Version 5.0.211 has been promoted to 5.1.0
Just six weeks after the release of SciChart.js v5.0 we have another minor update for you. Our pace of development has increased dramatically and the features & fixes below are just a fraction of what we’ve been working on in the last month – there’s a lot more on the way.
Blazor Support is now official. See SciChart.Blazor.Examples. This is an initial alpha release, and there are more features to come, but please send us your feedback.
It’s recommended for all users of SciChart.js v5 to update to this version, and keep watching the changelog as we roll out improvements in the coming weeks & months.
Added SciChart.Blazor — SciChart.js is now available as a Blazor component package for .NET/Blazor applications.
Pie/Donut chart rounded corners — Pie and donut chart segments now support configurable corner radius for a modern appearance. (SCJS-2394)
3D XYZ metadata API — XyzDataSeries3D now supports setMetadata() and setMetadataAt(), allowing per-point metadata to be updated and trigger chart invalidation correctly. (SCJS-2405)
Native text for modifier axis labels — When useNativeText is enabled, modifier axis labels (e.g. cursor/rollover crosshair labels) now render using the same native text path as axis labels, so font families match exactly. (SCJS-2440)
Overview control with stacked series — Fixed an issue where stacked chart collections were not correctly mapped to the Overview chart control. (SCJS-2445)
DataPointSelectionModifier — Fixed drag-selection not including the last data point in the selection range. (SCJS-2412)
Canvas labels missing on first render — Fixed an issue where canvas-rendered axis labels did not appear on the initial render.
SubChart modifiers — Fixed chart modifiers on sub-charts not being updated after a layout complete event. (SCJS-2431)
Stacked series negative values — Fixed stacked column and mountain series not correctly accumulating negative values. Hit-testing and 100% stacked autorange are also corrected. (SCJS-1740)
DateTimeNumericAxis tick precision — Fixed DateTimeNumericAxis generating poor tick values at sub-second precisions (e.g. showing 876ms, 939ms instead of 800ms, 900ms). (SCJS-2408)
Polar axis label positioning — Fixed polar axis labels overlapping at certain configurations, and fixed incorrect horizontal positioning of labels on vertical axes. (SCJS-2439)
Polar angular labels — Fixed the last angular label being omitted when the polar chart is rotated.
Mountain series clamping — Fixed forceClamp not being passed through correctly for mountain series, causing incorrect rendering near axis edges.
Tooltip positioning — Fixed tooltips being positioned incorrectly on the first render frame.
Duplicate destination IDs — Fixed an error when deleting a surface destination that shares an ID with another. (SCJS-2242)
Axis renderer optimisations — Reduced redundant work during axis measurement and label rendering for improved frame throughput.
Label cache pruning — Improved performance when using many charts simultaneously by refining how frequently the label cache is pruned, using a minAge threshold to avoid excessive pruning overhead.
Label cache memory leaks — Fixed multiple memory leaks relating to the label cache: canvas texture handles were not being released, and intermediate minMax calculation results were not disposed. (SCJS-2407)
PolarAxisRenderer memory leak — Fixed a memory leak in the polar axis renderer; the old renderer is now properly deleted when the axis type changes. (SCJS-2444)
This is a hotfix for v4, fixing some label related issues. Some of these are already addressed in v5 but the next v5 release will include a more significant refactor of label drawing to further improve performance and extensibility.
Fixed labelCache related errors when using multiple createSingleCharts
Fixed "Cannot read properties of undefined (reading 'measureText')" causing axis labels to not display in some rare cases
Fixed positioning of heatmap datalabels in some configurations
Fixing some early bugs in 5.0 including points being wrongly repositioned when panning a chart.
Fixed Heatmap dataLabel positioning
Prevent a chart freeze due to infinite loop
Second and penultimate points could be wrongly adjusted by viewport clamping when panning

We had another go at the rollover tooltip positioning algorithm, which now properly handles cases where you have multiple clusters of series. We also fixed a small memory leak.
5.0 beta should be up any day, with full release by the end of January.
Fixed a slow memory leak related to native text
Made the rollover modifier tooltip batching more reliable
This release fixes a rare bug that can occur with long running apps using serverside licensing. To do this, we backported some significant license handling changes we had done for the next big release, which significantly improves how license updates are propagated to surfaces. This also allows license validation to be triggered without creating a surface by calling getSharedWasmContext().
We have decided that the next big release will be 5.0 rather than 4.1 as there are a few potential breaking changes. We are hoping to have this out before the end of the year as we are very excited to share all the performance improvements we have made.
Allow license validation to be be triggered without needing to create a surface. Just call getSharedWasmContext()
Serverside token revalidation was not happening after 7 days, causing charts to become copies of the master canvas if the app ran continuously
Reworked client side license handling to not hold and surface references, fixing potential memory leaks
Just one bugfix in this release. All work is now focussed on 4.1.
SCJS-2304 Fix error when some modifiers are removed from a chart
Along with some bug fixes and mini features needed for our new demos Semiconductors Dashboard and Wafer Analysis Chart, this release contains a number of internal changes in preparation for performance comparisons with the upcoming 4.1 release, which will have a wide range of significant performance improvements. We will also be showing how you can use these marks to profile SciChart performance in your own applications. Watch this space!
Added lots of internal performance marks
SCJS-2289 Do not error if hitTestRadius used with StackedColumnSeries
Made overview surface available to series transform function
If you ran out of memory when appending data, the error used to be swallowed. This is now rethrown with a more helpful message

Allow hitTestRadius to be configurable on DataPointSelectionModifier
Open up the api on DataPointSelectionModifier so it is easy to programatically manage the selection
Tooltips in 3D could be offset when used with large surface mesh
If you are using your own images with SpritePointMarker, setting the new antiAlias property false should make it draw in its original form, rather than antiAliased. We have also made further improvements to stacked series as a result of some big new demos we have been working on. Also some bug fixes, noteably superscript (needed for scientific notation labels) now works properly for native text.
SCJS-2225 Added antiAlias property to PointMarker which can be disabled to produce sharper drawing when using custom sprites
SCJS-2246 Added autoColorFilter to SciChartSurface. This is a filter funciton to determine which renderableSeries are affected by AutoColoring, eg to apply only to visible series
SCJS-1923 DataPointSelectionModifier and SeriesSelectionModifier can now be used with Stacked series
Support seriesName and yArrayFilter as constructor options for stacked series

SCJS-2212 fix Heatmaps on vertical chart
Show license error on 3d chart if license is 2d only
vectorToArray and vectorToArrayView utility functions allow for for fast conversion of dataSeries xValues, yValues into JS arrays. This enables fast read-back of DataSeries data into javascript arrays, (unsafe) live-updating of webassembly memory via JavaScript, and fast deep-copy of dataseries.
See https://www.scichart.com/documentation/js/v4/2d-charts/chart-types/data-series-api/get-set-value-at-index/ for further info, benefits, performance & caveats
vectorToArray and vectorToArrayView utility functions for fast conversion SCRTVectors into JS arrays
SCJS-2207 RolloverModifier does not draw tooltips for CategoryAxis
This release contains a security fix for one of our dependencies, a new feature for legends for 3D charts, some significant improvements to the ContoursSeries behaviour, fixes for NativeTextAnnotation, and fixes for some more regression bugs.

SCJS-2201 Fixed error when appending large amount of data to an XyTextDataSeries
SCJS-2163 NativeTextAnnotation positioning and adorner size no longer ignores padding
Allowed adding a CursorModifier to a chart containing contour series. This now has the same hitTest behaviour as Heatmap series, so if you have both, use includeSeries to target the modifier at just one.
Fixed DataLabel positioning for contours
Fixed zMin, zMax and zOffset not behaving as expected for ContourSeries
Updating isVisible for 3D series now works as expected
LegendModifier3D - Legends for 3D charts with the same api and functionality as for 2D

SCJS-2059 RolloverModifier Tooltips do not hide for FastBandRenderableSeries
Adds the ability to override UniformHeatmapDrawingProvider and UniformContoursDrawingProvider createPaletteTexture() methods which allows creating stepped heatmaps (heatmap without a gradient) by creating a custom drawing provider.
SCJS-2041 Exposing UniformHeatmapDrawingProvider and UniformContoursDrawingProvider createPaletteTexture() methods
Fix for error when re-attaching FastBandRenderableSeries.
SCJS-2040 Error when reattaching FastBandRenderableSeries
Memory leak fix for WebGlRenderContext2D.drawLines() method.
SCJS-2036 WebGlRenderContext2D.drawLines() method leaks the memory
Fix for RolloverModifier overlapping tooltips.
SCJS-2032 Fixed RolloverModifier overlapping tooltips. Bug introduced in 3.5.739
This release introduces WebGlRenderContext2D.drawNativeText() API which can be used to draw text in a performant way. The API can be used for creating custom annotations or for direct drawing. The release also contains some fixes and improvements.
SCJS-2035 WebGlRenderContext2D.drawNativeText() API to draw text in a performant way
SCJS-2034 Improved getYRange() method for FastErrorBarsRenderableSeries with NaN data
Fixed switching between 2D and 3D charts. The bug was introduced in 3.5.750
SCJS-2006 Improved RolloverModifier performance with a large number of excluded series
This release rolls back line annotation label drawing performance optimizations. These changes were causing line annotation labels not updating correctly.
Fixed line annotation labels not updating correctly.
In SciChart3D, the “gizmo” is the x/y/z direction indicator in the bottom left of the chart. This was always shown, because apparently the code to disable it was bugged. This is now fixed so the gizmo is disabled by default. To get it back, call sciChart3DSurface.enableGizmo(true)
Fixed spline errors if series only has one point
Fixed that sciChart3DSurface.enableGizmo(false) did not disable the gizmo. Set this disabled by default
Improved performance of line annotation label drawing
This release contains an important fix to an issue introduced in 3.5.739 which caused lines and pointmarkers with paletteProviders to have random colors when zoomed or panned.
SCJS-1960 Correct handling of palette offsets when zoom/panning non-resampled data
A small release to fix a licensing issue when using serverside licensing with 2d and 3d charts together.
Note that we recently released an update to the serverside component so that it now supports MacOS as the server.
Fixed ServerSide licensing not working correctly when 2D and 3D charts are used together
Edit 2025-03-19 – this release introduced a rendering bug which is fixed in v3.5.744
Along with some small fixes, this release significantly improves the performance tracing options in SciChart. This is partly to allow us to do detailed performance analysis and comparison in the upcoming v4, and also to allow users to more easily find the source of performance issues in their charts. More details on how to use this will be published later. As part of this we added some extra events to the render loop to allow for more accurate measurement, especially when subcharts are used. These events also give users an opportunity to add completely custom drawing into the render loop. The render events are as follows:
– preRenderAll: fires once on a parent surface before anything is drawn.
– preRender: fires at the start of rendering for each surface and subsurface.
– genericAnimationsRun: fires early in rendering once all animations have been processed. At this point the data for the render is set.
– layoutMeasured: fires once axis measurement and layout is complete. At this point the seriesViewRect and coordinateCalculators are valid, so you can use the hitTest api, and reposition annotations. If you do make changes to the chart here, use SuspendUpdates so that your changes do not trigger an unnecessary extra render. It is important not to change data, visible range or other layout related properties at this stage.
– rendered: fires at the end of the render loop for each chart and subchart. Note that actual drawing may not have happened yet.
– renderedToWebGl: fires once WebGL drawing has been complete. At this point you can still use the currentWebGlRenderContext to do custom drawing which will go over whatever scichart has drawn.
– renderedToDestination: fires once the chart has been drawn to the final target canvas. When SciChartSurface.createSingle is used, this is the same as renderedToWebGl, but for SciChartSurface.create there is a canvas copy in between. At this point, SciChart is completely done and you can draw to the target canvas using the 2d canvas context, which you can get from sciChartSurface.domCanvas2D.getContext(“2d”);
Various fixes and improvements to the events fired during render. Added preRender and rendered for 3D charts
Added many more marks to PerformanceDebugHelper
SCJS-1902 Improved memory and performance when rapidly updating large numbers of subcharts
SCJS-1936 Fix SVG Annotation drawing issues in Firefox
Fixed Rollover tooltip layout could be bad in some multi-series cases
SCJS-1916 allow overriding padding of labels on LineAnnotation
SCJS-1946 fix palleting repeating when drawing very large non-resampled data
Added fixes for AxisDragModifier, as well as a performance boost via freezeWhenOutOfView flag and improved performance in Mozilla based browsers
SCJS-1895 Added freezeWhenOutOfView flag to SciChartSurfaceBase. When true, charts out of the viewport will automatically suspend drawing. Major performance boost in multi-chart scenarios where some charts are out of view.
SCJS-1383 Improved Mozilla performance by up to 300% by optimizing canvas draw calls
SCJS-1896 Fixed UpdateSuspender cleanup logic affecting createSuspended flag in SciChartSurface
SCJS-1886 AxisDragModifier now respects visibleRangeSizeLimit
SCJS-1886 AxisDragModifier respects dragging top/bottom half in Vertically Stacked Axis scenarios
Along with some small fixes, this release has a fairly large toolchain update, setting us up for future improvements.
SCJS-1882 fixed y autoRange with category data. Force recalc of ranges when series made visible or attached.
Bezier transform was inconsistent with only one point in view
SCJS-1876 RubberBandZoom does not respect visibleRangeLimit
Updated builds to use recent emscritpen
Avoiding unnecessary re-measuring of svg has made re-rendering of TextAnnotation and CustomAnnotation about 100 times faster. Creating a large amount of svg is still slow (300ms for the first frame for 1000 annotations) but subsequent frames are now 10ms when zooming and panning.
Note that 3.5.710 got released in error with a regression for TextAnnotation adorners, so do not use that version.
Huge performance improvement for re-rendering most svg annotations
SCJS-1872 fix error on hitTest when using non-default dataPointWidthMode
We did not like the previous change to range limits with the overview, and we think this release does it much better. The behaviour is now that the overview x axis takes the full x range, and any visibleRangeLimit or visibleRangeSizeLimit on the main chart is applied to the selected area of the overview. If you want to limit the overview x axis you can pass limits on the overviewXAxisOptions.
We have also improved the handling of custom fonts in 3d so you can now use registerFont as described in the Native Text Api Documentation
Overview now properly works with visibleRangeLimit and visibleRangeSizeLimit
Added registerFont method to Scichart3DSurface.
Improved error handling during 3D rendering
fontFamily can now be set on 3D axis constructor option
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/scichart@3.3.570/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.

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

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
