Class: AccessibilityComponent

Highcharts. AccessibilityComponent

new AccessibilityComponent()

The AccessibilityComponent base class, representing a part of the chart that has accessibility logic connected to it. This class can be inherited from to create a custom accessibility component for a chart.

Components should take care to destroy added elements and unregister event handlers on destroy. This is handled automatically if using this.addEvent and this.createElement.
