I have the same problem under both Octave 3.6.2 and a fresh 3.7.1+ build 
of the default branch (both in Ubuntu 12.10 / i686-pc-linux-gnu).

The problem exists both with gnuplot and FLTK as graphical toolkits.

I have also tried to modify the 'FontSize' property for hc(2). The 
result is slightly different : it works with FLTK but does nothing with 
gnuplot.
