Hi all,

maybe this has been discussed earlier, but I coulnd not find a thread 
about this.

I want to redirect a plot into a table but such that all data are 
plotted as separate columns. I.e. consider, let's say, a number of 
functions f1 to fn, and the table should look like this

col1  col2   col3  ... coln+1
x     f1(x)  f2(x) ... fn(x)

(replace in mind these labels with the corresponding values)

Currently, gnuplot writes them in blocks one after the other. I know 
that one can plot up to three columns using parametric mode and splot to 
table (this has been discussed here already, AFAIR), but unfortunately, 
I need four columns...

Is it possible to use a print statement inside a for-loop? This would 
solve the problem. I could, of course, do this in an external program, 
but it would be nice and elegant to do this in the same gp script 
without invoking external self-written software.

Thanks in advance!

Ingo
