None 3D histogram of energy depositied in Absorber using ROOT

I'm doing my thesis and need to do a simple simulation of photon beam hitting a tungsten absorber/solid converter (Box). I accomplished something close to this using example B1 as a basis, where i modified the materials and the geometry to match my needs. For the energy deposition i introduced a sensitive detector and a , both based on the files "" and "" in example B2.

THis gives me an output for every event (generated photon from gun)that tells med where energy is deposited and how much is deposited. The output is:

trackID: 1Edep:  69.525 keV Position:       0 0 -318.202 um
trackID: 2Edep: 435.476 keV Position: 188.892 -0.0852614 -178.776 um
trackID: 2Edep:   73.24 keV Position: 229.255 -7.13996 -143.099 um
trackID: 2Edep: 210.555 keV Position: 230.104 -9.42939 -145.798 um
trackID: 3Edep:  69.525 keV Position: 204.573 -133.231 563.216 um
trackID: 5Edep: 91.5187 keV Position: 204.716 -133.031 564.194 um
>>> Event: 9 5 trajectories stored in this event. 6 hits stored in this event

which is similar to the one which you get form example2.

Now, what i need is a histogram that shows me the distribution of the energy deposited on this absorber (given a large number of incoming photons). I'm a novice user of Geant4,ROOT and have limited c++ knowledge, though i can follow the code reasonably well.
