Hello Kyle, In JAS3, select Help -> Examples -> Java Examples -> HistogramArithmetic.java This will show you how to perform the actions you need. To scale a histogram simply invoke the scale() method, documented at: http://aida.freehep.org/doc/v3.3.0/api/hep/aida/IHistogram.html#scale(double) Enjoy the weekend, Norman From: Kyle McCarty [mailto:[log in to unmask]] Sent: Friday, September 20, 2013 1:12 PM To: Graf, Norman A. Subject: JAS3 AIDA Editor? Hello, I have been working with some plots lately and was wondering if there is an easy way to manipulate them with JAS3. Specifically, are there ways to apply normalizations such as a constant scaling factor to graphs or to combine several graphs together? I noticed that under the plot properties in JAS3, there is a "Normalization Settings" button, but it does not seem to selectable no matter what I do.
