One thing we should review from the animation is the New Data Graphic dialog box, shown here. You'll see that there are two Data Field items listed: one for Average time (days) and one for Orders in Process. These two items correspond to the data callouts in the data graphic. Average time (days) corresponds to the text callout showing the Average time in days. And Orders in Process corresponds to the data bar callout. So the number of items in this dialog box directly determines the number of data callouts in that data graphic.
