how can i change height of my histogram?
depending on what you want:
- you increase the window size (use your mouse, or create the canvas with a given size)
- you add more entries (TH1::Fill)
- you scale the histogram (TH1::Scale)
- you set the maximum (TH1::SetMaximum)
Seeing your many (basic) questions on histograms you should probably have a look at the users guide root.cern.ch/root/html/TH1.html
