 	Since you are the one who ported PLPLOT and enhanced it for the
Amiga, you should be blowing your horn! You have done an excellent job..

Now for some questions, since I'm working on my front-end for it.:

- How can you change the size of the printed graph from within the
 program using PLPLOT? Right now the only way I can figure is to size
 the window, do an IFF save, and load it into a paint program to print
 it out. Another kludge is to go into prefs and play with the pixel limits
 for the printer. Also, the print options that say (landscape) and 
 (portrait) end up printing tiny. Can this be adjusted? Right now I am
 just using the bitmap dump. 

- When clearing a current plot to do a new one, I end up having to click
  the close gadget on the current plot window before the new one comes
  up. Is there a way to automate this?

- In the PLPLOT introduction it mentions the ability to make bar, and pie
  graphs. I can see how to do a bar graph fairly easily, but I'm stumped
  on how to get pie graphs setup. Any suggestions?

Thanks for any answers you might be able to give me. And thanks for a nice 
library that will finally let my Amiga do some serious plotting for me.
