Run off/ Formulas/ Aggr

Hi All

I have a problem and i need some help.

I have a graph which shows me the Full accumulation of payments over a year month on month.

Below is the graph which is aggr and the table which shows payments over the month.

The above is all working.

Now i want to divide each months figures by the Aggr payments as at Dec 2010.

The figure is £90,561,496.

I want to find out the % difference month on month from Dec 2010

So in excel it looks like this and plots on a graph like this.

PY End Incurred	Jan	Feb	Mar	Apr	May	Jun	Jul	Aug	Sep	Oct	Nov	Dec
£90,561,496	£1,107,281	£6,632,026	£8,534,827	£9,130,061	£9,935,255	£9,672,376	£7,921,965	£9,096,020	£7,452,823	£7,268,099	£6,583,660	£4,669,549
1.22%	7.32%	9.42%	10.08%	10.97%	10.68%	8.75%	10.04%	8.23%	8.03%	7.27%	5.16%
=D47/$C$47	=D47/$C$48	=D47/$C$49	=D47/$C$50	=D47/$C$51	=D47/$C$52	=D47/$C$53	=D47/$C$54	=D47/$C$55	=D47/$C$56	=D47/$C$57	=D47/$C$58

Now I got the £90,561,496 by taking it from a list of payments which is the sum of all the payment amounts in the sheet

ID	Payment Amount
803148-G	5812900
834398-G	3500000
669429-G	3480580
733840-G	3180981
726830-G	2500000
573898-G	2306836
169199-G	2069818
733465-G	2018582
409757-G	1941109
708244-G	1833551
593357-G	1743031
643704-G	1666102
682705-G	1343976
478096-G	1313042
439997-G	1310626

So my thoughts would be that i would write a separate expression to sum the above to get the £90,561,496 then dived the two expressions by each other.

But when i do this it doesn't plot on the graph correct.

Here is my formula

Can anyone help...

Hi Andrew,

try with this formula instead:

=Aggr(sum({$ <FinYr={2011}>} FinAmt), FinMth) / sum(PY4_PY_End_Incurred)

and let me know if it works.
