[Gnuplot-info] Problem with gnuplot

[DELIMA C. <de...@en...>]

Hello,
    I'm actually student at the university of Nantes and I'm having 
problems with gnuplot.

    I'm working on a project in which I have to draw a representation in 
three dimensions of a matrix. The only problem I have is that I can't 
find how to make a good display in which I can see clearly each "peak" 
and especially to distinguish where do I find higher frequencies.
    To make you see what I have for the moment I'm sending you my file 
.gnu with the different functions I applied. I can't send you the file I 
use with the different frequencies (the file weighs 700 KB) but I wish 
that you could help me. The file "Plots.dat" contains the different 
frequencies I have calculated in a program. The frequencies are sorted 
by x and y as a matrix :
    1  4  6
    8  5  5
    7  3  6
    4  2  9
    (for example).

    I thank you in advance,
    Delima Christophe
