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

Added

AnnotationHoverModifier which enables onHover callback for annotations

Added

DataLabels support for Stacked Column Series

Added

BezierRenderDataTransform as for alternative line smoothing that stays within the data range

Added

SmoothStackedMountainRenderableSeries which uses a the new Bezier smoothing

Added

Startup animations (eg Scale, wave, sweep) can now be reversed

Added

Startup animations now support onComplete callback

Added

Individual series within a stacked collection can now be animated

Added

Engineering formatting for axis and data labels. 1,000,000 -> 1M etc

Added

Add option to completely disable the loader by setting loader:false in surface create

Added

Non-Uniform heatmap support for CursorModifier

Improved

SVG Annotations will retain their z order when updated

Fixed

ContourSeries now uses stroke color and thickness properly

Fixed

Startup animations on spline series again properly apply the smoothing during the animation

Fixed

SCJS-1693 Fixed that trying to render some extended characters would break native text rendering

Fixed

SCJS-1754 workaround a browser issue where a canvas could be cleared when switching tabs

3.3.592
20 May 2024

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

Added PaletteFactory.createYGradient which takes a set of gradient stops and returns a paletteProvider which colours based on y value

Improved

You can now set indivdual parts of the sciChartSurface.padding and the chart will automatically redraw

Improved

Setting EAnnotationLayer.BelowChart on an svgAnnotation will now behave as foreground (the old behaviour) rather than throw an error

Fixed

SCJS-1749 Fix seriesInfo equality check when data contains NaN, fixing continuous render when using rollover or cursor with NaNs

Improved

SCJS-1750 Add support for negative z values in Heatmap series

Fixed

SCJS-1752 Fix line palleting is off by one if the dataSeries contains NaN

3.3.586
3 May 2024

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.

Added

Svg Annotations (including CustomAnnotation) can now be placed behind the chart using annotationLayer: EAnnotationLayer.Background

Added

SS.ms Date formatting and automatic use of this in SmartDateLabelProvider

Added

dateOffset added to SmartDateLabelProvider allowing for extremely high precision dates (with reduced range)

Added

Animation support for series using renderDataTransforms

Fixed

Fixed animations for spline chcarts would animate lines but not pointmarkers

Fixed

Logarithmic axis now uses new autoRange: once detection properly

3.3.577
9 April 2024

Two small but important fixes.

Improved

(0,10) is no longer a magic range that would cause autoRange: once to fire.

Fixed

SCJS-1722 Charts with startup animations no longer display one frame of the final state at the start

3.3.575
18 March 2024

Just a few little fixes and improvements in this release. Lots going on behind the scenes.

Fixed

SJCS-1724 Fix crash with spline series if created with no data

Fixed

SCJS-1715 Fix error if CursorModifier is used with a hitTestRadius on a heatmap

Improved

SCJS-1677 SciChartVerticalGroup now copies layoutStrategies when adding a surface, stopping it from overwriting custom strategies.

3.3.570
28 February 2024

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

Added

Experimental - bundle files built as ESM modules

Fixed

Fix a potential error when navigating away from a page with a pie chart

Fixed

Fixed a licensing issue where multiple wilddard domains were not handled properly

3.3.567
12 February 2024

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.

Added

More licensing flexibility for applications using IP addresses as host name

Fixed

SCJS-1718 fix crash when using paletteProvider with spline series

Fixed

SCJS-1717 Rollover and Cursor modifiers using modifierGroup did not work correctly with subcharts

Improved

rendered event now fires once chart image is copied to target canvas, so performance measurements based on prerender to rendered are more accurate

Added

PerformanceDebugHelper and performance monitoring points

Added

createSuspended option on SciChartSurface and nextStateRender to enable callbacks on first chart draw

3.3.560
29 January 2024

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.

Fixed

SCJS-1710 Fixed 6 month community expiry prevents runtime key being applied

3.2.555
18 January 2024

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.

Improved

Removed some unnecessary assets from data file

Improved

SCJS 1596 expose dataSeries.FindIndex and fix some minor bugs there.

Fixed

SCJS 1701 - HitTest is wrong for fifo sweeping

3.2.549
8 January 2024

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

Fixed

DefaultPaletteProvider still had shouldUpdatePalette false. Default false until v4

Fixed

Js/scjs 1628 Fixed candlestick charts crashing on safari

Added

Added isActiveSubChartEvent flag to ModifierMouseArgs usefull for sub charts with a modifierGroup

Fixed

Auto cleanup subscriptions in DataPointSelectionModifier

Fixed

SCRTDoubleVector does not push_pack correctly for capacity 1

3.2.543
21 December 2023

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.

Updated

PaletteProvider now defaults to always recalculate for back compatability.

Improved

SCJS-1685 Improve performance when series is panned out of view

3.2.538
15 December 2023

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

Added RenderDataTransform api and used it for spline series

Improved

Allow palettes to be reused if nothing has changed

Added

Added isRangeIndependant and shouldUpdatePalette to IPaletteProvider to control palette reuse

Added

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

Improved

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.

Fixed

SCJS-1683 Annotation coordinateMode Relative now works correctly on a stacked axis

Fixed

SCJS-1682 Fixed hitTest could be offset when using CategoryAxis

3.2.532
