Hi Peter,
yes, look at the TAxis class.
If you have, eg, a 2-D histogram TH2F *h2,
you can get a pointer to the x axis object via TAxis *xaxis = h2->GetXaxis();
and the y axis via TAxis *yaxis = h2->GetYaxis();
then, do
 xaxis->GetBinCenter(bin) same as hix
 xaxis->GetBinLowEdge(bin)
 xaxis->FindBin(double x) same as hxi

and many more functions.
