You are out of hope here, because pcolor is not implemented in
octave-graceplot.  BTW, many other functions are also unimplemented, like
pie, mesh, and quiver (for a full listing, compare teh directories
/var/chroots/sid/usr/share/octave/3.0.1/m/plot/ and 
/usr/share/octave/packages/graceplot-1.0.5/alternatives/).

Perhaps, the upstream author should include dummy functions in the
alternatives/ directory for all those functions in m/plot/ which are lacking
in the package. I will see if I can find a workaround for this problem.
