Text Axis Labels

My ROOT application uses a number of graphs of time series for which the
logical axis labels are alphanumeric representations of dates and times.
A roottalk digest entry of 16 April, 1998 demonstrates a simple way to
produce such labels more or less manually using raw text objects. The
same message also alludes to the infrastructure in place to generalize
the use of alphanumeric axis labels, which I gather from the source
refers to TAxis::fXlabels, TAxis::SetBinLabel(), etc.

Is this infrastructure currently usable for this purpose? (A recent
download of the posted source suggests not.) I could, of course, attempt
to augment the demonstrated text method to automate tasks such as
placement, scale, text size, etc., but this effectively reimplements
much of the current axis label work without extending the code
significantly. Is there some more general contribution in this area a
ROOT novice might reasonably tackle?

thanks,
