How to make plots

ROOT macro demos are in macors directory. Move to this directory first. Start ROOT CINT and load MACRO. Then execute as samples below.

* IMPORTANT NOTICE *

These are just simple demos. I encourage you to look into the codes and improve it, or make your own. ( If you know ROOT, you can do it =D )

Sample command 1:  mppcTest.C to check one histogram

The function histText() is defined to return TH1D*. You need to create TH1D* and draw histogram.

$ root
root[] > .L mppcTest.C
root[] > TH1D *h1 = histText("h1", "../data/20130305/mppctest001.txt")
root[] > h1->Draw()

Sample command 2:  adcCalibration.C to check three adc data at one time

The function “histText” is defined to return TCanvas*. You need to create TCanvas*. (Canvas will be drawn automatically)

$ root
root[] > .L adcCalibration.C
root[] > TCanvas *c1 = histText(32)

Sample command 3:  tracker.C for eventdisplay

You don’t need to load tracker.C, just type

$ root tracker.C

or, in case you want to start from certain run number,

$ 'root tracker.C(3)'

Change branch descriptor

All macros use method TTree::ReadFile(FILENAME, BRANCH_DESCRIPTOR)() to create TTree from text file. If you changed orders or number of columns of output text format, modify BRANCH_DESCRIPTOR as needed.
