History_Graph shows only positive values

Hi,

Within the configuration file I defined a history graph with 4 different values.
history_graph:

  solar_graph:
    name: Solar Graph
    entities:
      - sensor.blnet_analog_1
      - sensor.blnet_analog_3
      - sensor.blnet_analog_6
      - sensor.blnet_analog_2
    hours_to_show: 48
    refresh: 300
    - sensor.blnet_analog_2

Then I added this history graphs to groups.yaml

solar_graph:
  name: Solar Graphen
  view: no
  entities:
    - history_graph.solar_graph

And I assigend this sub-group to a main group.

My issue is, that one of this value can turn to a negative value, but in the graph it ends at 0. How can I extend this graph to show also negative values?

Br,
Johannes

This should the history graph do by itself if there are negative values in the database.
Do you see the negative values when you show the more-info dialog for the sensor?

Yes, I am also showing the sensor as a value, and there I can see the negative values

Why do you have the ‘sensor.blnet_analog_2’ twice, under the refresh option?

Please ignore it.
