Re: subplot titles and labels overlap

[Tatsuro MATSUOKA]

Hello

As far as I know, greek letter like \tau can only be available in TeX mode.
See
http://www.gnu.org/software/octave/doc/interpreter/Multiple-Plot-Windows.html#Multiple-Plot-Windows

Table 15.1: Available special characters in TeX mode

The gnuplot does not have feature to represent TeX letter in the interactive 
terminal
(X11, aqua, windows, wxt and etcs.).  You may only see it in printed files.

Regards

Tatsuro
