Hi again,
forgot to mention how each of the plots was created:

Hi Mark,
I have investigated the "point-size" problem and found out the
following:
On my 32-bit machine (where Plot_xcb.cc was mainly
developed) the
problem does not show.
On my 64-bit system (where I hardly use Plot_xcb.cc) the
problem
shows up. As far as I can see, all xcb_fill_xxx()
functions have that
problem. The desired area, be it rectangles, polygons, or
ellipses, is
not filled with the colour set by XCB_GC_FOREGROUND (as they
should IMHO), but is instead filled with the background color.
Also,
the window caption seems to be broken in the 64bit version (it
worked
better with the 32 bit version).
I am afraid that I can't do anything about this (I tried but
failed to
find the source code for the xcb_fill_xxx()
functions on the web).
The gtk-3 version shows none of these problems and is the
currently
recommended version anyhow, so I would try to get that one
working
on your Mac.
If anybody has a clue what all this is about then please let me
know and I'll try to fix it.
Best Regads,
Jürgen
