AFAIK these are intended to "stack" in the same way that multiple solar productions stack. That way the height of your forecast(s) match with the height of your stack of productions.
Is that what you're trying to say is "wrong" about them, that you don't think that is correct behavior?
I was not aware the lines are also "stacked" as they seem to be 2 separate lines. Of course the sum of both is represented by the top line, but from my perspective it is wrong to treat the lines as a stock unless they are not visually stacked like the production.
The line (in my example with a value of 0.17 Wh) has a value on the y-axis of >1.6. If I would sum up the individual values based on their y-axis value it would be wrong.
In case this is really the intended behavior maybe we can make it obvious that multiple forecasts are stacked/summed up as well?
Looks like this has been discussed a bit before, but both stale'd out without resolution.

Oh right, didn't see them before.
At least @bramkragten made a proposal which would at least display correct values. Downside: it's just one line and hides the details of individual forecasts.
Maybe we can continue the discussion on how it should look like in future, I'm pretty sure more and more people will have multiple forecasts for multiple solar production systems as they get cheaper and more "main-stream" due to Plug & Play...
There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates. Please make sure to update to the latest Home Assistant version and check if that solves the issue.

Describe the issue you are experiencing
After adding a second forecast.solar integration with much lower values than the main one I observed strange graph values in the solar-graph-forecast card. It seems the forecast values are not interpreted correctly in the graph although the legend shows the correct values. As indicated on the screenshot both markers on the line seem to be wrong:![image](https://github.com/home-assistant/frontend/assets/70015952/913277bc-1865-487b-ad4c-6f124052716a)
This does only happen with 2 forecasts, if I disable the main one the new one displays correct values (screenshot from test-system without production data):![image](https://github.com/home-assistant/frontend/assets/70015952/01148abe-d756-4dc4-bb9e-941e61f90030)
Describe the behavior you expected
the dotted lines should be correctly drawn also in case of multiple forecasts
Steps to reproduce the issue
Not sure if this prob1. add a forecast.solar integration with relatively low production values (mine is 860 Wp, Azimuth 219°, 25° angle)
