[5.20.0] - 2026-07-22

Added

  • New StarPattern and TrianglePattern fill patterns added. More info
  • RectanglePattern now supports a rotateShapes setting. When true, rotation rotates each rectangle around its own center instead of the whole grid which makes it faster.
  • New themes: Midnight, Ember, Nord, NordDark, Pastel, PastelDark, Colorblind, ColorblindDark (Okabe-Ito, color-blindness safe), Patterns, PatternsDark, Petroleum, Savanna.
  • New dark variants of the existing themes: DatavizDark, KellyDark, MaterialDark, MoonriseDark, SpiritedDark, FrozenDark.
  • Two new parameterized themes : Monochrome (a single-hue lightness ramp with an optional accent) and Adaptive (generates a full palette from one or two base colors). More info
  • XYChart has new strokeWidths and strokeDasharrays settings — arrays cycled across line series as they are added, the same way colors cycles series colors.
  • XYCursor has a new clickTolerance setting: how far outside the plot area (in pixels) a press can start and still begin a zoom/selection (the selection still starts on the plot edge). Default: 0 (current behavior).
  • New globalpointerdown event on all elements, fired on a press anywhere on the chart surface (mirrors globalpointermove/globalpointerup).

Changed

  • The Volume Profile indicator now distributes each bar's volume across the full high/low price range it traded, instead of placing the whole bar at its closing price.
  • Label's oversizedBehavior: "truncate" now ignores maxHeight setting (because there's no way to truncate text vertically).
  • Stock chart indicators now enforce sensible min/max limits on their numeric settings, so extreme values can no longer freeze the page (e.g. a Volume Profile row count of 24000) or break an indicator. IIndicatorEditableSetting gains maxValue and step.
  • New properties on Indicator editable settings: scale, maxValue, step. More info
  • Acceleration Bands' factor now displays as the conventional 1 instead of 0.001.
  • If a bullet's Graphics has no paint settings set (fill, fillGradient, fillPattern, stroke, strokeGradient) it will inherit all those from parent series.
  • New Series settings: fillGradient/strokeGradient.
  • PathPattern now repeats the svgPath on as a grid instead of drawing once and letting rendering engine repeat it.
  • An XYSeries value field (e.g. valueYField, openValueYField) can now be changed dynamically after the series is created; re-set the series' data afterwards for the change to take effect.
  • A Container's Rectangle/RoundedRectangle background now defaults crisp to true (for sharper edges/strokes) unless crisp is set explicitly.
  • An XYSeries can now be reassigned to a different xAxis/yAxis after creation.
  • Accessibility: Focusable elements are not being sized on initial load until they are actually focused.
  • Accessibility: The <div> that holds chart's focusable elements will now have its aria-label set if ariaLabel is provided in Root settings.

Fixed

  • Logarithmic ValueAxis could show floating-point noise in its grid labels (e.g. 4,999.999999999999 instead of 5,000). Grid values are now rounded.
  • Logarithmic ValueAxis was showing 0 for grid values smaller than 0.00001 when no numberFormat was set
  • ValueAxis with syncWithAxis and autoZoom: false regressed in 5.19.0: wrong scale and a possible browser hang.
  • Acceleration Bands: the upper and lower bands were swapped to display appropriate upperColor/lowerColor.
  • Williams %R: used a period + 1 lookback and treated a missing high/low as 0; it now uses exactly period bars.
  • Momentum: skipped its first computable value; it now plots from period bars onward.
  • Relative Strength Index: returned 0 (maximum "oversold") for a perfectly flat market (0/0); it now returns a neutral 50.
  • Moving Average Cross: default fast/slow periods were inverted; the defaults are now fastPeriod: 9 / period: 21.
  • Volume Profile: no longer errors in ticks count mode when the visible price range is flat.
  • LinePattern with a non-zero angle could show a seam instead of tiling seamlessly.
  • LinePattern with a non-zero rotation could render broken/dashed lines after the tile-size optimization; the auto-shrink is now skipped when rotation is set.
  • RectanglePattern/CirclePattern with a non-zero rotation could render nothing on larger pattern tiles.
  • ChartSerializer now accounts for settings on start/end labels of a HeatLegend.
  • Width of the Label's underline could fluctuate in some cases.
  • A non-finite startAngle/endAngle on a RadarChart (e.g. NaN or Infinity) could freeze the browser.
  • Venn was not resetting its colors/patterns sets when data was cleared/re-set.
  • Classes that would not react/redraw to dynamic changes to some of their settings: CategoryAxis, DateAxis, ValueAxis, CategoryDateAxis, DurationAxis, XYSeries, ColumnSeries, StepLineSeries, RadarLineSeries, SmoothedRadarLineSeries, Treemap, VoronoiTreemap, Sunburst, Pack, ForceDirected, FunnelSlice, FunnelSeries, PyramidSeries, SerpentineChart, SpiralChart, Graphics, Rectangle, RoundedRectangle, HeatLegend, WordCloud, Flow, FlowLink, Chord, ChordDirected, ChordNonRibbon, ArcDiagram.
