Well, I was under the impression that ASCII bar plots are the main
purpose of that package...

Ah, thanks, I missed that.

Still, I think I will (eventually) write my own.  Gnuplot plots are
anything but good-looking (unless properly configured which I do not how

I'd really prefer an ASCII art one.
