Thanks to all those of you who answered my question about how to save a plot
to a file.
But now I have another problem. That is I wish to see / examine the plot on
the screen in advance of saving it to a file. If I launch X11() or pdf() or
Poscript() the plot does not appear on my screen .. So I have to save it
blindly ??

Thank you again
