Re: [Gnuplot-info] Label value from file and caption under the graph

I don't think that this is possible.
You might be able to somehow do it with variables that you set to contain your text. But I 
don't know how you would set those variables. I don't think you can set variables using a 
datafile (like the plot command). Would be nice though. You could have an external 
program write a file 'setvariables.gp' containing:

set <variable> = <text>

and execute 'setvariables.gp' in your script, like:

load setvariables.gp

Then you could use <variable> in your label command instead of the text.
That might work.
