[Gnuplot-info] pm3d: question

[Arunas M. <mat...@gm...>]

Hello.

I have 3D data file. I want to visualize it in pm3d style and I need
that a certain function would be applied to the 3rd column.

For example,

File data.dat
0 0 2
0 1 3
1 0 5
1 1 6

should be vizualized as

0 0 log10(2)
0 1 log10(3)
1 0 log10(5)
1 1 log10(6)

What should I do?

Best regards
