In earlier stages, LightningChart provided different tools that required users to write additional code in order to enable the data tracking functionality. Later, the XY DataCursor built-in functionality was introduced during the recent LightningChart v.10.4 release.

Now, we’re glad to announce that the DataCursor built-in functionality is enabled for all 3D, Polar, and Smith series as well. As a refresher, the DataCursor functionality allows the user to explore a series and the closest value to the mouse cursor will be automatically tracked. This will display the result data within a table on the chart, as shown below:

Additionally, here you can see a table of the public properties for the DataCursor feature:

The TransparencyRenderMode property is now available for 3D surface series including:

•  SurfaceGridSeries3D
• SurfaceMeshSeries3D
• WaterfallSeries3D

and for the PointLineSeries 3D. LightningChart offers 3 options for handling transparency of the surface: Unordered, ShaderApproximation, and OrderingTriangles. The new feature helps to mitigate artifacts and improve translucent object handling in the chart.

Notice that this new way how to handle a translucent surface or line is only available when using DirectX 11 rendered, i.e., when the RendererDeviceType is set to HardwareOnlyD11 or SoftwareOnlyD11.

In this release, the target version for LightningChart’s library is updated to .NET Framework 4.6.2. Any user’s project, which uses LightningChart’s library, should set a target framework of at least .NET Framework 4.6.2. Any newer version, like .NET Framework 4.8 or .NET 7.0, is fine as well.
