I have some reasonable sized 3D arrays that I am working with (~3500 x 488 x 1) which basically is a height map.

gnuplot> set xlabel 'X'
gnuplot> set ylabel 'Y'
gnuplot> set zlabel 'Z'
gnuplot> set palette
gnuplot> splot 'c:\temp\ShowDoubleArray_OD5_RAP10.RawData.txt' with lines palette

0 0 0.0343
0 1 0.0345
.
.
0 487 0.035

1 0 0.0343
1 1 0.044 etc.

The performance is quite bad when I try to rotate it. The current file I am working on is 28megs, but since I am running on an I7 with Flashdisk then it should not take long to load. At least I have an analytical application also working with this file, and file IO is fast.

Any performance tips that someone can propose (and downscaling is not the answer, I am looking for some minute details that are apparent in GnuPlot)

Yours sincerely and with appreciation.
Jes R.
