DAT Chart step allows you to see the result of your DAT Query as a chart. The DAT Chart step is only enabled for queries which have aggregated display fields (DAT Fields - Step 2 - Aggregating). 

The Data Group may be any non-aggregate field and will sub-group the data according to the selected field.

Note: Pivot Aggregate fields do not qualify as an Aggregate field for the purposes of making a Chart.
