LightningChart® Ultimate v.7.2.6 released

LightningChart® maintenance v.7.2.6 with some improvements and bug fixes is now released! Available at the Download Center.

Changes, v.7.2.5 -> v.7.2.6


  • Small performance improvements on Smith & Polar view EMF exports when zoomed in.
  • ChartError event is produced when LightningChart is forced to recompile some shader. This allows users to detect and solve situations where chart takes a long time to initialize due to shader compilation.


  • Thick 3D Contour lines look better.
  • 3D Contour lines are clipped on DX9 rendering.
  • WPF Chart does no longer throw exception when its visibility is set to Collapsed.
  • Axis nib dragging to screen border works with HighDPI mode as well.
  • HighLowSeries IsMouseOver method handles points correctly.
  • Zoomrect is properly clipped when required when RectangleZoomAboutOrigin is set to true and manual aspect ratio is used.


  • Smith and Polar series (SeriesBaseRound) OwnerView property returns ViewRoundBase, instead of ViewPolarBase.
  • Property is now usable with Smith series, but the return type has changed and might require attention from ViewPolar users.
