Hello all,
I would like to be able to plot my data point after point, in two
graphs. So, point1 in graph1, point1 in graph2, point2 in graph1,
point2 in graph2 etc., in one window. Is there a way to switch back
and forth between the several graphs on a window?
If anyone knows and is willing to tell me, thanks in advance.

Thanks a lot; this works very well. Also thanks to the people who
responded to me by e-mail.
