Sum Up Top N

[qolkaram]

HI every one ,

I have below sample data:

REPORT_DATE	month	Site_ID	outage
6/1/2016	2016-06	1	120
6/2/2016	2016-06	1	500
6/1/2016	2016-06	2	300
7/1/2016	2016-07	4	120
7/2/2016	2016-07	3	500
7/2/2016	2016-07	3	300

I want to sum up Top N Site Outage per month (first i should calculate site outage per month then sum up top N site outage per month) .  I have to do it in front end (in expression) not in script.

I appreciate if someone help me.

here is my requirement:

1- calculate total monthly outage  for each site_id 

2- select top 25 side_id with highest outage for each month .

3- sum up the 25 outage for each month and plot it in a bar chart

Do you want to see single bar for each month?
