[Gnuplot-info] about graphic display controlled by mouse

[bsmile <dev...@gm...>]

I got two questions here, 

(1) how to undo the enlarged region back to the original region? 
one can press the right button of the mouse and move to select a region in
the graphic display to enlarge the graph and release the button to view the
details, but how to restore to the original scale after I finished viewing
the details? I have to type in command set auto x and set auto y to restore
it, but I guess there is simple mouse operation to do that ...

(2) how to restore the x/y scale orientation?
After I crazily clicked on the graphic screen, it mysteriously switched the
y axis to increase from up corner to low corner(the default is from low to
up), how to switch it back to the default?

Thanks,
