I was wondering if it could be possible without too much effort to
enable mouse-wheel-based scrolling or zooming as described here:
http://gnuplot.info/docs_6.1/loc14336.html
I know that in a gretl-controlled plot one can already select
"zoom..." and then define a rectangle with the mouse. This works nicely.
OK, so in the meantime it turned out that this rectangle-zooming isn't
something that came with gnuplot for free in this context. And so having
the mouse-wheeling wouldn't be so easy to achieve in a native gretl
window (with a plot inside).
I also know that after saving the plot as a session icon and then
executing the raw gnuplot code, one gets a native gnuplot window (not
gretl-controlled), and there the mouse-wheel thing works as well.
(This is on Windows 10.) So as an alternative route it might also be a
possibility to make it easier to send the plot directly to native
gnuplot, instead of having to go via the raw plotting code first.
This seems like the way to go...
cheers
