Clicking on the plot window will make it "active" for the window
manager (KDE, gnome, whatever), but has no  effect on gnuplot.
Gnuplot has only one active plot, the one produced by the most
recent plot or splot command.

Probably, but it will be a window manager command rather than a
gnuplot command.

What do you mean "activate"?  If you mean "I can use zoom and replot"
then this is not possible at all. It is a fundamental limitation of
gnuplot that only the information for the most recent plot is available.

This, however, should work in both Version 4.0 and the cvs version.
Are you saying that mousing does not work at all in the "old" 
plot windows, or just that the output format changes somehow?

Mousing is supposed to work.  Zoom, replot, or other commands that
require access to the original data can only work on the current
(e.g. most recently drawn) plot window.

The SAVE command might be useful.  In the past I used "save 
x11-fig-NN.cmd", then moved on to
my other plots.  When I wanted window NN I could use a "load 
x11-fig-NN.cmd" to get the window back.
I would wrap this procedure in a OPEN-FIGURE command that would do all 
the book-keeping for me.  See
below example.

Hope this helps.

That would be nice to bind (see help bind) a hotkey to "load" such a
configuration file for a given x11 window. However, binding to the "load"
command does not work as both load and string_execute do some
"extraordinary" things with the current command string and its parsing.

That was just a note if someone finds how to fix it (I haven't found a way
to solve this).
