[ROOT] TTree question.

Dear friends,
In performing some data analysis I want to create an output tree
of which a certain branch BRHIST contains a histogram.
The tree contains of course several entries of which each entry has
a certain event number stored as EVT.
In my analysis I would like to display for a certain event (let's say
EVT==101) the corresponding histogram from the branch BRHIST.
How should I achieve this ?
Obviously I would like to use the TTreeViewer facility of the tree
for it, since on basis of how the histo looks like I would also like
to investigate several other variables of that event.

                                                  Cheers,
                                                   Nick.
