Original release news here

Added​

  • Added scaleThemeFontSize
    • Convenience function to up or downscale font sizes as well as tick lengths, element paddings, etc. to make font sizes sit in nicely.
  • Added Axis.getSeriesDataRange
    • Quality of life method to get data extents of all series attached to an Axis
  • Added new capabilities to AxisScrollStrategies.
    • For fitting, expansion and fittingStepped you can now specify whether it should affect axis start and/or end. By default affects both sides.
    • Added scrolling. This is the replacement to now deprecated progressive and regressive. It also has a new feature for real-time scrolling in use cases where data arrives infrequently (every 1s etc.)
  • Introduced HTML text rendering option (beta)
    • Can be enabled for sharper text display where required with drawback of weaker performance.
    • For more information refer to HTML text rendering section in developer documentation.
  • Added singleClick option to setUserInteractions restoreDefault and restorePrevious interactions.
    • Allows firing the interactions on single click (lmb/rmb/mmb)
  • Added Axis.setScrollMargins method for controlling automatic spacing between axis edges and series.
  • Added ZoomBandChart.setStopAxisOnInteraction
  • Added some missing APIs to ZoomBandChart
    • getLayout
    • chart
    • Some events to addEventListener
  • Added optional skipIntervalRestrictions parameter to Axis.setDefaultInterval
    • Situationally useful as previously setting axis default interval always ignored any interval restrictions

Changed​

  • Improved zoom capabilities of AxisTickStrategies.DateTime
    • Now allows zooming up to individual nanoseconds.
    • Nanosecond timestamps must be loaded to charts as Float64 after shifting to start from 0 and converting to milliseconds.
  • Improved radial gradient quality
  • Domain locked license keys now allow running charts inside same origin iframes
  • LightningChart JS now adds overflow: hidden to its container DIV style always.
  • ChartXY default cursor formatter now displays axis titles (if any) instead of "X" or "Y".

Fixed​

  • Fixed cursor performance degradation (CPU use is increased after cursor is shown with a lot of content, even if cursor is hidden afterwards)
  • Fixed Axis.setTitleRotation sometimes not updating title display.
  • Fixed PointLineAreaSeries render error when zoomed out and coordinates are larger than 10^16
  • Fixed ZoomBandChart not automatically adjusting if connected to an inverted axis.
  • Fixed PyramidChart, PieChart, FunnelChart not being able to display negative values.
  • Fixed some small effect rendering errors
    • Glows becoming "dashed" in Chart3D bounding box borders sometimes.
    • Glows cutting off slightly before ChartXY series area edges.
    • ChartXY series background border drawn above glow effects.
