[6.0.0] - 2024-08-06

Original release news here

Added

• Added new, refactored Cursor API
  • Added new functionalities, such as multi-series cursors, 3D cursors and more.
  • Please refer to migration guide and docs > Features > Cursors for more information.
• Added new, fully reworked GaugeChart
  • Improved default look, improved adaptibility to different user interfaces, added built-in value indicators functionality, added built-in Needle functionality, added value based background glows and gauge bar coloring.
  • API is completely changed. Please refer to migration guide if you are migrating from old gauge chart API (https://lightningchart.com/js-charts/docs/migration-guides/)
• Added new, simplified SolveNearest API
  • Refer to migration guide and developer documentation for more details.
• Added SeriesXY.setClipping
  • Allows reverting back to previous behavior, where series rendering could leak outside its owning axes in stacked axis applications. Defaults to enabled (true)
• Added PointShape.HollowCircle
• Added Chart3D.setProjection (beta)
• Added event API for tracking user interactions on Axis titles
  • Axis.onTitleMouseEnter, ...
• Added Axis.setTitlePosition
  • Allows changing axis title position between pre-determined key locations.
• Added x and y options to DataSetXY.alterSamples
  • Slightly more convenient way to alter 1 sample at specific index with specific X and Y values.
• DataSetXY and PointLineAreaSeries can now directly consume x and y coordinates from Date objects or valid date-time strings.
  • Rather than user having to map them to Date object and use getTime() method.
• Added FormattingFunctions.Scientific
  • Formats numbers like '0.00e+3'
• Added EmptyTickStrategy.setCursorFormatter
  • Useful in use cases of manual tick placement. Instead of specifying formatting with CustomTick.setTextFormatter, you can specify a cursor formatter, which is automatically utilized by cursor result tables as well.
• Added CursorXY.setTickMarkersAllocateAxisSpace
• Added CustomTick3D.setBackgroundFillStyle, setBackgroundStrokeStyle, setPadding
• Added Chart3D.translateCoordinate capability to translate 3D axis coordinate to client and relative coordinate systems.

Changed

• XY series connected to stacked axes are now clipped so rendering doesn't leak outside the owning axes.
  • Previous behavior can be restored per series using SeriesXY.setClipping method
• Enhanced the layout of Pie, Funnel, and Pyramid charts.
  • Labels are now hidden for Pie charts with a radius smaller than 50px.
  • For Funnel and Pyramid chart labels are hidden when the chart width or height is smaller than 250px
• Tweaked default area series fill styles to utilize more transparency for a more modern look.
• Improved DateTime Axis tick strategy zoom range
  • Previous min interval ~1 second. Now ~1 millisecond.
  • Also improved default formatting at minute/second zoom levels.
• Tweaked darkGold and light themes cursor gridlines to have more contrast.
• LCJS drag events are now stopped whenever any draggable HTML event is dragged on the web page.
  • Change made because of use case where user could not interact with HTML event even when it had pointer event priority.
• Disabled DateTime great ticks ticklines by default
  • Frequently requested by users
• Inverted sorting order of the TreeMap chart

Fixed

• Fixed charts sometimes not adjusting to browser zoom level change before something changes in chart.
• Fixed series sometimes leaking 1 or 2 pixels outside series background in ChartXY
• Fixed crash with PointLineAreaSeries automatic max sample count control.
• Fixed RectangleSeries render errors with high precision axis. Errors happened very inconsistently with very specific rectangle coordinates.
• Fixed text rendering issue sometimes present for 1st frame in apps with relative large number of text objects, where text is rendered as strange symbols
• Fixed MapChart coloring regions with no data with first LUT color, instead of using fallback color.
• Fixed crash with ZoomBandChart inside Dashboard "Cannot compare node with itself"
• Fixed PointLineAreaSeries Y axis scrolling 1 frame behind.
• Fixed XY heatmap and scrolling heatmap series not accepting axisX or axisY options
• Fixed ZoomBandChart misalignment when connected to multiple stacked axes
• Fixed custom tick label padding sometimes wrong.
• Fixed PointLineAreaSeries hiding points when zoomed out even if both stroke + area are disabled.
  • Essentially it was not possible to use progressive scatter visualization
• Fixed ZoomBandChart not mimicking PointLineAreaSeries point style fully (rotation, shape, size)
• Fixed PointLineAreaSeries crash when supplied only data points with exact same x
• Fixed DataSetXY append methods not working correctly with start and step options
