Histogram references can be created with calls to BOOK_HISTOGRAM or GET_HISTOGRAM. Histogram references are also created by arithmetic between existing histograms.
If this argument is an expression which results in an histogram, the member name should be specified.
This argument should be of type String.
If the member name is omitted, a default member name equal to the name of the global variable associated with the histogram, will be assigned to the histogram. This is in many cases a meaningful default and there is therefore rarely a need to specify a member.
This argument should be of type String.
[By default, set to "none".]
