Here is a suggestion that should get you started with this task. You can wrap the chart within a Canvas and handle Canvas.MouseLeftButtonUp
event. Its event args will provide the coordinates of the point clicked, so that you can draw a vertical line -- within the canvas, on top of the chart. In addition, you can subscribe to ChartArea.PlotAraeMouseLeftButtonUp
event. Its event arguments (PlotAreaMouseEventArgs
) will hold the XValue and YValue of the point clicked. Having the XValue should allow you to look into the ChartSeries and find the corresponding YValues for each series.
