_______________________________________________________
Details:
The alpha setting for the edge has no effect in the gnuplot terminal. For
example:
graphics_toolkit ("gnuplot")
figure
demo ("patch", 4);
pfid = get(gca, 'Children');
set(pfid, 'facealpha', 0.5);
set(pfid, 'edgealpha', 0.2);
See if that can be fixed so that the edge has alpha scaling, and if not try
for something that turns off the edge with
set(pfid, 'edgealpha', 0);
because it would be too difficult to make the border appear nonexistent when
attempt to match alpha blending. One could set the color of the edge the same
as the face, but can't match alpha. Removing the edge seems a mandatory
feature.
