# Callbacks

# beforeRender

A callback that allows you to customize the underlying chart element before it is rendered. Use the highchartsOptions object that is passed to the callback to change options values (opens new window) and then return the modified options object. The returned options are then used when rendering the chart.

This callback is not supported for Indicator Chart, Areamap Chart, Scattermap Chart, and Table.

For an example of how the onBeforeRender callback can be used, see the Compose SDK Charts Guide.
