I want to try new things, so I manage this via a milestone instead of a classical issue.

An automatic plotting script is extremely helpful to provide validation plots with fast turnaround times. Additionally, central code minimises manual human errors and enforces a unique and consistent style. Of course, we cannot catch every corner-case, but this should cover 90% of plotting needs.

To-Do List:

• Implement arbitrary number of weight systematics and variable-based systematics for bands in the plots
• Implement parallelisation with htcondor for quick scale out
• Implement CMS label and lumi string in JSON
• Include an option for splitting eta regions: inclusive, EB-EB, EB-EE, EE-EB, EE-EE, not EB-EB
