Background of Grafana graphics

Hello
Is there a possibility to change the background of the Grafana graphics to dark?

Hervé

Have you checked in the Grafana forum?

I did, but I could not find anything. In the grafana-display that comes with sensor software I do not see a button to change the dashboard setting. Maybe the developers of sensor software have blocked adjusting the settings?
Greetings
Hervé

The whole Grafana:
PM sensors - Dashboards - Dashboards - Grafana (madavi.de)

For colour click on the stripe and then change the colour of the graph.
