Read the docs 8^). I originally called this procedure Set_Pen_Color (..) but changed it when I figured that not everyone appreciates the reference to pen plotters and would respond, "What pen?" Calling this proc simply causes everything that is drawn thereafter to be in the specified color, until the proc is called again with a different argument. > Can I put an item on the Plplot binding wish list? > That would be: show some examples that use the thick > bindings, on the web pages. =A0Maybe these examples using > thick bindings will then help some demonstrate why they are > using a language that offers more than Fortran 77 style C. I couldn't agree with you more. In fact, I developed the "Ada-name" binding first and made the "traditional-name" later at the request of the PLplot developer team. I'm very happy to report that I took your petition to the developers and you should soon see Ada examples written with both bindings appearing on the PLplot web site with the "Ada-name" versions given preference if possible. I'll post back here when that upgrade happens. > I'm still looking for an alternative for some Perl-driven > GNUplot command scripts, so I'm really happy to see PLplot > growing into the post-70s era ;-) We try hard. 8^)
