The following example uses the ASPxDasard's client-side API to obtain client data that corresponds to a particular visual element.
The ASPxClientDasard.ItemClick event is handled to obtain client data and invoke the dxPopup component with the dxChart.
In the event handler, the e.GetData method is called to obtain dasard item's client data. The e.GetAxisPoint method returns the axis point corresponding to the clicked card while the ASPxClientDasardItemData.GetSlice method returns the slice of client data by this axis point.
The ASPxClientDasardItemDataAxis.GetPoints method is used to obtain axis points that belongs to the "Sparkline" data axis. Corresponding actual/target values are obtained using the ASPxClientDasardItemData.GetDeltaValue method.
When you click a card, the dxChart displays the detailed chart and shows a variation of actual/target values over time.
