[Octave-bug-tracker] [bug #48626] Patch with FaceColor "flat" does not display correctly if "FaceVertexCData" is a scalar

[Dan Sebald]

Follow-up Comment #5, bug #48626 (project octave):

The third demo is much better.  I can see the difference in the fourth plot
right away.  The annotation text box for your note doesn't have much margin. 
It appears the margin doesn't work:


demo('isosurface', 3)
h = annotation("textbox", [0.5 0.5 5 5], "String", "Hello World!")
set(h, 'margin', 20)


Perhaps I'm misunderstanding 'margin'.

The first two demos I don't understand how lighting works, but I'm not
familiar with it.  The light source is stationary with the plotting axes?  Not
the view, correct?  Just something I need to get used to.
