[Gnuplot-info] Problem with GnuPlot

Hello,
    I'm writing to you to ask you a question.
    I'm actually working on a project in which I have to use GnuPlot to 
generate a 3D image.
    I'm working under GnuPlot 4.0 on Windows XP Pro and the version of 
GnuPlot of Linuw Mandrake 10.0.

> In this project I've generated a matrix (2 dimensions) with frequencies.

> To work with GnuPlot I have created a file like this:

       0 0 13
       0 1 14
       0 2 18
       ...
       500 499 10
       500 500 7

    I use "splot" with the option "matrix" and  "hidden3d".
    This command works but the problem is that it displays an image 
without color and in all the documentation I've found in Web I've only 
found how to draw colored images with numeric functions as "cos","sin", etc.
    I don't manage to display colors with matrix.

I thank you in advance!
