Hi all,

I am not sure if someone else noticed this as well, but the combination of
piechart plots and save.plot does not work correctly. The labels and
tickmarks are plotted OK, but the piechart itself is placed somewhere else
in the figure (when using colors) or not visible at all (if not filled).
The combination with postscript("...") works, though.

Two small thingies concerning pie charts: 
i) If there are no labels, then it is nicer to hide tickmarks as well. 
ii) If the values in vector x are too different, then the polygon drawing
routine protests. Is it possible to draw a real circle? This could be useful
in other plots as well, where the radius of the circle is a measure of the
value in the third dimension.

And yes, I do not like pie charts at all, but sometimes one has to do what
one has to do 8-)

Ron
