Pie Charts
A Pie Chart is a Visual divided into slices to illustrate numerical proportions. The arc length of each slice is proportional to the quantity it represents, making Pie Charts particularly useful for expressing a part-to-whole relationship.
For example, the Pie Chart below shows orders separated by salesperson, letting Users easily see which salesperson has the largest portion of overall sales.
Settings
To configure a Pie Chart, open the Report containing the chart, click the ... icon in the top-right corner of the Visual, and select Configure. The left panel has five tabs: Settings, Series, Y-Axis, Legend, and Drilldown.
- Group by: select a Field to use for the slices of the chart.
- Sort groups by: choose how to sort the groups.
- Number of groups to show: the maximum number of individual groups shown in the chart.
- Include other/remaining items: creates a group for all values not included in the number of groups to show. Available for both Group By and Split By.
- Include empty/null items: creates a group for null or empty values.
- Split by field: choose a Field to create a second group to analyze the data (for example, Group by Company, Split by Product).
- Sort Split by Field By: Value, Sub-Group Ascending, or Sub-Group Descending.
- Step, Label Rotation, Zoom, Stacking, and X-Axis title: these settings are not available in a Pie Visual.
Series
The Series tab lets you edit the displayed data or add additional series. Four icons at the bottom of the panel are Series, Color, Label, and Delete.
