how to change chart's measure based on filter selection?

[#1]

is that possible in Sense?

suppose my data is shown below,

Month	A	B	C
Jan	1	7	13
Feb	2	8	14
Mar	3	9	15
Apr	4	10	16
May	5	11	17
Jun	6	12	18

if selection is empty, then chart shows the sum of A,B and C. Otherwise, chart shows the selected data.

Thank you!
