Export ymax Data to txt document

[Bertze]

Hey, if i plot a 2d curve from a data file, gnuplot saves a max value for y called gvp_ymax_data or something like this.

How can i export this one value in a txt dokument?

copy GPVAL_Y_MAX into a user defined variable and save it:
my_gpval_y_max = GPVAL_Y_MAX
save var "|grep my_gpval_y_max | awk '{print \$3}' > file.dat"

I have got an idea in the following to see the above example

set print 'file.dat'
print GPVAL_Y_MAX
set out
