Using data file for labelling axes

[Nico]

Hi,

Let's consider a data file like this:

Col1  Col2  Col3
0       1      2
1       2      3
...

How can I use in gnuplot script the name of the columns ("Col1", "Col2", "Col3") to label my axes or to define the title ?

Thanks

I generally preprocess the files with gawk or similar.

In your case I'd make something like this

gawk '{if (NR==1) print "set title \"$0\"; else {print "plot \"myfile.dat\" u 1:2 w etcetc "}}' myfile.dat > plot.gpi

so that plot.gpi contains

  set title "Col1 Col2 Col3"
  plot "myfile.dat" u 1:2 w etcetc

then I'd issue

gnuplot plot.gpi

To set the plot titles:

  set key autotitle columnhead

It's not clear how the column head values relate to axis labels.  What value would appear where?

[Nico]

this method (set key autotitle columnhead) gives a partial answer...
How can I do the same for the xlabel (or the title...) ?

Thanks
