[Octave-bug-tracker] [bug #43907] OpenGL render code called even when gnuplot is graphics_toolkit

[Dan Sebald]

Follow-up Comment #19, bug #43907 (project octave):

Oh, WXT.  I should have thought of that.  I suppose that terminal understands
FreeType fonts where x11 and Qt don't.  Is it adequate to just suppress the
warning message if the Figure's toolkit is gnuplot?  Apparently the gnuplot
toolkit is placing the desired text in the command.

With the warning message gone, we could rewrite gnuplot toolkit so that it
uses a font that has the symbol characters whenever /Symbol is placed in the
text.  That way the symbols always come out correct.

There is also the ability to place simple programming instructions in
gnuplot:


 New syntax:
       if (<condition>) { <commands>;
              <commands>
              <commands>
       } else {
              <commands>
       }
 Old syntax:
       if (<condition>) <command-line> [; else if (<condition>) ...; else
...]


which would allow instructing gnuplot to check whether the terminal is WXT. 
If so, use the font, if not use a symbol font.
