I think I have said here several times that one of the worst programming
decisions I ever made was to do a direct translation of BarPlot to
cgBarPlot. So, yes, we have to live with our past.

If I were doing this, I would simply suppress the tick labels and add
them myself, rotated at, say, a 45 degree angle so they will fit. You
can do this with cgText. You can find code that does exactly this in the
cgBoxPlot program.

Should this feature be added to cgBarPlot. Probably. Am I going to do
it? No, not right now, unless someone is offering money. Then, I'd try
to fit it in. :-)

Cheers,

David
