In order to work with related fields within a chart, the fields must either be set as a fields element in the PopupTemplate's content or as popupTemplate.fieldInfos property outside of the PopupTemplate's content.

Set the popupTemplate.fieldInfos property for any fields that need to have number formatting for chart/text elements.

normalizeField Property normalizeField String

A string containing the name of a field. The values of all fields in the chart will be normalized (divided) by the value of this field.
