From my attached screen shot, i would like to know what are those symbol's are in black circles. I got this screen shot from one of the demo application.
Arrow Symbol is a Drill down group of dimension.
Arrow Circle is a Cyclic group of dimensions.
Drill down group --> Hierarchy structure like Year-->(has 4)Quarter-->(has 3)Month-->(has 4)Week-->(has 7)Day
Cyclic Group --> Its just changing the dimension as our need in single chart.
