[Octave-bug-tracker] [bug #38825] OpenGL doesn't draw single points when no marker style is set

[Rik]

Update of bug #38825 (project octave):

                Priority:              5 - Normal => 3 - Low                
                  Status:                   Fixed => Confirmed              
             Open/Closed:                  Closed => Open                   
                 Summary: plot(0,0) shows no dot with OpenGL => OpenGL doesn't
draw single points when no marker style is set

Follow-up Comment #7:

This is the same bug in a different disguise.  Octave doesn't draw line
segments where one of the end points is a NaN.  A sequence like [NaN 1 NaN]
effectively has two line segments, each of which has an endpoint of NaN which
removes the segment from plotting.

A workaround is to add a marker style to the plot such as


plot ([NaN 1 NaN], 'o-') 


I'll  re-title the bug and re-open it, but since this has a workaround I'm
going to lower the priority.
