Re: how to increase line width?

[Joe Koski]

John,

To use Grace Plot, it must me installed. There is an easy to install version
of Grace Plot on the Apple web site,
 
   http://www.apple.com/downloads/macosx/math_science/grace.html

It requires X11, and has a learning curve before it is useful. Grace plot
does create good publication quality plots with much more interactive
control than gnuplot.
