Hi Matt,
as far as I understand what you ask for is in Rene's pipeline (see
roottalk: RootTalk: Re: Text Axis Labels of 02 Oct, 1998 and
also the still empty SetLabel(Text_t* label) etc. in TAxis)
Unfortunately you want to change the label to decreasing values,
otherwise you could simply use
Set(Int_t nbins, Axis_t xmin, Axis_t xmax)
but this needs xmin < xmax
Cheers,
Otto
