I can't get the code sample to work. When I try just the fill command by itself I get

This occurs with either backend.

The EdgeAlpha and/or EdgeLighting properties do not seem to have an effect on Fill() or patch() plot objects. Example code:

f1=figure(1)
clf;
hold on
grid on
h=fill([90,210,210,90],[-.8,-.8,.8,.8]);
set(h,'FaceColor',[0,0,0]);
set(h,'FaceAlpha',0.25);
set(h,'EdgeColor','none');
set(h,'EdgeAlpha',0);
set(h,'EdgeLighting','none');
axis([50,250]);

What I expect is a totally flat, featureless transparent rectangle.

What I get is a transparant rectangle but nothing I try gets rid of the edge of the rectangle. I have tried various values for EdgeAlpha without success. Same for EdgeLighting.
