I would like to have some ideas about each customer depending on how many products he sells each month.
We have created a new feature
X based on some other features.
We have noticed that, in most case, when Feature
X decrease the amount of product sells decrease as it is illustrated with the figure bellow
For each customer, I have a similar plot (i.e in the most cases when the feature decrease buying product decrease).
How can I generalize this analysis for getting one global plot?
