Re: [Gnuplot-info] how to plot a line in the contour map

[thorneliu <liu...@co...>]

Oh,yes 
This is really what i want.
I tested the codes you posted and I got the right figure in another PC with
gnuplot 4.2.6 installed.
I think the failure in my Debian GNU/Linux system results form that I am
using an old version gnuplot.
Thanks a lot.
Problem Solved.
