The following example demonstrates how to get client data corresponding to a particular visual element using DashboardViewer's API.
In this example, the DashboardViewer.DashboardItemClick event is handled to obtain client data for the Card dashboard item and display this data in a Chart control. We obtain axis points placed on the "Sparkline" axis for the clicked card, determine corresponding actual/target values, and save these values to a data table. This table is used as a data source for the Chart control.
