I know all this...
Maybe I was not clear enough in my answer. What I meant is that your
patch does not change the size of the dot (it uses default values of 1.0,
which is the default marker size used by octave). So the patch has no
visual effect. Setting the marker size to 0.5 makes markers more similar
to dots. So you could define pointsize to 0.5 for dot markers.
