The data

As in other types of reports, the PRINT statement in the BDL file specifies the data structure of the information that is available for the graph:
ON EVERY ROW
 LET lineitemprice = orderline.lineitem.unitprice *
 orderline.lineitem.quantity
 LET overalltotal = overalltotal + lineitemprice
 LET ordertotal = ordertotal + lineitemprice
 PRINTX orderline.*, lineitemprice, overalltotal, ordertotal

See Creating the BDL File for additional information.

You extract the data structure as an rdd file that you reference in the Data View page of the Report Designer:

A single rdd file can be used to design multiple reports containing the values of various data items from the file. The same data items can also be displayed as different types of charts.
