Dear all

I didn't try the mentioned patch (I do not know how to use it), but I
upgraded to Octave 2.9.16 instead. This seems to solve the above issue.
However, I cannot plot data points with filled circles anymore. I used
to do that as follows:

------------
h = plot(rand(1,5));    % this produces a plot with lines only
set(h,'marker','.','markersize',3) % in 2.9.15 this added solid circles
to the data points
------------

I also tried the following, but this gives me empty circles (I used this
method to produce solid circles in Matlab):

------------
h = plot(rand(1,5));
set(h,'marker','o','markerfacecolor','b')
------------

So: how can I plot solid circles?
