I am using a third party activex control to plot graphs. I am trying to make it so I can select points on the graph by clicking on them. However, the activex control has no implementation for this and gives me no methods that allow me to determine the location of the points on the graph.
The only way I can think of to get this to work is to determine if the color of the pixel in the spot I click matches the color that the activex control uses to draw the data points.
Thanks
