Yes, this is possible. Root has more functionality than PAW in this area.
Look at functions:
TProfile *ProfileX(const char *name="_pfx", Int_t firstybin=0,
Int_t lastybin=9999, Option_t *option="");
TProfile *ProfileY(const char *name="_pfy", Int_t firstxbin=0,
Int_t lastxbin=9999, Option_t *option="");
TH1D *ProjectionX(const char *name="_px", Int_t
firstybin=0, Int_t lastybin=9999, Option_t *option="");
TH1D *ProjectionY(const char *name="_py", Int_t
firstxbin=0, Int_t lastxbin=9999, Option_t *option="");
TH1D *ProjectionZ(const char *name="_pz", Int_t
firstxbin=0, Int_t lastxbin=9999, Int_t firstybin=0, Int_t lastybin=9999,
Option_t *option="");
