[Octave-bug-tracker] [bug #48474] [mxe-octave] enable better supported gnuplot terminals

[Dan Sebald]

Follow-up Comment #82, bug #48474 (project octave):

>> Two of the GUI buttons do not do anything,

I just ran gnuplot to test those buttons in the Qt terminal.  Placing the
mouse over the button brings up the tool tip which says "Previous zoom" and
"Next zoom".  That would suggest these buttons are a way of navigating some
kind of zoom history.  The "+" and "-" would suggest zoom-in and zoom-out but
that isn't what they do.  Since you probably have not done zoom, selecting
those buttons is already at the front (and end) of the list of zooms.  To
zoom, use the right mouse button to click on the plot window and release to
select a box which will be the new zoom.  After that, the "+" and "-" buttons
should do something.  I find it slightly confusing and will take up the issue
with gnuplot discussion list.  BTW, the "1" means go back to the "unzoomed"
plot, i.e., the first plot (again, a misleading plot)... oh, and maybe you
have discovered some odd behavior with the "+"/"-" in the sense that the zoom
history is kept around even though a new plot is done, which may be in a
completely different range than the first plot, hence it zooms to a region
were there is nothing but empty space.  I'll raise that issue with the
discussion list as well.

Regarding these slow plots (presumably with not too much data), I would guess
the pipe connection is being lost.

Could someone describe what gnuplot_qt is in Windows?  Is it a special
compilation with code from somewhere other than the main gnuplot development
site?  Regular "gnuplot" can have a Qt terminal; it's just a matter of having
the proper Qt packages installed so that "./configure" can find them.
