To get full control over gnuplot "term" (and output filename): 1 display the plot 2 save as icon 3 edit plot commands 4 save the plot commands to a file 5 edit the file as you wish (I guess 4 and 5 could be reversed) Then run gnuplot on the saved file to generate whatever kind of plot you like. When a plot is displayed by gretl itself, we need to have control over the sizing so we're sure to be able to add our menus, size the window correctly, and offer rescaling of the plot that will work (the "bigger" and "smaller" buttons).
