Hi, 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. 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. Thanks sven
