RadHtmlChart provides several client-side events, the handlers to which can be attached through the control's
ClientEvents inner tag:
OnLoad — fires when the control is initialized.
OnSeriesHovered — fires when a series is hovered.
OnSeriesClicked — fires when a series is clicked.
OnLegendItemHovered — fires when a legend item is hovered.
OnLegendItemClicked — fires when a legend item is clicked.
All client-side events, except OnLoad, are references to their corresponding events of the
Kendo UI HtmlChart object. You can get familiar with the full set of arguments coming with each event
in the Kendo UI HtmlChart API reference.
