How to edit bar chart?

Hello PowerBI-Community

As you can see below, I have created a bar chart by displaying push messages in a certain period of time. The push messages can be assigned to a customer (here customer = ?).

I would like to create a second bar chart, which ONLY considers the respective customer (in this case customer=?)

In this case, the second bar diagramm would show only the filled blue area.

This allows me to better visually see how a customer's push messages differ per day.

How can I do that? I have the attributes date, number of push messages & customer number.

I am incredibly grateful for your help.

Have a nice day

Cheers
