The problem is that some of my pie charts have dozens of slices or very varying width.
The legend would take just too much space and moreover, there is not that many colors
easily distinguishable by eye so a person would have a hard time to find which item in
the legend corresponds to some slice in the chart.

I think this is the only way out. ;-)

BTW: A percentage in black color on a blue slice is hardly readable. Could pie() also
change a font foreground color if the background is too dark in those few slices? Say
to white? ;-))
