These pages outline the chart configuration options, and the methods and properties of Highcharts objects.
Feel free to search this API through the search bar or the navigation tree in the sidebar.
A text description of the chart.
Note: Prefer using caption instead.
If the Accessibility module is loaded, this option is included by default as a long description of the chart in the hidden screen reader information region.
Note: Since Highcharts now supports captions, it is preferred to define the description there, as the caption benefits all users. The caption will be available to screen reader users. If this option is defined instead, the caption is hidden from screen reader users.
