- Common information
- Simple plotting using variables from file
- Search branch using sub-string then plot for all of them

These macro needs uproot and matplotlib packages.
On lxplus this is available with CMSSW_11_2_4 onwards.
If you want to plot one variable on one canvas. Then add each variable with its nbins, minX and maxX info in the file variableListToPlot.py. Then run the macro ReadTree.py.
Example use:
python ReadTree.py -i <ROOT_FileWithPath> -t <TreeName> --dir <DirToKeepPlots> -var_file variableListToPlot.py
# Example
python ReadTree.py -i /afs/cern.ch/user/r/rasharma/work/h4L_analysis/UFHZZAnalyzer/CMSSW_10_6_12/src/Sync_1031_2018_GluGluHToZZTo4L_final.root -t Ana/passedEvents --dir h4l_plots -var_file variableListToPlot.py

optional arguments:
-h, --help show this help message and exit
-i INPUT_FILE, --input_file INPUT_FILE
Input root file

text file having list of all variables.
-d DEBUG, --debug DEBUG
debug true or false

Directory name to keep plotsIf you want to plot all branches from the tree having a particular pattern then use the macro ReadTree2.py.
Help message:
$ python ReadTree2.py --help
usage: ReadTree2.py [-h] [-i INPUT_FILE] [-t TREE_NAME] [-nBin NBIN]
[-xmin XMIN] [-xmax XMAX] [-branch_text BRANCH_TEXT]
[-d DEBUG] [-dir DIR_TO_SAVE_PLOTS]
Search all branch having a sub-string. Then make histogram for
all the available branches.
Example Command:
----------------
python ReadTree2.py -i InputRootFile.root -t TreeName -branch_text "D_" --dir temp
----------------
optional arguments:
-h, --help show this help message and exit
-i INPUT_FILE, --input_file INPUT_FILE
Input root file
-t TREE_NAME, --tree_name TREE_NAME
tree name of input root file
-nBin NBIN, --nBin NBIN
number of bins
-xmin XMIN, --xmin XMIN
min value of x-axis
-xmax XMAX, --xmax XMAX
max value of x-axis
-branch_text BRANCH_TEXT, --branch_text BRANCH_TEXT
search string in a tree branch
-d DEBUG, --debug DEBUG
debug true or false
-dir DIR_TO_SAVE_PLOTS, --dir_to_save_plots DIR_TO_SAVE_PLOTS
Directory name to keep plots
