HIST = VL_AIBCUTHIST(MAP, X) computes the histogram of the data X over the specified VL_AIB cut MAP (as returned by VL_AIBCUT()). Each element of HIST counts how many elements of X are projected in the corresponding cut node.
Data are mapped to bins as specified by VL_AIBCUTPUSH(). Data mapped to the null node are dropped.
VL_AIBCUTHIST() accepts the following options:
- Nulls [drop]
What to do of null nodes: drop ('drop'), accumulate to an extra bin at the end of HIST ('append'), or accumulate to the first bin ('first')
