[Gnuplot-info] Recognize end-of-file in iterations

[Nunzio L. <nun...@gm...>]

Hi all,

I have some datafiles all named disy.100 in different directories and I want
to plot them all using column 1 vs 3 the latter being divided for the
minimum value in each datafile.

After googleing a bit, for a single file I managed to do:

min=10**10
grab(x)=x<min?min=x:min=min
plot 'disy.100' u 1:($3/grab($3))

and that's fine.

Now I want to do it iteratively starting from the parent directory:

list=system("ls")
min=10**10
grab(x)=x<min?min=x:min=min
plot for[i in list] i.'/disy.100' u 1:($3/grab($3))

but in this case min gets the minimum value of columns 3 of ALL datafiles to
be plotted, while I want it to be the minimum for each dataset.
Do you have any suggestions for doing that other than processing the files
through awk first?

Thanks for your help!

w.
