Can't put all my entities with the same kind of values in one graph?

So a short introduction into my problem.
I have three separate small solar systems on my house. One to the east for the morning, one south for during the day and one west for the evening sun.

They all are nicely tracked into HA. Thus I have three separate inputs and I have a helper who sums all the incoming power together so I can optimize my self-consumption. Which works rather well. But now when I try to visualize things, I get two graphs. My helper in one, and the three power entities in another. Is it possible to have all together in one graph?

For illustration purposes here is an image of the history output. As you can see it sees two kinds of entities but they have the same units (W)
