Thanks for your reply. I am sorry, but I am really new at Mathematica, and when I exactly copied what you produced (the example you made) I got this error message:
Show::gtype: Symbol is not a type of graphics.
Is there any wrong with the Mathematica I used or with what I copied?
Thanks again.
(I got 2 packages on this from two different people, but I also want to try what you made).
Sincerely,
Jose Capco
