[Gnuplot-info] 2D spatial grpahs

[Peter P. P. <pet...@ya...>]

Hello

This is my first time using this mailing list. Apologies if I don't  
adhere to the rules

My input data looks like so
[x,y,z][x,y,z][x,y,z][x,y,z][x,y,z]
[x,y,z][x,y,z][x,y,z][x,y,z][x,y,z]
[x,y,z][x,y,z][x,y,z][x,y,z][x,y,z]
[x,y,z][x,y,z][x,y,z][x,y,z][x,y,z]
[x,y,z][x,y,z][x,y,z][x,y,z][x,y,z]
[x,y,z][x,y,z][x,y,z][x,y,z][x,y,z]

Therefore, it is the collection of z values for a rectangular  
environment

and I need to take those values and generate a quasi-3D graph like so http://en.wikipedia.org/wiki/File:Autocorrelationplot_grid_cell.JPG

I say "quasi-3D" because I want the third dimension (z) to be a color,  
instead of a height value. My problem is that I don't even know how to  
do google searches for this. Is it a 2D spatial graph, or a 3D color  
intensity graph...

Cheers


Peter
