Added

• Added new chart type, MapChart.
  • MapChart has multiple views for visualizing data in different regions of world.
  • Supports real-time data updates with high FPS.
• Added new series type, PolygonSeries.
  • This series can be created with ChartXY.addPolygonSeries.
  • PolygonSeries.add returns you a PolygonFigure object which can be used to style the polygon.
• Added improved series type HeatmapGridSeries.
  • This series can be created with ChartXY.addHeatmapGridSeries.
  • Replaces the existing IntensityGridSeries (ChartXY.addHeatmapSeries) which is now considered deprecated and will be removed in next major release.
  • This new series type provides considerably better performance compared to the previous version.
• Added new series type HeatmapScrollingGridSeries.
  • This series can be created with ChartXY.addHeatmapScrollingGridSeries.
  • Provides a way to create scrolling heatmap with data cleaning support.
• Added new methods to help to make better experience on devices with smaller screens.
  • UIElement.setAutoDispose, UIElement.getAutoDispose
• Added High precision XY Axis.
  • New XY Axis type that allows zooming to smaller axis intervals with drawback of decreased performance. Refer to AxisOptions documentation for instructions.
  • This is considered an experimental feature and might be changed in a minor or major release with no backwards compatibility.
• Added AxisTickStrategies.Time.
  • New automatic ticks strategy for depicting axis intervals between hundreds of hours and individual nanoseconds.
• Added TimeFormattingFunctions helper methods for formatting millisecond time stamps to different time string formats.
• Added LUT parameter to UILUTCheckBox.setLUTStepValueFormatter callback.
• Added new options to LUT, LUT.valueRangeMin and LUT.valueRangeMax.
• Added new control for suppressing warnings that are mostly useful when developing, LightningChartOptions.warnings.
• Added NumericTickStrategy.formattingOffset, works similarly to DateTimeTickStrategy.setDateOrigin.
• Ability to rotate all texts.

• Added UIElementBuilders.LUTRange.
• Added more control to how 3D series are shaded.
  • Series3D.setColorShadingStyle, Series3D.getColorShadingStyle
• Added new Shading style ColorShadingStyles.Simple.
  • This shading style can make some 3D visualizations look better by removing all shading and using the object colors directly.
  • Using this shading style can improve performance on low end devices.
• Added new Shading style ColorShadingStyles.Phong.
  • This has been the default shading style for all 3D features since the 3D features were introduced.
  • You can now control ambientColor, ambientReflection, diffuseReflection, specularReflection, specularColor and shininess options.
• Added ChartXY.addOnScreenMenu.

Changed

• FormattingFunctions.Numeric now also works for more than 3 decimal parts.

• PointSeries3D performance has been greatly improved overall.
• LineSeries3D performance has been greatly improved overall.
• PointLineSeries3D performance has been greatly improved overall.
• Removed empty UI backgrounds from all default UI builders. This makes it easier to style UI backgrounds - afterwards, only using setBackground(bg => bg.setFillStyle(...)) will always be enough.
• Changed UI default background behavior - now ALL UI elements will always have background styled according to Theme by default. To hide background, use setBackground(bg => bg.setFillStyle(...)), etc.
• DateTimeTickStrategy default cursor formatting now falls back to major ticks formatting if minor ticks are disabled.
• Improved LUT precision.

Fixed

• Improved 3D color shading, and fixed some cases with incorrect lighting.

• WebGL context wasn't marked as 'lost' when chart/dashboard was completely disposed.
• Fixed GL_INVALID_VALUE : glScissor warning.

• Fixed 3D Point Line Series point size not updated to match highlight size when highlighted.
• Fixed 3D Point Line Series point size could be smaller than line thickness, after changing line thickness, resulting in visible gaps in line.
