Hi Ryan,
In a mail several weeks ago, I mentionned our intention to implement
support for alphanumeric labels on the axis.
This includes the following functions:
- a simple TAxis function to store a set of labels (pretty simple)
- Interface from the TH1 and TTree classes to:
- TH1::Fill(const char *name, Double_t w)
- TTree::Draw("leaf_of_char_type")
This is quite complex (if implemented efficiently).
This is on my shopping list for the next iteration (probably 2.21).
- Time/Date on axis (no short term plans for this one).
I understand that Damir may come with something in this area.
I also promised a solution to a problem reported a long time ago
by Peter Wienemann affecting Postscript files in case one use
the special fill styles 3010->3030.
