Specifies the field name whose value is used for the SweepAngle property of the data-aware chart values. Use DataFieldSweepAngle to bind each data-aware chart value to a field object in the dataset. To fully specify a database field, both the dataset and the field within the dataset must be defined. The DataSource property of the chart specifies the dataset that contains the data field. The field object needs to be convertable to a floating-point value.
Use the other DataFieldXXX properties to specify the field names for other properties of the chart value (e.g.,
DataFieldCaption specifies the field for the Caption property of the value). For chart value properties that don't have a corresponding DataFieldXXX property, you can use the
OnGetChartValue event to change their values.
