How to achieve "events normalized to 1" and set y axis range?

Asked by Mamutjan

Hi.

I am trying to generate a histogram whose y axis is "events normalized to 1".
How can I achieve it?

Also, in some of the graphics I got, y axis (logY) starts from, say 0.1, but I want it to start from 1. How can I set it?

Regards,
Mamutjan

Hi Mamutjan,

It is enough to use the "normqalize2one" option of the "plot" command, as indicated in the manual. For instance:
  plot MET [ normalize2one ]

> Also, in some of the graphics I got, y axis (logY) starts from, say 0.1, but I want it to start from 1. How can I set it?
This can be done by modifying the root files that hae been generated by madanalysis. Please have a look to the HTML directory that has been created, for instance.

Thanks, I did find the following in HTML/selection_0.C:

mystack_stack_1->SetMinimum
mystack_stack_1->SetMaximum

they seemed to be the part I was looking for, but I couldn't find any related tutorial.

How can I use (run) it after modifying?

Hi,

You can run it as any root file:
 root -l <filename>

Cheers,

Benjamin

Thanks.

By the way, there were some errors in the generated root file:
1. first line included path in the declaration (fixed the error)
2. lines saying "mystack->Add(selection_0_X" (changing to "mystack->Add(selection_0_XX" fixed the error)
3. two lines "mystack_stack_X->SetMinimum(" and "mystack_stack_X->SetMaximum(" (changing to "mystack->" worked)

I couldn't locate the generator code, but hope someone could fix these.

Thanks again.

Cheers,
Mamutjan
