Hi,

Input data

I extract a list of issues from JIRA UI (extract all fields), that is the datasource. This is the structure:

Datestamp (e.g "06/08/2019 03:07:00") | label1 (e.g: "Request type 1") | label2 (e.g: "Request type 1") | label3 (e.g: "Request type 2")

Note label columns are used by JIRA to store multiple labels for one ticket, so if i look for one specific label, it can be in one of the 3 columns, or none.

My goal

I want to make a graph with the week numbers in X (e.g "2019-W31") , the number of occurrence of labels in Y, and one serie for each label (cumulative per week)

Exemple:

This data

Will give the following graph 

Can you please guide me how to do that?
