Hi All
Is there a way to make a patch (as produced by the 'patch' command)
semi-transparent? I tried setting the 'facealpha' property to 0.5 but
that didn't do what I expected.
BTW. I'm running a checkout of the development sources from some time
yesterday.

Using a development version of gnuplot (4.3.cvs) this can be
implemented
fairly easy. See attached patch. I am hesitating in providing a full
changeset, since we would depend on a development version of
gnuplot. I
see no easy way to check for this gnuplot feature otherwise we could
support this conditionally. I think we have to wait for gnuplot
release
which supports this feature.
