Dynamic Legend by using Variables

Hello,

I try to get the fowllowing stuff to work:

i have a dashboard that shows me 20 Metrics of Power Consumptions. (pic1)
i use 2 variables for filtering the consumptions. (pic2) filter 1 is 0 watts and the second one is 7800 watts.
The filter is “filter data by values” and is config as:
filter type include
conditions match any
match is greater or equal value “$value1” (variable) (pic3)

What i try to realized is, that if I choose the 7800 watts, the Panel and the legend only show up the metrics witch matchs with the transform data.

What is working: If I choose one of the variables, the panel shows only the graphs witch are matching with the transform data. but the legend shows all Metrics.

Some more informations:
I am not an native english speaker, so sorry for communication problems.
i used Grafana V11.1
the graph is time series.
i’m just a user and don’t / can’t admin the grafana server.
As query MetricQ Datasource (Panel-Json).
