# chart.events.load

Fires when the chart is finished loading. Since v4.2.2, it also waits for images to be loaded, for example from point markers. One parameter, `event`, is passed to the function, containing common event information.

There is also a second parameter to the chart constructor where a callback function can be passed to be executed on chart.load.
