v8.1 中的更新

特性

• Added new method overrides to HeatmapGridSeries.invalidateIntensityValues.
  • Allows inputting data in flat number format instead of number matrix, i.e. number[], Float32Array, etc.
• Added HeatmapGridSeriesIntensityValues.setAggregation (and same for scrolling variant).
  • Allows enabling automatic min/max aggregation.
• Added HeatmapGridSeries.setContours, SurfaceGridSeries3D.setContours and contoursFromLUT.
• Added HeatmapGridSeriesOptions.maxTileSize.
• Added new optional scale parameter to captureFrame and saveToFile methods.
• Added cursor parameters to ChartXYUserInteractions.
  • Allows configuring or disabling applied cursor property when interacting with an XY chart.
• Added MouseStyles.Grab, Grabbing.
• Added LineSeriesOptions3D.individualLookupValuesEnabled.
  • Allows inputting per data point lookup values for dynamic coloring.
• Added labelAlignment options to BarChart category and value labels.
• Added CustomTick.setTickLabelAlignment.
• Added chart property to most series classes for convenience.
• Added axisX, axisY, axisZ properties to 3D series for convenience.
• Added RectangleSeriesOptions.solvePlane.
• Added getData for PolarPolarLineSeries, PolarPointSeries, PolarPointLineSeries, and PolarAreaSeries.
• Added clear for BoxSeries3D.
• Added getCustomTicks for Axis, Axis3D, and ParallelCoordinateAxis.
• Changed RectangleSeries default cursor and solve nearest behavior.
  • If rectangle dimensions are progressive along X or Y plane, then cursor behavior is adjusted to work similarly as in other XY series (considering only progressive plane).
  • Previous behavior can be reverted by setting solvePlane: 'xy' when creating the series.

修补程序

• Fixed PointLineAreaSeries line rendering when using DashedLine and data has NaN values.
• Fixed capture APIs (captureFrame, saveToFile) not capturing latest changes sometimes if chart is not actually visible on the page.
• Fixed CursorXY.setKeepWithinAxisBoundaries not working.
• Prevented crash when combining DashedLine stroke with logarithmic scale.
• Combination is still not supported but application crash is prevented.
• Fixed Band.removeEventListener type issue not accepting all event types that are supported by addEventListener.
• Fixed FigureSeries.setPointerEvents doesn't work after first rendered frame.
• Fixed ChartXY user interaction rmb pan (default) end also triggering other interactions that should be fired on rmb click.
• Fixed PolarPointSeries not working with IndividualPointFill style.
• Fixed BarChart logarithmic value axis not working if orientation is horizontal.
• Fixed user interactions API issue where wheel triggered interaction is not triggered if lmb is not explicitly set to true.
• Fixed BarChart issue where repeatedly setting data could result in legend showing duplicate entries.
