Yes, you are correct. I add a line:

graphics_toolkit ("gnuplot")

, and everything works fine. So this is actually a fltk problem.

Thanks a lot.

You mention gnuplot but are you actually using it? At startup, fltk is the default backend (see what  "graphics_toolkit ()" returns) since 3.8 series.

If you can confirm you are using fltk and not gnuplot, this is a duplicate of bug #42320 (and maybe another one I couldn't find.

Recently I upgraded from Ubuntu 13.10 to 14.04, which brings the Octave from 3.6.4 to 3.8.1 and the gnuplot from 4.6.3 to 4.6.4. After the upgrade, the TeX symbols in plots do not work correctly in the output files.

Example code:


The graph shown on the screen displays the Greek character "Pi" correctly, but the output file "testfig.ps" only shows a string "Pi" in Roman characters.

Similar problem also occurs for "-deps" format, and also superscript and subscript do not work.
