Examples

The following examples aim to only describe the configuration of the dashboard widget field objects for the Pie chart widget. For more information on configuring a dashboard, see dashboard.create.

Configuring a Pie chart widget

Configure a Pie chart widget in the following way:

  • 2 data sets for a total of 9 items on 1 host.
  • The first data set is of type "Item list" and consists of 3 items that are all with type "Normal" and represented by a different color.
  • The second data set is of type "Item pattern", consists of 6 items, has a configured aggregation for each item, and is represented by a custom color.
  • The second data set also has a custom data set label.
  • Data in the pie chart are displayed as a doughnut chart with a custom width and total value with units in the center.
  • Data in the pie chart are displayed and aggregated for a custom time period of the last 3 hours.
  • Pie chart legend displays configured items in 4 rows.
