Thanks, that helped. However ... problem is, that i use it inside of an
automated process:

1. export data from DB (something like: plot, x, y, value)
2. split data into files according to "plot" and make "isolines" (file format:
x, y, value)
3. create plot files from a template:

set palette
set pm3d map
set terminal png
splot "@@FILENAME@@"

4. execute gnuplot for each plot file and generate png images

If I understand it correctly, then my plot file template should look like this:

set palette
set pm3d map
set terminal png
set xrange [@@XMIN@@:@@XMAX@@]
set yrange [@@YMIN@@:@@YMAX@@]
splot "@@FILENAME@@"

And I should replace the @@XMIN@@ ... @@YMAX@@ values according to the input
data. That would mean, that export of data from DB is not sufficient and I
would have to export also following table: (plot, xmin, xmax, ymin, ymax) and
use that values in the template.

Will this give me the result I want?

Now I have to figure out, how to generate gnuplot files using the min-max table
stored in a file. Replacing single filename was not a problem...
