The calculated field feature allows users to create custom fields which are not present in the actual data. Users can create these fields using basic mathematical expression collaborating with existing fields. Calculated fields can be created through UI dialog as well as code behind and it can be enabled by setting allowCalculatedField as true. The calculatedFieldSettings property is available to configure the calculated field in code behind. The pivotgrid widget features are segregated into individual modules. To add calculated field, we need to inject CalculatedFieldService module into the @NgModule.providers section.
