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. -- Dr. Nick van Eijndhoven mailto:nick@phys.uu.nl http://www.phys.uu.nl/~nick -------------------------------------------------------------------------- Org.: Utrecht University/Nikhef, Department of Subatomic Physics Address: Princetonplein 5, NL-3584 CC Utrecht, The Netherlands Phone: +31-30-2532331(direct) +31-30-2531492(secr.)
