symbols property

List<String>? symbols
getter/setter pair

Array to define shapes of handles. 0-index for left, 1-index for right.

Additionally, the URL to a graphic can be given on this form: url(graphic.png). Note that for the image to be applied to exported charts, its URL needs to be accessible by the export server.

Custom callbacks for symbol path generation can also be added to Highcharts.SVGRenderer.prototype.symbols. The callback is then used by its method name, as shown in the demo.
