Re: Request for Direction in Creating a Gnuplot

I don't know about the file format. Check out "dgrid3d" for gridding nongrid data. However if the data is already on a grid then it would be better to put the data in the correct format (write a quick code to read in your data and output the correct format?). 

Once you have your data you'll want to "splot" it - the commands might look something like

set view map
set pm3d
splot 'data.dat'

the "view map" makes it flat, and the "pm3d" makes it solid colors. The color scheme can be changed using the set palette commands. Try googling these commands and see what you can come up with. The data size is really big! Presumably you can plot whatever your computer can handle (I'm not aware of any software limitations, but may be wrong). On a side note, Octave has the same syntax as Matlab (if that is what you are familiar with) and uses Gnuplot for its graphics, but I think you'll find learning Gnuplot very useful!
