Changed​

    • Improves GL memory usage. Same line now takes 40 to 70% less GL memory depending on the line.
  • PointSeries now uses faster rendering methods on supported devices.
    • Major performance improvement
    • Uses less GL memory
  • columnSpan and rowSpan Dashboard options are now optional and default to 1.
  • Chart options when creating a chart inside dashboard are simplified.
    • Options are no longer behind a separate object but are instead given in same object as the dashboard options.
  • Reduced zooming animation duration
  • Made transparent backgrounds possible.
  • LightningChart JS now requires the following WebGL extensions to work properly
    • ANGLE_instanced_arrays
    • EXT_blend_minmax
    • OES_element_index_uint
    • OES_standard_derivatives
    • OES_vertex_array_object
    • WEBGL_lose_context
    • If any of these extensions is missing, then a dismissible warning will be shown to notify users of possibly incorrectly working features.
  • Changed seriesBackground mouse and touch event naming to chartBackground mouse and touch events.
    • e.g. onSeriesBackgroundMouseDown was changed to onChartBackgroundMouseDown
  • requestAnimationFrame and cancelAnimationFrame are no longer polyfilled automatically.
    • The methods should be polyfilled if support for environments where the methods don't exist is needed.
  • Numeric Axis ticks have been reworked
  • DateTime Axis ticks have been reworked
  • Mouse and touch events are properly handled to allow normal browser interactions when chart does no action for the event
  • Changed ColorHEX factory color syntax to follow CSS color syntax, #RRGGBB[AA]
