LightningChart .NET v.12.1.1 is out now!
New features, bug fixes, improved interactions, and better performance.
HexagonShape available for Points and Markers
We are introducing the hexagon shape available for the Points (series.PointStyle.Shape) and Markers (Symbol.Shape) properties.
Like other geometrical shapes, the Hexagon shape allows body coloring with a two-color gradient, as well as with a separate color for the border. The hexagon shape also supports export to raster/bitmap or vector images.
Improving 3D Interactions
In this release, we have greatly improved 3D interactions like zooming, rotation, and panning for objects that render as large surfaces, e.g., SurfaceGridSeries3D, SurfaceMeshSeries3D, and MeshModel.
The performance in a mid-level computer will increase at least twice and when using a high-end graphics card, the speed can be up to 10x faster. Similarly, 2D interactions like zooming and panning will be much faster for the FreeformPointLineSeries when the point count is in millions.
Other Improvements
Large ValueRangePalette Improvement
ValueRangePalette is a property that can be used by line series, intensity series, polar line series, surface 3D, etc. Previously, if the palette had to load more than 20 steps, the chart became very delayed. Now, the user can feature hundreds of steps in the palette without any performance penalties. However, to create a smooth palette (color bar), you don’t need to use hundreds of steps instead, you can use the PaletteType.Gradient with only a few colors that will interpolate in between.
Improved VolumeModel binding
While the LightningChart MVVM edition works with VolumeModel, the binding to this class did not work properly. Now, VolumeModel binding errors are fixed and overall performance is improved.
Improved in zooming behavior for XY block-line-series
While XY block-series (SampleDataBlockSeries, LiteLineSeries, DigitalLineSeries) greatly improved application performance and reduced memory usage, in certain circumstances they caused AccessViolationException in the past. In particular, when the chart has a lot of points (e.g. 200M for LiteLineSeries) and deep zoom-in is performed. Now the issue is fixed and zooming will not cause AccessViolationException.
