PlotMouseDown Event

This event is generated whenever the user positions the mouse over the plot area and presses down on its left, right, or middle button. Refer to Chart Overview for an illustration of XY Chart NET's major components.

If Y-Stacking is being used, the chart will display more than one plot area. In this case, a PlotMouseDown event will not be raised if the mouse is positioned and then pressed over the gap between the plots.
