Fixed

• Export: Invoking export's getSVG() method without passing in options as a second parameter was resulting in error.
• Series' actual value was not being properly updated in all cases when used with gropuDataItem adapter.

Changed

4.10.4

[4.10.4] - 2020-09-22

Changed

• Accessibility: ExportMenu will now set aria-expanded attributes for selected menu items/branches.

Fixed

• Toggling a legend item was adding a hidden element outside chart container area, which was sometimes causing scrollbars to appear on the web page.
• Toggling rtl value on an existing Label was not working properly.
• Accessibility: setting rederTitle or itemReaderTitle was not setting aria-label but rather adding <desc> tag and aria-describedby attirubute. It now will use aria-label for readerTitle and <desc> for readerDescription.

4.10.2

[4.10.2] - 2020-09-08

Fixed

4.10.1

[4.10.1] - 2020-09-07

Added

• New DateAxis property: timezone. Allows setting timezone to recalculate data in, e.g. "Australia/Sydney". Make sure not to set this on both axis and date formatter.

• In some cases a heat rule could result in infinity value which would lead to drawing errors.
• Errors when cloning a RadarChart from a template fixed.

Added

• New LineSeries property: smoothing ("bezier" (default), "monotoneX", and "monotoneY") - indicates algorithm to use for smoothing the lines. Monotone algos are better suited for irregularly-spaced data. More info.
• ForcedDirectedTree: new property zoomable (default: false). If set to true, the chart will be zoomable/draggable using mouse, touch, or API. More information.
• ForcedDirectedTree: zoom related properties added. mouseWheelBehavior ("zoom", "none") - controls what happens when mouse wheel is used over chart; zoomStep (default: 2) - step to increase zoom level my each zoom in; zoomOutButton - an instance of button which is shown when chart is zoomed in.
• ForcedDirectedTree: new zoom-related methods: zoomToPoint(point, level, center) and zoomToDataItem(dataItem, level, center);
• New global function: am4core.createDeferred(callback, scope, ...parameters). Can be used to create multiple charts in a truly safe daisy-chain (next chart starts to be instantiated only when previous triggers a ready event). Returns a Promise with chart instance. More information;
