Group by option in HANA studio in graphical mode

Hi,

In calculation view i made union of 2 analytical views having information for 2 plants. now i can see the data in calculation view where i can get aggregation for the column NETWR. Now i want aggregation plant wise, like we do group by in SQL, i need Group by (sub totals) plant wise in graphical mode.

Please let me know if we have option avaliable in hana studio for using Group By
