Making a Pie Chart for a boolean field with true/false labels

Grafana Pie Chart Panel
1

  • What Grafana version and what operating system are you using?
    Grafana v11.1.4 (2355de00c6) on Linux

  • What are you trying to achieve?
    I want a pie chart to represent a boolean custom field myPrefix.isMySuffix from an elasticsearch data source. I want the segments to be labelled true/false (or yes/no or 1/0).

  • How are you trying to achieve it?

  1. In the query, I am using the Metrics tab and have selected Metric: Count and Group By: Terms: myPrefix.isMySuffix.
  2. In [the options pane > Value options], I specified Show: All values and Fields: Count.

  • What happened?
    I get a pie chart where both segments are labelled ‘Count’.

  • What did you expect to happen?
    I expected that the labels would correspond to the values true/false (which are the values in my data for the field myPrefix.isMySuffix.

  • Can you copy/paste the configuration(s) that you are having problems with?
