Im currently trying to rewrite an application that allows the user to select several data points by dragging the mouse over the chart area. Basically the user holds down the left mouse button, creates a rectangular area by dragging with the mouse, and anything inside that area will be selected. Does radviewchart support something like this? I'm looking for something analogous to Dundas chart's selectionrangechanging event. Sorry if there's an obvious answer here, I just started using telerik yesterday. Thanks.
