I just found my old message to Jon Trowbridge about that. I haven't continued
and/or started working on these issues; just have a look at it and maybe it
sounds interesting enough for you to give it a try :-)

Again, this sounds reasonable. Remember to also make the necessary changes
in guppi-pie-print.c:print() so that the printed output will match the

Again, this probably won't be too bad. If you want labels to be able to
sit "on top of" bars (rather than superimposed over them), you might need
to adjust guppi-barchart-view.c:preferred_(x|y)_range to make sure the
labels don't fall off of the pages.

This all sounds reasonable, and these would be great contributions!
