Pie charts

Use a pie chart to show how different field values combine over an entire data set. Each slice of a pie chart represents the relative importance or volume of a particular category.

A pie chart

Data formatting

Pie charts represent a single data series.

Use a transforming command in a search to generate the single series.

For example, count events in each sourcetype field category.

...| stats count by sourcetype

Check the Statistics table in Search & Reporting after running the search to make sure that a single series is generated. The table should have two columns.

The example search generates the following table.

A search that returns two columns in the Statistics table

The first table column contains labels for each pie slice. The second column contains the numerical values that correspond to each label. The numerical values determine the relative size of each slice.

If the search generates a table with more than two columns, the extra columns are ignored.

Generate a pie chart

  1. Select the Add chart button ( The Add Chart button in the editing toolbar. ) in the editing toolbar and browse through the available charts. Choose the pie chart.
  2. Select the chart on your dashboard to highlight it with the blue editing outline.
  3. Set up a new data source by selecting + Create search and adding a search to the SPL query window. Or, you can select an existing data source under the Search, Saved search, or Chain search sections.
  4. (Optional) You can also write a new ID that describes the search better than the default by changing the ID in Data source name.
  5. Select Apply and close.

Configuration Panel options

You can use the Configuration panel to configure the following pie chart components.

Title

Give your visualization a name. This is also helpful when searching for individual visualizations in the dashboard definitions. This name is not the same as the automatically assigned unique ID.

Description

Give your visualization a description to explain what the user is viewing.

Data Sources

Choose an existing ad hoc search or create a new one.

Position & Size
You can use your mouse to change the size of the panel, or the Position & Size section of the Configuration panel for pixel perfect sizing.

Appearance
Use this option to toggle between either the classic pie visualization, or a pie with a hole in the center.

Labels

  • Toggle the Show Percent switch to show the percentage each slice of the pie takes up from the whole.
  • Toggle the Show Labels switch to show the value of each slice.

Collapse Threshold

Specify the size threshold, as a percentage of the whole pie, at which point slices collapse into one consolidated slice. The number value must be between and including 1 and 0.01.

Collapse Slice Label

Name the collapsed slice.

Drilldown
Drilldown in a pie chart lets users click on a pie slice to open a secondary search using the clicked values. You can enable or disable drilldown in the Dashboard editor. See Use drilldown for dashboard interactivity for more details.

Code
Select your visualization or its search to view and edit the source code in real-time. You can also change the Visualization ID to a more readable ID to help identify this visualization in the source code.

Example

This search uses the bytes and sourcetype fields to generate a single series.

index = _internal | chart avg(bytes) over sourcetype

A pie generated by the search

Here, the sourcetype column provides pie slice labels. The avg(bytes) column provides the relative size of each slice, as percentages of the sum of avg(bytes) returned by the search.

Source options for the pie chart

While some of these options can be set using the visual editor, there are additional options that can only be set in the source editor for splunk.pie. These options are added to the options field of the visualization stanza. For example, the following example shows the addition of background color settings using a hexadecimal code:

"viz_25NNIqLF": {
  "type": "splunk.pie",
  "options": {
    "backgroundColor": "#0000FF",
  },
  "dataSources": {
    "primary": "ds_gcEN4c7Q"
  }
}
