[Octave-bug-tracker] [bug #40289] Document that low-level graphic functions don't call newplot()

[Rik]

Update of bug #40289 (project octave):

                Category:   Plotting with gnuplot => Documentation          
              Item Group:                   Other => Documentation          
                 Summary: assumed hold on before surface plot and no change of
axislocation afterwards => Document that low-level graphic functions don't
call newplot()

Follow-up Comment #3:

This is the intended behavior.  The low-level graphics objects always add
themselves to the current axis (equivalent to hold on).  If you want to
prepare a figure to receive a new plot you should use a high-level plotting
routine, or call newplot() yourself directly, but that is discouraged.

So, instead of using line() (low-level) use plot().  Instead of surface
(low-level) use surf().  Et cetera, et cetera.
