How to add a 2nd line on top of the first one to show 5 kW feeding into the grid in GREEN and 3 kW charging in ORANGE on top ?

[typxxi]

I have this graph which shows the power I am feeding over the time

But how can I add a second sensor maybe in orange on top of the current one which would be on top of the current one and showing around 3000W value?

I want to see the power I am feedin into the grid and also the power used to charge the battery.

I really aprreciate the help from anyone of the community to solve that issue for my 85 year old father who started the journey to move ahead and buy a silent EV and then PV system now with even a battery and a heatpump.

Thanks a lot

Here is the code for the feeding and als the battery charging, but not on top of each other as intended.

I have found the feature
stacked: true

But that did not work out for this type: area

Maybe it is an columns only feature.

When I used columns it seemed to crash so I closed the window first.
Too many columns to draw I bet if every measurement becomes a rectangular.
