Heatmap chart

Heatmap chart example Heatmap depicting Time of day vs. activity purpose

A heatmap chart depicts aggregate data in two dimensions on one chart.

Usage

Heatmap charts can only be included as panels in Dashboards. See Dashboard documentation for general tips on creating dashboard configurations.

  • Use panel type: heatmap in the dashboard configuration.
  • Each heatmap panel is defined inside a row in a dashboard-*.yaml file.
  • Standard title, description, and width fields define the frame.

Sample dashboard.yaml config snippet with a heatmap
