I'm attempting to get Plot coordinates in a vtkXYPlotActor. I am able to get viewport coordinates (ie: 0,0 = bottom left corner of the window), but I am at a loss on how to map those into coordinates of points in my xy Plot. I have attempted to use ViewportToPlot(), but that doesn't seem to work properly (or causes a seg fault). Any thoughts on this or examples? Am I missing a key element here?<br>
<br>Thanks,<br><br>Justin<br>
