Usage conisderations

Using a!pieChartConfig()

• a!pieChartConfig() is always used within a pie chart component.
• This configuration is used when a record type is defined as the data source for a pie chart in the data parameter of a!pieChartField().
• If no measure is provided, the chart displays a count of records. Also, the label displays as Count of <primary key field name>.

Using groups and data limits

• The primaryGrouping is required to display data on the chart.
• The dataLimit determines the total number of slices displayed in the chart.

Using dynamic links and aliases

• When a dynamic link is added to the link parameter, the current selected data is available using fv!selection. This variable returns a map that contains each of the field aliases as the key and the unformatted value as the value. Since the alias is used for the key, aliases are required for each grouping and measure when using a link. See Chart Configuration Using Records for an example of how to configure a link.
