Detailed Description

Dynamic list entry which links a histogram to a certain tree.

Method Process performs a single event TTree::Draw on this tree and directs the output to the histogram. String Parameters Varexp and Selection of Draw() are stored in the entry and are used for each Draw. This dynamic list entry does _not_ use the Go4 Conditions and event index scheme!
