thanks.I have matrix file, and I need to plot it by GNUplot, who knows how to
do it ? thanks lot.
do it ? thanks lot.

If you already have grid data, just splot them.
If not, you need to set dgrid3d first.
If your file is in matrix format already.
splot "data-file" matrix
command you may need to check in gnuplot mannual.
1. splot (pay attention to the interpretation of data-file)
2. set dgrid3d
3. set surface
4. set pm3d
5. set contour

thanks so much,tlenet.
I want to plot a 2D graph,in my matrix file, all elements are 0 or 1, so I
need to plot all 1s,and discard all 0s, how do I do? like sequence match,if
two sequence are match, then plot a dot , if not match, then ignore.
thanks .

then just plot the pairs with value 1, dicarding those with 0.
Don't use matrix, just use a regular data file with three columns.
set view 0,0
splot "file" using 1:2:3
