Remarks

An end-user is able to hot-track some items of the ASPxClientWebChartControl at runtime if the WebChartControl.EnableClientSideAPI property is set to true. Handle the ObjectHotTracked event if you want to perform some specific actions when an end-user hot-tracks a chart’s elements, or if you want to disable the hot-tracking of particular elements. Note that the currently hot-tracked element of the chart can be accessed via the ASPxClientWebChartControlHotTrackEventArgs.hitObject and ASPxClientWebChartControlHotTrackEventArgs.additionalHitObject properties.
