I am afraid that just write with poor English.
I want to draw a series by the mouse left button click.
1) Mouse left click to get the Point form the chart and the Point’s value is relation with x,y axes that don’t relation with screen point.
2) Add the getting Point to the series ‘s DataPoint
So,how can I get the point that value relation with x,y axes from the chart?

see the "Mouse events > LineSeries and PlotModel MouseDown event" example in the example browser, I think that one does exactly what you need.
