 Hi, You are right: the first histogram is slice VS energy deposited (a more readable plot may have 80. as last parameter, so that you can read mm directly on the x axis). Other histograms instead are energy distributions: the first with a bin size of 1 unit from 0 to 70, and the last of about 7 unit from 0 to 500.

I can't understand clearly some code lines of the HadrontherapyAnalysismanager.cc file of the source file. Especially some code lines as follows: > > 1. h1 = histFact -> createHistogram1D("10","slice, energy", 400, 0., > 400. ); 2. h10 = histFact -> createHistogram1D("100","Energy > distribution of secondary electrons", 70, 0., 70. );// 3. h16 = histFact > -> createHistogram1D("160","Energy distribution of hydrogen fragments > after the phantom", 70, 0., 500.); > > From the Aida web, I think in the line 1,the first 400 means the bin number, the 0.and 400.represent the low and up edge of X axis. Is it right? Then, in default, the slice along x axis is 200 um, the 400. means x axis of the figure represent the depth of 8cm alondg x? > Then how to understand the (70, 0., 70.) of line 2 and (70, 0., 500.) of line 3? Why the last column numbers are different? > > Who can help me? Thank you very much! > > yours sincerely kitty > ```
