MadAnalysis 5

Unable to understand "AddHisto"-class in -E mode of MA5

Asked by SUBHASISH BEHERA

Dear Benjamin,
      I have gone through the paper arXiv : 1405.3982.

I am unable to follow the syntex : Manager()->AddHisto("<Name of Histogram: ptl1>",20,50,500,"<apply to this SignalRegion Name>");

My question is :

Q:1. What will be in the X-axis and Y-axis ?

Q:2. Bin and range is defined for X-axis only, What will be the bin or range in Y-axis ?

Q:3. Can we have more arguments in the AddHisto function ?

Thanks,

Subhasish

Dear Subhasish,

> Q:1. What will be in the X-axis and Y-axis ?
The X axis is the observable you choose to plot, the y-axis is the number of events.

> Q:2. Bin and range is defined for X-axis only, What will be the bin or range in Y-axis ?
There is none. You get the histogram under the form of a text file that you must then postprocess.

> Q:3. Can we have more arguments in the AddHisto function ?
No. Only 1D histograms are supported. However, the code is interface with root so that you could use all root functionalities associated with 2D and 3D plots.

Cheers,

Benjamin
