Help to display 90 days record

[#1]

Hi,

I am trying put a chart to display no name create in the last 90 days by title.

here is my ruff data:

Title	Name	Create Date
A	AB	15/03/2012
A	VA	02/02/2011
A	EA	01/02/2012
A	DF	07/03/2012
B	ER	15/03/2012
B	BF	02/02/2011
B	QW	01/02/2012
B	WE	07/03/2012
C	ET	15/03/2012
C	TY	02/02/2011
C	YU	01/02/2012
D	IU	15/10/2011
E	AZ	29/11/2011
I	AX	27/02/2012
I	AC	19/08/2011
J	AF	15/02/2012
K	GH	02/02/2012

the result may come below

Title  Count

D        1

E        1

I          1

Can some one please advise what expression should work to display no name in last 90 days by title?

Thanks,

Dinesh

Maybe something like

sum(aggr(if(max(Create Date)<today()-90,1),Title))

Might need some tweaking to get the desired result but that should help point you in the right direction.
