Dear all,
i found this quite old message of the 2nd of October, 1998(!):

Damon,
The data structure for TAxis is ready to support alphanumeric labels
but the methods to draw the info must still be implemented.
I had many requests to support strings in TTree::Draw , TH1 or TGraph.
This implies first to complete the TAxis implementation.
I would like to merge at the same time the TAxis and TGaxis classes.
I hope to have time to do this work around Christmas.

Is this implemented in the meantime and if so, how do i get it to work ?
Ciao and thanks in advance
Thomas
