This is a piece of code that uses Python and CERN's PyROOT library to plot data on a graph. It was written during my IT stage at CERN. The produced graphs are like these:

plot1.py	plot2.py

• plot1.py plots the number of requests received each day
• plot2.py plots the type of requests received by timestamp
• plot3.py plots the type of requests received by experiment

1. Install Python 2.7 on your machine
2. Install ROOT library from CERN's official website
3. Clone this repo and cd into the src folder

   git clone https://github.com/P2-718na/CERN-plots.git
   cd CERN-plots/src
   

4. Get some data. I couldn't upload the whole dataset i used to make the graphs (400MB), but you can use sample.json and sample-parsed.json in the samples folder to get an idea.
5. Open a Python console and run the program

   python
   execfile("plot[1|2|3].py")
   

6. If you want to make changes to the graph, re-run execfile("plot[1|2|3].py")
   without closing the Python console (it will be faster, since you won't have to re-read the whole dataset)

• If you are a CERN employee, you can download the plot1.ipynb notebook, upload it to CERNbox and run it using SWAN
• If you are not a CERN employee, you can still view the notebook using Jupyter notebook viewer
