[perl-win32-gui-users] need help with Graphic
I have a Graphic object that I am plotting data on. While the cursor is on this object I have a cross-hairs cursor. What I would like to do is extend lines from the cursor position to the edges of the graph (the perimeter) but not have them overwrite what is plotted there and as I move the cursor around the lines move accordingly. It would be the same effect as using a selection tool in any common paint program. I know how to track the current mouse position and i know the values for the boundaries of the graph; I just don't know how to produce the effect I am wanting. Has anyone ever accomplished this? Does anyone know HOW to do it? Any help would be greatly appreciated. Jonathan Jonathan Southwick [EMAIL PROTECTED] Technical & Network Services Allegheny College Meadville, PA 16335 (814) 332-2755

What I do is plot (x,y) the data points that I am graphing and connecting the points so that I have a line graph. Since I am plotting two series of data I have two different colored graphs.
