x11 terminal activation

[Jacques B. <jac...@no...>]

I wish to use gnuplot to open several x11 terminals, and to change the 
active terminal interactively (with a mouse click for example), in order 
to be able to rescale the plot with the mouse (right clicks).

1) Is there a way to change the active terminal with a command, without 
redefining all the plot? (I didn't find a word about this in the manual)

2) Is there a _simple_ way to patch the source in order to activate the 
clicked terminal? (I tried but didn't get the expected behaviour)

3) I wish that the mouse coordinates in a _non-active_ x11 terminal were 
displayed according to the mouseformat defined for this terminal. Is it 
easy to patch?

4) Is there a completely different way to obtain a similar behaviour 
with the current gnuplot?
