report with accumulation

[#1]

I have table of users as:

Login	date_register (mm-dd-yyyy)
user1	01-01-2013
user2	01-02-2013
user3	01-01-2013
user4	01-02-2013
user5	01-03-2013
...	...

I need to make report as:

date (mm-dd-yyyy)	Count of users
01-01-2013	2
01-02-2013	4
01-03-2013	5
...	...

If i select '01-02-2013' and '01-03-2013', i want to see this report as:

date (mm-dd-yyyy)	Count of users
01-02-2013	4
01-03-2013	5

How i may make it? (If i check accumulation checkbox in expression i have counts of user for 01-02-2013 = 2 and for 01-03-2013=3 )

You can use rangesum(above(count(FIELD),0,rowno())) to emulate the full aggregation, and then add advanced aggregation to limit the values to your selection (this requires that your date field's load order is sorted chronologically, as in your sample data).
