The histogram doesnt control the 'representation' of the data on the
screen this way.
So 1D histo stores numbers without any 'lin/log' scale awarness.
This is controled by the Pad it is draw into.
If you are going to draw an histo, that certainly means that you already
have a pad ready for it.

Then gPad (pointer to the current pad) is valid and you simply add the
following line somewhere in your script, just before or after the
hist->Draw() would be good.

gPad->SetLogy();
