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!

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.

SciChart’s Visual Test Framework allows UIAutomation and image comparison for the Export to XPS/Png 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.

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.

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!

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.

The post SciChart WPF: New set of tutorials now online appeared first on WPF Charts, iOS and Android Charts | SciChart.

We spent a little bit of time at the weekend open-sourcing one of the libraries that we use in the SciChart WPF Examples Suite and Licensing Wizard which handles cool animation effects!

You’ve seen the cool animation effects in the WPF Chart Examples Suite right? Well we’ve achieved this using the now open-sourced Transitionz WPF library!

This cool little library allows you to animate Opacity, Translate Transform, or Blur.

Transitionz.Blur, Translate and Opacity on Visibility Changed

You can do really complex things and trigger animations on loaded, on Visibility Changed or on Property Changed via bindings. We use it in the SciChart WPF Examples Suite as well as the Licensing Wizard to achieve these cool effects.

Transitionz.Blur, Opacity and Translate used in the Licensing Wizard app

If you want to include Transitionz in your app and have cool animation effects, you can get it for free from NuGet as the SciChart.Wpf.UI.Transitionz package (licensed under Apache 2.0 – free for commercial use). Alternatively, we have also published the full source to Github.

For usage instructions please see the Transitionz-Library wiki page.

Enjoy!

On the Microsoft site, they have announced earlier this year in fact that support has ended for the .NET Framework 4.0, 4.5 and 4.5.1 whilst continuing to develop .NET Framework 4.5.2 and 4.6.

Microsoft says their decision to end support for older versions of the .NET Framework will allow them to invest more resources towards improvements of the .NET Framework.

SciChart v4 currently supports .NET Framework v4.0, 4.5 and 4.6. We plan to keep supporting as wide a range of .NET Frameworks as long as possible.

Ideally however, we need to drop support for .NET 4.0. This is because some dependencies we use (such as SharpDX, used by SciChart.DirectX package) now only support .NET 4.5 and up. However, we would like to know from you if this will affect you negatively in order to decide when to do this.

Please take a moment to answer our survey below if you are using .NET 4.0 only for deployment, or plan to use .NET 4.5.2, .NET 4.6 for current or future projects.

Survey: .NET Framework Support Versions

Question: Are you currently supporting .NET 4.0 in your current & future applications? Are you planning to upgrade to .NET 4.5.2 or .NET 4.6?

Please take a moment to answer our survey below.

The post Survey: .NET Framework 4.0, 4.5, 4.6 Support Versions appeared first on WPF Charts, iOS and Android Charts | SciChart.

We are pleased to announce a Minor Update to the SciChart WPF SDK v4.1.

This release adds new features requested plus fixes some critical bugs which have been reported by our users over the past few weeks.

If you are using SciChart v4.x then this update is backwards compatible and is a drop-in replacement. If you are still using SciChart v3.6.1 we invite you to take a look at SciChart v4 and our migration guide. We’ve made it easier than ever to jump to the latest major version!  

What’s New in v4.1.1.8645?

New Features (3D Charts)

• Added new feature : rasterizer states. This now allows rendering with culled back faces.
• Added support for immediate drawing of meshes with light. It is possible to work with lighting, although the new BeginLit needs to be used, and a normal should be set before drawing any face.

Fixed (2D Charts)

• SC-3551 Fixes critical bug introduced in v4.1.0 where FIFO Series did not display properly, and non FIFO series resampled as MinMax always drew a line back to 0,0 at the end.
• Fixed issue in LineAnnotation when it get NaN coordinates.
• Fixes crash where Tab out or Lost Focus of SciChartScrollBar = exception.
• Fixed serialization(exporting) of charts with Styles.
• Fixed serialization\deserealization(exporting) of GridLinesPanelStyle.
• Fixes serialization\deserealization(exporting) of VerticalSliceModifier (without tooltips for now).
• Fixed alignment of wicks in Candlesticks.
• Added IncludeSeriesProperty attached property to DataPointSelectionModifier. Default TRUE.
• Reverted caching of DataSeries GetIndicesRange(). In some cases this causes instability.
• Updated the Ternary Chart documentation.

Fixed (3D Charts)

• Moved CustomPointMarker3D outside of SciChart.Charting3D.
• The Point Cloud 3D example: added code to demonstrate how a custom texture can be used as a point marker.
• The Point Cloud 3D example: now has a new option that shows a custom texture in usage. It creates a cross shaped texture.
• Renamed the SciChartTexture enum for the template textures and meshes with word SciChartTextureTemplate to avoid confusion.
• DefaultPointMarkers.cs now has a en example of how a custom texture can be used with point markers, what needs to be done is creating a Texture2D in the constructor, and retrning it in the getter, and adding a Dispose function.
• Fixed bug where WorldDimensions change does not result in SC3D Mesh or Scatter or PointLine mesh change.
• Fixed recreation of mesh EVERY frame (last WorldDimensions was not stored).
• Fixed a bug in SurfaceMeshSceneEntity where surface mesh does not change size if SciChart3DSurface.WorldDimensions changes size.
• Fixed PointsMesh, it was not setting a texture, there fore the example was always using rectangles and no triangles or circles.
