Actualizaciones en v8.0.0

Características

Added

• Added point stroke style APIs to XY point series, Polar point series, buttons, legend entries and cursor point markers.
  • Allows drawing line stroke along edges of points.
  • For example, PointLineAreaSeries.setPointStrokeStyle.
• Added ChartWithCursor.setCursorDynamicBehavior.
• Added new ChartXY axis title position option: "center-chart".
  • Positions axis title to center of whole chart, rather than center of the axis only.
  • Useful for aligning axis title nicely relative to chart title or legend.
• Added HighlightModes.onHoverIndividual.
  • Relevant only for FigureSeries, allowing individual highlighting of figure that is under pointer.
• Added LUT.formatter.
  • New convenient way to specify formatting rules for LUT values, affecting both cursors and legends at once.
• Added Axis support for negative tick lengths and paddings, and new label alignment option, effectively adding support for inverted axis labels (displayed inside series area rather than outside).

Changed

• Reworked legends.
  • Focused on a better chart look, easier setup, more built-in options, and plugins for customization.
  • For more information and migration instructions, please read migration guide in developer documentation.
• Changed DataSetXY and PointLineAreaSeries APIs to allow more functionalities and optimizations.
  • Includes shared timestamps, separate data storage format configurations, and data mapping.
  • Please read migration guide for more detailed information.
• Changed ChartXY.addLineSeries, addPointSeries, addPointLineSeries, addStepSeries, addSplineSeries, addAreaSeries to return PointLineAreaSeries instead of previous deprecated series.
  • More details can be found in migration guide.
• Made significant CPU performance optimizations for scrolling or otherwise updating ChartXY applications.
• Point series now draw borders around points by default.
  • Previous behavior can be restored with PointLineAreaSeries.setPointStrokeStyle(emptyLine).
• Improved default cursor auto fitting to work better with small charts.
• Series entries in legends and cursor result tables now include borders.
• Reworked default cursor point marker styles.
• Changed default ChartXY axis title position from "center" to "center-chart".
  • This change is only applied for axes that don't have any stacks (several axes adjacent to each other).
• Improved Funnel and Pyramid chart label positioning.
• Default cursor formatters no longer display "X" or "Y" in case of axis without titles.
• Optimized loading speed and memory consumption of majority of 3D series by ~20%.
• Wrapped Axis.addBand parameter to an object parameter. See migration guide for more details.
• Wrapped Axis.addConstantLine parameter to an object parameter. See migration guide for more details.
• Slightly changed default positioning of X axis titles in ChartXY.
  • Changed from "center of axis" to "center of chart" to better align with new legends and chart titles.
  • Previous behavior can be restored with chart.axisX.setTitlePosition('center').
• Added few new required properties to Theme definition.
• Tweaked built-in cursor formatting in situations with only 1 series with some data pattern. Previously shown like "series, x, y" now shown with same pattern as when there are several series "x, series: y" to avoid discrepancies between the two common scenarios.

Removed

• Removed AxisScrollStrategies.regressive, fittingStart, and fittingEnd.
  • See migration guide for more details.
• Removed Cursor.setAutoFitStrategy, AutoFitStrategy, AutoFitStrategyFactory, and AutoFitStrategies.
  • These APIs were simplified to just a boolean flag "auto fit enabled" on cursors.

Correcciones

• Fixed issue where DataSetXYEventMap events are not firing if subscription is done via PointLineAreaSeries.
• Fixed issue where scrolling heatmap sometimes throws unhandled errors when using invalidateIntensityValues for time-series scrolling use cases after running for a while.
• Fixed issue where license error messages sometimes remain even after successful license verification afterwards.
• Fixed issue where LegendOptions are not working on TextSeries.
• Fixed issue where FigureSeries changing figure dimensions sometimes changes draw order between figures belonging to the same series.
