[Gnuplot-info] Re ad string from data file and display on graph?

[whatsherface <het...@gm...>]

I have a script which plots my data exactly how I want it.  My question is,
is it possible to read in a string from a data file and place this text in a
specific location on the graph? (I don't care where it goes as long as it is
displayed horizontally and is outside the axes.)  I am plotting many graphs
repeatedly and would like to display input parameters on each graph rather
than having to refer to each plot's data file to see what it was made from. 
I have been googling for hours and nothing has worked.  I now believe it's
probably not possible but if you have any suggestion that would be much
appreciated.

It sounds like you want either "set label" or to "plot ... with
labels". They are explained in "help label" and "help labels"
respectively. There are demos at
http://gnuplot.sourceforge.net/demo_4.6/datastrings.html and
http://gnuplot.sourceforge.net/demo_4.6/stringvar.html.
