Re: how to increase line width?

[John B. Thoo]

Hello.  To piggy back on this thread, I would like to plot

x=-4:0.1:4;
hold on
plot (x, x.^2, "-r")
plot (x, 0.75 * ((2 .* x).^2).^(1 / 3) + 0.5, "-k")

with a heavier line width for the second graph only.  How do I do this? 
 It wasn't clear to me from the description below.

I'm using Octave 2.1.46 in X11 on Mac OS X 10.3.9.  (I'm sure this is 
an older version of Octave.  I plan to upgrade it when I upgrade the OS 
to Tiger during spring break in a few months.)

TIA.

Best regards,
---John.
