These are the recent changes for SciChart.JS since 2.1. Release notes for older versions can be found at SciChart.js News and Releases
This release contains a fix for a regression issue where autorange would fail when using category axis with large amounts of data, and other small fixes.
SCJS-1865 Fix auto Y range for resampled values when using Category XAxis
fix graphical artifact on rounded columns
drawLabels and isVisible now supported on 3D axis
SCJS-1830 updated typescript definition for IOverviewOptions.transformRenderableSeries to show it can return undefined
fix initial auto y range failing when animating a spline series
SCJS-1856 Overview now respects axis visibleRangeLimit
3D improvements and some small fixes
Separate labelStyle and axisTitleStyle for 3D axis.
is[XYZ]PlaneVisible property added to Scichart3DSurface
SCJS-1855 Tooltip values could be wrong for CategoryAxis with less than 10 data points
SCJS-1839 3D tooltips did not work on appended data
SCJS-1854 isHit was not set correctly for negative columns
Position on subcharts should be optional
Fixed Typedoc on yRangeMode. Drawn is the Default
SciChart.JS v3.5 - 3D Columns and autorange performance improvement
We are bumping the version number as we have added support for 3D columns. View the demo at https://demo.scichart.com/react/3d-column-chart
We have also done a significant optimisation to the way that y range is calculated for large datasets. When using y axis autoRange or zoomExtents we see performance improvements of 30 to 50% when plotting millions of points in a sorted line series.
ColumnRenderableSeries3D which uses XYZ data and supports per column coloring using metadata
Significant performance improvement for y axis autoRange
Spline series and series using RenderDataTransforms now support FifoCapactiy on the dataseries
Changed SciChartDefaults.enableResampling to debugDisableResampling
This releases fixes an recently introduced error that could occur when using nativeText labels, along with a fix for a potential performance issue in Chrome.
SCJS-1814 SpritePointMarker no longer draws upside down when used with a BubbleSeries
SCJS-1796 fixed dataPointWidth and yRange for candleStick series with a single candle
Fixed an error calculating labelWidth that could occur when using NativeText labels and doing lots of zoom/pan
Setting strokeThickness to 0 for candles and ohlc now applies correctly
SCJS-1825 fix autoRange for errorbars and candleSticks was wrong when using EDataPointWidthMode.Range
Worked around a new performance issue in Chrome which happens if the chart is invalidated very rapidly, eg by calling dataSeries.append/insert/update. It is still better to use appendRange where possible
Setting constructor options that take a NumberRange as { min, max } will no longer cause errors. This makes it possible to use pure json for definitions. THis also applies to a few other Object properties such as Thickness and Rect
Some minor fixes and documentation updates. Check out the new Line Splitting Thresholds Demo which uses a renderDataTransform to do precise coloring of partial line segments.
Canvas border was off by one if the canvas had fractional width or height
Add Typedoc and non-abstract base classes for renderDataTransform
Ensure renderDataTransforms run if resampled data changes
This release fixes some memory leaks that show up in some long running realtime scenarios, along with some other small fixes.
Fixed xRange calculation when using dataPointWidthMode.Range
SCJS-1797 Fixed a rendering issue on AMD GPU when using extreme zeroLineY
SCJS-1793 Fixed a memory leak in label text cache
SCJS-1793 Fixed a memory leak in WebGL buffers
If you have ever struggled to get sensible column widths if your data contains gaps, then dataPointWidthMode Range will help a lot. This makes the dataPointWidth be interpreted as "x range per column", rather than the width being based on the number of columns.
Now that we have getProperties on ColumnSeriesDrawingProvider, we have a good way to use different gradient fills for different columns. See the new multi-style series demo to see how to do this.
Also in this release are some memory related fixes and improvements. We recently added a whole section of additional memory tests and guidance to the examples repo. Please take a good look at https://github.com/ABTSoftware/SciChart.JS.Examples/tree/master/Tutorials/MemoryTests before reporting memory related issues.
Added dataPointWidthMode Range for columns, candlesticks and errorbars. This makes it much easier to set a sensible width if your data has gaps.
Add getProperties to ColumnSeriesDrawingProvider so multiple can be added to draw with different styles
Improved label cache pruning to improve memory behaviour, particularly when using native text
Fixed a memory leak when using Overview
DataPointSelection did not select all points in the shown area when using xyDirection: EXyDirection.XDirection
Fixed SmoothStackedMountainSeries builder api support
Along with a variety of little fixes, we have added SciChartHorizontalGroup which synchronises top and bottom axes. This is particularly useful if you have a set of vertical charts in a horizontal row. A surface can be added to both a SciChartHorizontalGroup and a SciChartVerticalGroup if you have a grid of charts and want both rows and columns to have synchronised axis sizes.
SciChartVerticalGroup and SciChartHorizontalGroup bot now also consider chart title
Added SciChartHorizontalGroup which synchronises top/bottom axis sizes
heatmap yAxisId option was setting XAxisId instead
Fix DataLabel positioning for band series when using singleLabel: true
Allow setting partial styles for ticks and gridlines in axis options
Avoid an error if legend is forced to update before the chart is drawn
Another round of various fixes. BandSeries now supports a vertical gradient fill (like MountainSeries), but be aware that the gradient is currently relative to the canvas, not the series, so it may not work the way you expect. MountainSeries gradients have worked this way for so long that at this point fixing this is considered a breaking change, so we will look to do it as part of the v4 release.
FillLinearGradient now supported on BandSeries
Pie chart was not showing if only one segment was defined
Fix error when calling sciChart3DSurface.renderableSeries.clear(true)
PointMarkerPaletteProvider was affecting the stroke of a mountain or band Series
Fix smooth stacked mountain series missing a point when the lower series contains NaN
Fix bezier transform not recalculating when visibleRange changes
Improved new Bezier line interpolation. Add XyyBezierRenderDataTransform for use with BandSeries
SCJS-1370 CursorModifier axis labels sometimes in the wrong chart when using subcharts
SCJS-1394 CursorModifier should not add extra labels on stacked axes
Various fixes for things we found when building the examples for the new features. Check out the new demos at demo.scichart.com
- Population Pyramid showing stacked column datalabels, and how to deal with overlaps from multiple series
- Smooth Animated Stacked Mountain Chart Our new series type, with cool in and out animations.
- Hoverable Buy Sell Markers is an upgrade to the existing trade markers demo with tooltips on hover.
- Editable Annotations also upgraded with hover features. More tooltips and select-on-hover
- Annotation Layers shows the options for placing annotations at behind the chart, behind the series, or in front.
- User Annotated Stock Chart has some custom modifiers for allowing users to add lines and markers to a chart, and demonstrates saving and loading those customisations.
Open up and add comments to methods on SmartDateLabelProvider to make it easier to customise further
Fix building dataFilters using builder api
Fix modifiers on subcharts not marking the original event handled, causing scroll to affect the parent page.
Fix error when calling includeSeries on a modifier before adding it to a surface
Added references to previously hovered entities and modifier in hover event args
Fix auto coloring for stacked mountain stroke
Fix startup animations not working for stacked series when passed as options.
SciChart.JS v3.4 - Hoverable Annotations, Stacked Series Improvements and much more!
We have a load of new features in this release, so we are bumping the minor version to 3.4. Documentation and examples to show off these new features are still being polished. We'll have a full release blog highlighting all the new features soon. For now, check out the hover behaviour we added to the trade markers example
AnnotationHoverModifier which enables onHover callback for annotations
DataLabels support for Stacked Column Series
BezierRenderDataTransform as for alternative line smoothing that stays within the data range
SmoothStackedMountainRenderableSeries which uses a the new Bezier smoothing
Startup animations (eg Scale, wave, sweep) can now be reversed
Startup animations now support onComplete callback
Individual series within a stacked collection can now be animated
Engineering formatting for axis and data labels. 1,000,000 -> 1M etc
Add option to completely disable the loader by setting loader:false in surface create
Non-Uniform heatmap support for CursorModifier
SVG Annotations will retain their z order when updated
ContourSeries now uses stroke color and thickness properly
Startup animations on spline series again properly apply the smoothing during the animation
SCJS-1693 Fixed that trying to render some extended characters would break native text rendering
SCJS-1754 workaround a browser issue where a canvas could be cleared when switching tabs
Several NaN related issues fixed in this release. We do our best to support them, but still advise you to avoid them if possible. If you need gaps in a series, consider using a paletteProvider and setting the color transparent.
Added PaletteFactory.createYGradient which takes a set of gradient stops and returns a paletteProvider which colours based on y value
You can now set indivdual parts of the sciChartSurface.padding and the chart will automatically redraw
Setting EAnnotationLayer.BelowChart on an svgAnnotation will now behave as foreground (the old behaviour) rather than throw an error
SCJS-1749 Fix seriesInfo equality check when data contains NaN, fixing continuous render when using rollover or cursor with NaNs
SCJS-1750 Add support for negative z values in Heatmap series
SCJS-1752 Fix line palleting is off by one if the dataSeries contains NaN
Some notable new features in this release. See the new annotation layer options in action in the new Annotation Layers demo. A demo of the new SmartDateLabelProvider features is coming soon.
Svg Annotations (including CustomAnnotation) can now be placed behind the chart using annotationLayer: EAnnotationLayer.Background
SS.ms Date formatting and automatic use of this in SmartDateLabelProvider
dateOffset added to SmartDateLabelProvider allowing for extremely high precision dates (with reduced range)
Animation support for series using renderDataTransforms
Fixed animations for spline chcarts would animate lines but not pointmarkers
Logarithmic axis now uses new autoRange: once detection properly
Two small but important fixes.
(0,10) is no longer a magic range that would cause autoRange: once to fire.
SCJS-1722 Charts with startup animations no longer display one frame of the final state at the start
Just a few little fixes and improvements in this release. Lots going on behind the scenes.
SJCS-1724 Fix crash with spline series if created with no data
SCJS-1715 Fix error if CursorModifier is used with a hitTestRadius on a heatmap
SCJS-1677 SciChartVerticalGroup now copies layoutStrategies when adding a surface, stopping it from overwriting custom strategies.
We are now publishing .mjs versions of the bundled version of scichart.js if you want to use it with ESM. This is somewhat experimental at the moment but we are working towards using this for pure js versions of our examples. You can get this via CDN using https://cdn.jsdelivr.net/npm/[email protected]/index.min.mjs
Experimental - bundle files built as ESM modules
Fix a potential error when navigating away from a page with a pie chart
Fixed a licensing issue where multiple wilddard domains were not handled properly
As well as some bug fixes, this release contains some low level features that allow for precise control of when a chart is drawn. Setting createSuspended: true in the surface options will cause the chart to be created in a suspended state where it will not automatically render. You can then await scichartSurface.nextStateRender which will resolve once the chart is fully drawn, which depending on the configuration may involve several frame renders. We have done this to improve the performance of our visual tests, but there are some other potential uses which we will show examples of soon.
We have also added a significant number of performance monitoring points, using the Web Performance API, to aid in identifying performance bottlenecks. Check out the PerformanceDebugHelper class for details.
More licensing flexibility for applications using IP addresses as host name
SCJS-1718 fix crash when using paletteProvider with spline series
SCJS-1717 Rollover and Cursor modifiers using modifierGroup did not work correctly with subcharts
rendered event now fires once chart image is copied to target canvas, so performance measurements based on prerender to rendered are more accurate
PerformanceDebugHelper and performance monitoring points
createSuspended option on SciChartSurface and nextStateRender to enable callbacks on first chart draw
Important release. Please update.
This release fixes an critical licensing issue affecting any application deployed with a 3.2 version of SciChart. All users need to update.
SCJS-1710 Fixed 6 month community expiry prevents runtime key being applied
Small release mainly to fix a bug with rollover/hittest when using FIFO sweeping mode.
We are starting a process of trying to reduce the webassembly data file size. Minor changes initially, but expect significant improvements in v4 coming soonish.
Removed some unnecessary assets from data file
SCJS 1596 expose dataSeries.FindIndex and fix some minor bugs there.
SCJS 1701 - HitTest is wrong for fifo sweeping
This release fixes the issue with candlestick charts crashing on Safari (due to a Safari quirk which we managed to work around).
Modifiers with multiple subcharts are now slightly easier thanks to isActiveSubChartEvent
DefaultPaletteProvider still had shouldUpdatePalette false. Default false until v4
Js/scjs 1628 Fixed candlestick charts crashing on safari
Added isActiveSubChartEvent flag to ModifierMouseArgs usefull for sub charts with a modifierGroup
Auto cleanup subscriptions in DataPointSelectionModifier
SCRTDoubleVector does not push_pack correctly for capacity 1
A final release for this year to fix a performance edge case and also to make the default behaviour of PaletteProvider consistent with what it was before the change in 5.3.8, which is to recalculate the palette on every render. To get the performance benefit of reuse on a static palette you need to add the shouldUpdatePalette method to your PaletteProvider and return false if the palette can be reused. We will be changing this default in version 4 to reuse if at all possible.
PaletteProvider now defaults to always recalculate for back compatability.
SCJS-1685 Improve performance when series is panned out of view
As well as some more fixes, this release includes the new RenderDataTransforms. This is a low level api that allows you to transform your data just before it is drawn. SciChart currently uses it to do spline interpolation, but it has the potential to support all kinds of cool features, like changing the color of a line between data points (by adding extra geometry), and applying multiple different line styles and pointMarkers to a single series. Expect more documentation, demos and features using this in 2024.
The PaletteProvider api has also been improved. Palettes can now be reused, with a property (isRangeIndependant) and a function (shouldUpdatePalette) to control when palette recalculation should occur. You can now even take full control of the palette by implementing IAdvancedPaletteProvider, which gives you a single function call for all the data rather than a call per point.
Added RenderDataTransform api and used it for spline series
Allow palettes to be reused if nothing has changed
Added isRangeIndependant and shouldUpdatePalette to IPaletteProvider to control palette reuse
New IAdvancedPaletteProvider interface. This is a single method called instead of the per-point overrides. Its parameters give you access to the full data and palette
SCJS-1768 Added yRangeMode property to renderableSeries and set the default on this to revert to previous behaviour where the points just outside the visibleRange will be included in autoRange. This fixes issues where digital lines were escaping the axis when used on stacked axes.
SCJS-1683 Annotation coordinateMode Relative now works correctly on a stacked axis
SCJS-1682 Fixed hitTest could be offset when using CategoryAxis
Fixes for recently reported bugs and a new demo. Check out Draggable Event Markers
SCJS-1669 Make rollover work for stacked charts with multiple axes

Progress on strict mode support
Fix types mismatch in getters and setters
Now that we have optional automatic webassembly disposal, deleting and creating a new chart could result in the creation of a new webassembly context. These fixes ean this will automatically get the license applied.
Make extra sure that the license will be applied if a new wasmcontext is being created
Fix license not reapplied if wasmcontext has been disposed
In 3.2 by default we clip the data that is sent to be drawn to what is actually visible. In some edge cases this might lead to undesired behaviour, so we've added axis.clipToXRange which allows you to disable this.
SCJS-1579 clipToXRange property to allow for disabling the new clipping to visibleRange for x axis
SCJS-1592 Partial fix for ring around pointmarkers with paletteProvider
SCJS-1591 AutoRange should use acutally visible data
