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.

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 >
