Grafana State Timeline losing details while using single color

Grafana Dashboards
1

Grafana version: 8.5.9

I’m trying to represent a Gauge through a State Timeline. The value of the gauge represents the state. A label “name” is set depending on the product that I monitor.

I do the following query:

dbk8s_status{name=~"eck-operator|eck-operator-crds|eck-stack|grafana|grafana-dashboards|jenkins4db|mariadb|mongodb|mongodb-backup|mongodb-job|prometheus|redis"}

Then I created as many “value mappings” as I want to represent state and I set Standard options > Color scheme > Single Color To solve the problem describ in this topic.

Here is the result:

result
result1823×789 31.7 KB

Here is what I expected:

expected
expected1847×790 27.8 KB

I got this results by deactivating Standard options > Color scheme > From Thresholds. As you can see details have appareared (Null value aren’t connected) despite Connect null values still set to never.

How can I have still have value mapings and details ?

Thank for your help !
