grAxis objects in Graph controls
DataType is a property of the grAxis objects that can be part of graph controls. There are three grAxis objects: Category, Series, and Values.
DataType specifies the type of data that is assigned to the axis. Possible datatypes are Number, Date, DateTime, Default, Double, Text, and Time.
To specify datatype:
Display the Axis tab page of the graph control’s Properties view.
Select the desired Axis type from the Axis drop-down list.
Select the desired datatype from the DataType drop-down list.
The DataType property takes a value of type grAxisDataType.
The following line sets the DataType of the Values axis of a graph.
