Graph for performance over years

Good day.
I probably have a slight problem.
But for me it is just difficult because there are certainly different ways to solve it.

Problem:
I have a table like below. It is only an example.
So I have a group (fire). This group has different products (Stock Package). These have a value that is updated once a month. I buy and sell them from time to time. So far its not working with just the table and a few clicks.

Target:

I want a PowerBi chart that shows me how the performance is. Note, there are about 20 groups, with a total of 400 products.
In the graph you can see the 20 groups.
