Re: how to increase line width?

[John B. Thoo]

Hi, Claudio.  Thanks for your suggestions.  However, I find that

octave:1> toggle_grace_use
error: `toggle_grace_use' undefined near line 1 column 1

I also find that

octave:1> x = linspace (0, 10, 101) ' ;
octave:2> plot (sin (x))
octave:3> hold on
octave:4> plot (cos (x))
octave:5> __gnuplot_raw__ ('replot ''''notitle with lines lw 4\n')
error: `__gnuplot_raw__' undefined near line 5 column 1

I think that I have to upgrade Octave to a later version as Joe had 
recommended.

Cheers.
---John.
