS & Android Native Chart Components.

You can clone the repository for the SciChart Xamarin Examples here. This builds in Visual Studio 2015 with Xamarin 10.3. Also, you can get the NuGet packages for SciChart.iOS, SciChart.Android from our SciChart official NuGet Feed.

SciChart Xamarin Examples are open source on Github

Currently the Android examples are completed and working, iOS Examples are a work in progress. The SciChart.iOS and SciChart.Android Xamarin DLLs are v2.0 Alpha. Full release will be expected in January as we aim to release SciChart iOS & Android v2.0 at the same time.

To build the examples, you will need Visual Studio 2015 and Xamarin 10.3.

  • For Android, you will need to setup the development environments for Android SDK and NDK as per our documentation, with Java SDK 8.
  • For iOS, you will need a real Mac OSX machine to act as a build agent. XCode 8.2 and Xamarin Studio with Xamarin.iOS is required on the Mac to build and deploy SciChart.iOS.

Full dev setup instructions coming soon!

Next week we expect to add a host of iOS Chart examples, and please be advised the API is still in flux as we unify iOS & Android and ensure the two platforms have similar APIs.

More coming soon!

Best regards,
[SciChart Team]

SciChart WPF v4.2 Build 9172 Released!
Posted by Andrew on 23 November 2016 09:00 AM

So those of you who have been watching our releases page will notice that SciChart iOS & Android v1.2 were released several weeks ago, but SciChart WPF is no-where to be seen!

Well, the good news is that while we have been delayed in our SciChart WPF v4.2 release, we are now ready to publish it! The delay was due to an extra round of testing & bug fixing (over and above the norm for SciChart releases) in order to make this one of the most stable and perfected releases of SciChart ever.

If you have a moment you can take a look at our Task Tracker board showing the status of the SciChart v4.2 Sprint. Our Issue Tracker was made public (read-only) a few weeks ago and you can now browse the status of sprints, tasks and bugs that you have reported.

Have a look below to see what’s coming soon.

XPS, Png Issues Fixed

In SciChart v4.2 we have literally fixed over 20 bugs related to Xps and Png export. The level of bugs in this feature was quite frankly, embarrassing, and we apologize to our users for putting them through this! In our defense, the image/XPS export feature is hugely complex, and requires us to make a perfect clone of the SciChartSurface in memory, and off-screen, for rendering to Png or XPS (Vector format) at a size other than the current chart.

Literally over 20 bugs reported and fixed related to XPS, Png export!

Literally over 20 bugs reported and fixed related to XPS, Png export!

This is now done and the export works beautifully. We have also explored various ways of UIAutomation testing and come up with a Visual Test Framework that compares expected vs. actual Bitmap / XPS outputs in a variety of edge cases, plus, created over 150 test cases to cover this extremely popular feature.

Improvements to SciChart3D

Some feature requests for SciChart3D have been added to SciChart WPF v4.2. These include the ability to switch from Right to Left Handed Coordinate systems, fixing issues with 3D Pointmarker Transparency and creating an example to demonstrate adding custom Cube Geometry and Text to the scene.

text-cube-geom-example

We have also added handling of order-independent transparency for some entities in the scene as well as the ability to create custom PointMarkers for 3D Charts.

Pie Chart and Donut Chart!

Hotly requested on our Features Survey a few months ago, as well as on the website more than once we have now fiiiinaaally added Pie Chart and Donut Chart to the SciChart WPF Charting SDK.

scichart-donut-chart-pie-chart-play

We don’t know why this chart type is so popular, but you wanted it, so we built it! We hope you like it!

Negative Logarithmic Axis

It is possible to show data points with negative values on a logarithmic scale. Use our new NegativeLogarithmicAxis for that!

Negative Logarithmic Axis

Some Minor Improvements

We’ve added a SciChartSurface.ZoomState property to allow you to know if the user is zooming or not. This is used in our Tutorials to allow real-time zooming and panning alongside realtime scrolling charts.

Oh and we’ve created 9 new tutorials to help new users get started with SciChart WPF.

We’ve added a DataSeries.Tag property.

We’ve added an overload to ExportToBitmapSource(Size) so you can specify a size before exporting.

We’ve also added SeriesValueModifier.IncludeSeries and SeriesSelectionModifier.IncludeSeries properties so you can hide a series from these modifiers.

We’ve made the DataPointSelectionModifier work with more series types such as Stacked series, Band Series and Bubble Charts.

We’ve added methods to ViewportManager to allow you to ZoomExtents in a delayed fashion after updating data via Databindings.

We’ve made the RolloverModifier MouseOver Hover mode work properly with Realtime-charts.

We’ve added support of PaletteProvider to FastBoxPlotSeries.

We’ve added the properties Viewport3D.ForceStallUntilGPUIdle and Direct3D10RenderSurface.EnableForceWaitForGPU which can be used to stall DirectX rendering until GPU is idle (resolves flicker on some older hardware).

Finally, SciChartLegend.Background is bound to LegendModifier.Background by default now.

A Bazillion Bug Fixes

There are also many many bug fixes in this release, and also a lot of UIAutomation tests and unit tests have been added to reduce the chance of them creeping back in in the future. The list of bug fixes in SciChart v4.2 can be found below.
