I'm not sure why you are getting the warning. I don't see that.
However, the title command is being interpreted as "<tab>au"
To get \tau, you'll need to either ...
title ('\tau')
... or ...
title ("\\tau")
OK, the error message only occurs for the title command above, so it must be an error relating to the <tab> interpretation.
title("\\Tau") returns \Tau
title('\tau') returns "t"
title('\gamma') returns "g"
Not greek symbols but the traditional letters. A font issue maybe?
OK, Ben, this is odd.
From the same instance of Octave I re-ran my script with \tau in it, and it worked.
For some reason when I do it from the command line, however, it always works like above (including in a few instance).
However, with the gnuplot it does overlap axis labels with adjacent panes at a font size greater than 12 (specifically 14 and 16). is there a simple way to pad it?
thanks,
