4.9.26

[4.9.26] - 2020-06-07

Fixed

• Series with showOnInit = false were not shown on a chart initially (since last release only).

4.9.25

[4.9.25] - 2020-06-06

Added

• Global option am4core.options.autoDispose added (default false). If set to true, when chart is being created in a container that has already existing chart, instead of "Chart was not disposed" warning in console, the chart being overwritten will be disposed.
• New plugin: Range Selector. Collection of controls for adding alternative zoom controls for axes.

Changed

• Disabled callbacks will now carry over to a clone when cloning an Adapter.

Fixed

• Export: Sometimes background was improperly clipped when upscaling exported image.
• Export: If chart's data was updated open ExportMenu was forcibly being closed.
• "Z" and "ZZ" indicators in inputDateFormat were being ignored.
• If series had sequencedInterpolation = true set and it was hidden via legend, its legend item lost disabled color when chart was resized.
• bullet.locationX and bullet.locationY was being ignored on a ColumnSeries with CategoryAxis.
• If a chart's Legend was disposed, it could result in JS errors if chart had an XYCursor enabled.

4.9.24

[4.9.24] - 2020-05-29

Added

• Export: New image export options: minWidth, minHeight, maxWidth, and maxHeight. Control minimum and maximum dimensions of the target image.
• Chart can now be initialized without target container (am4core.create(undefined, ...)) then, when needed placed into container using chart.moveHtmlContainer(target) (where target can either be id or a reference of DOM element).
• groupInterval property added to DateAxis. You can use it to force certain grouping internal when groupData = true instead of one chosen dynamically.

Changed

• stroke/fill settings will now accept values as RGB objects (e.g.: { r: 255, g: 0, b: 0 }).
• Export: scale now scales source SVG before converting to image, instead of resampling target image.
• Chart will no longer error out if target container by supplied id is not available at the moment of chart's instantiation. It will still error if such container is not available when DOM is ready. This allows placing chart code before actual chart target markup.
• If Axis has syncWithAxis = true set, it is excluded from common zoom range for better syncing.

Fixed

• Sometimes responsive rules were not being applied on chart load in Angular apps.
• XYCursor setting snapToSeries now uses better precision in placing cursor lines/axis tooltips.

4.9.23

[4.9.23] - 2020-05-19

Added

• removedfromqueue event added to Sprite. It is invoked when am4core.options.queue = true or am4core.options.onlyShowOnViewport = true and the Sprite (chart) is removed from queue (appears on the screen).
• groupperiodchanged event added to DateAxis. It is invoked when data grouping is on and grouping period is changed.

Fixed

• JSON: Array value in snapToSeries on XYCursor was resulting in error.
• RadarChart was resulting in an error if used as a column or bullet template in some other chart.
• AxisRendererRadial.innerRadius was ignored if set in percent and RadarChart.innerRadius was not set.
• Wide charts were being cut off in the middle when printing.

4.9.22

[4.9.22] - 2020-05-14

Changed

• Export: Now using forked version of canvg until underlying issues are fixed in source library.

Fixed

• queue and onlyShowOnViewport were not working properly on regular Container instances.
• Export: Garbled IE image exports fixed.
• Some tooltips were reappearing on MapChart after their showToolipOn was reset back to "hover" from "always".

4.9.21

[4.9.21] - 2020-05-13

Fixed

• Latest version of canvg was causing issues in some Angular setups. Downgraded to 3.0.0.
• The legend marker for LineSeries with circle bullet was not properly centered.

4.9.20

[4.9.20] - 2020-05-11

Changed

• hit and up events on nested objects will now respect correct bubbling up order.
• If rtl is not set directly on the Label, it will now take rtl value not from its parent but from baseSprite (performance enhancement).
• <desc> element with amCharts attribution removed from generated SVG.

Fixed

• Export: PDF export will now fallback to regular fonts if bold fonts don't exist.
• Export: Advanced PDF exports with extra content were broken since last release.
• Export: Image export was essentially broken in IEs.
• options.nonce was not working properly on EDGE.
• Event selectedned was not dispatched by Cursor if released outside the chart div and behavior was set to select*.
• If all series were removed and then added quickly to the chart with a legend it could result a JS error.
• Setting data directly on a series not right after it was created could result series.data array to be shown as empty.
• It was impossible to set SwitchButton as active initially.
• Fixed snapping cursor to series when data was missing: if series had gaps in data and cursor.snapToSeries was set, the snapping was not working properly.
• When adding data to XYSeries which was XYCharScrollbar's series, the raw data was incorrectly modified.

4.9.19

[4.9.19] - 2020-04-30

Added

• Export: Two new PDF export options added: font and extraFonts which enable specifying non-default font to use when exporting PDF. More info.

Changed

• Third party resize sensor replaced with a home-brewed, which is faster and more reliable.
• svgContainer.resizeSensor replaced with a dummy object. Make sure you remove all references to it in your code. Calling it's reset() method will now generate a warning in console.

Fixed

• Inline text formatting blocks now accept quote-enclosed values, e.g. [font-family: 'Segoe UI'].
• Fills for columns in RadarColumnSeries were black (since last release).
• With Chrome 81 disposing the chart in with DevTools open was very slow.
• Performance optimizations when showing/hiding series with a lot of data.
• Tooltip was flickering at 0,0 position if animated theme was not enabled.

4.9.18

[4.9.18] - 2020-04-28

Added

• Heatmaps can now be logarithmic (set logarithmic = true in the heat rule config).

Fixed

• Preloader label was misaligned when RTL was enabled.
• Double "hit" event invocation on MapPolygon fixed.
• Regression plugin: "processed" event was triggered twice on initial chart load.
• SliceGrouper plugin: if slice templats had any "hit" events set, clickBehavior = "break" was not working.
• IE was not displaying series in XYChartScrollbar. On IE now gray fill/stroke is used instead of desaturate filter.
• IE was not displaying series with filters. Remnoved filters if IE.
• Fixed issue with zero-value nodes drill-down SankeyDiagram.
• When animations were disabled through options, showing XYSeries and FunnelSeries after it was hidden was not working.
• It was not possible to add MapImages to MapImageSeries directly from the GeoJSON geodata.
• maxWidth set on Legend's label was being ignored.
• Layout was not being redrawn when minGridDistance was set after chart initialization.
• If sprite.showTooltipOn = "hit" and no animated theme was used, tooltip used to flicker at old position before shown in the correct one.
• EDGE was not showing ColumnSeries gradients if gradient was set on series, not on directly on column template.

4.9.17

[4.9.17] - 2020-04-20

Added

• Global option am4core.options.nonce added. If set, amCharts will use this as a nonce-parameter for all dynamically created stylesheets, so it can be addressed in Content-Security-Policy headers.
• New Popup property: dynamicResize. If set to true (default) and contents contains unloaded images it will resize itself when those finish loading.
• gradientUnits added to LinearGradient. If you're setting gradient on a perfectly straight line, set it to userSpaceOnUse.
• filterUnits added to Filter. If you're setting gradient on a perfectly straight line, set it to userSpaceOnUse.
• startLocation and endLocation added to CategoryAxisBreak. Can use to indicate where exactly within category break should start and end.

Changed

• Popup now will size itself to accommodate images inside it as they are being loaded. To disable, set Popup's dynamicResize = false. Also make sure you enable maxWidth/maxHeight in your CSS to avoid unreasonably large popups for unsized images.

Fixed

• Week number in date format ("ww") was not accounting for daylight saving.
• Pressing ENTER on a focused Legend item will no longer toggle related series if legend's item containers are sett to be not togglable.
• Exporting to SVG no longer breaks if chart contains foreignObject elements with SVG's in them.
• Line smoothing (tensionX / tensionY) now drops out duplicate points to avoid weird loops on overlapping data items.
• Chart was zooming incorrectly, when data was added directly to stacked series and one of the series was hidden.
• Some performance issues with XYCursor and a lot of series fixed.
• LinearGradient fill was not working on LineSeries under EDGE.
