Pie chart SDS

Generates a pie chart for a data set, with the option to add drill-down trees for additional data sets. You must populate the data set by using a service.

Restriction

The Pie chart must be populated by using a service.

Note: If you encounter sizing problems when you display the chart in a collapsible panel, use the following code on the On expand event of the collapsible panel to adjust the chart size to the available space: ${CHART_CONTROL_ID}.refresh();

Configuration properties

Under Configuration, set or modify the appearance and behavior properties for the view.

Screen size: A configuration property that has the Screen Sizes icon beside the property name can have different values for each screen size. If you do not set a value, the screen size inherits the value of the next larger screen size as its default value.

Theme definitions: Theme definitions specify the colors and styles for a view and determine its appearance. You can preview the look and feel of views in the theme editor. See Themes.

The appearance configuration properties for the Pie chart SDS view are shown in the following table:
