[Octave-bug-tracker] [bug #48208] "markersize" compatibility

[Rik]

Follow-up Comment #7, bug #48208 (project octave):

@Dmitri: Good digging through the documentation to find that specification.  I
think Octave must have it wrong then.  For a circle the calculation is sz/2
and for a dot we use sz/3.  The older Matlab docs suggest we should really be
using


(sz/2) / 3


for the dot size.  I think we also need to specify a minimum for the computed
size of at least one pixel.  At the moment, 


h = plot (0.5, 0.5, '.', 'markersize', 1)


produces a blank plot.  I need to use


set (h, 'markersize', 2)


before I can see anything.  I would still be interested in the table of
markersizes to see if they are using a different sizing algorithm for the
smaller markersizes versus the large ones.
