  • Experimental responsive features and default rules are now active. More info.
  • New Tooltip proprety: keepTargetHover – will make target element hovered as long as its tooltip is hovered, good for bullets and map images.
  • New Tooltip proprety: targetSprite – contains reference to element this tooltip is displayed for, if any.
  • New PictorialStackedSeries properties: startLocation and endLocation – allow setting relative start and end positions of the shape to fill.
  • New FunnelSeries/PyramidSeries/PictorialStackedSeries property: labelsOpposite – allows controlling which side of the series to show labels when alignLabels = true.

Changed

  • Accessibility: Default role of the Legend’s item containers was changed to “switch”.
  • Hiding or showing an element will now automatically set its readerHidden attribute accordingly.
  • On MapPolygon default value of nonScalingStroke is now set to true (as false).
  • When calculating font size for a word on a WordCloud chart it now uses smaller side of the series area instead of height.
  • Tooltip‘s label paddingBottom default value changed from 6 to 4 pixels for better centering of text.
  • Default value of minFontSize in WordCloudSeries to 2%.
  • Default value of maxFontSize in WordCloudSeries to 20%.
  • Label sizing algorithm updated in WordCloudSeries.

Fixed

  • Accessibility: Legend’s containers when toggling items were setting value of aria-checked incorrectly.
  • JSON: Using children with an array value was duplicating elements.
    Working around a bug with Angular’s dead code elimination in --prod mode.
  • Fixed ValueAxis issue with animation when there’s only single data item.
  • Sometimes axis ticks on a chart with a lot of data/series were not positioned properly.
  • Sometimes baseInterval = "year" on a DateAxis could cause stack overflow.
