Vinay,
At the risk of repeating the same thing, I still believe that you are
complicating what is essentially a simple item.
You want to get the dates of previous spike and next spike.
Next Spike wont be shown unless you have data for the future as well. I hope
that you are not implying that AB give out future date of spike if you dont
have data itself
For example, if there is a spike on say 15th Jan and another spike on say
15th April and you are exploring using Date Range from 15March to 15 March,
you want to get the number of days btw 15th Jan and 15th March and likewise
from 15th March to 15th April.
This output gives 2 range of days. If you just explore using syntax already
provided on 15th April, you get the combined number of days. If you combine
the first 2 output, it matches perfectly with this.
I just dont really understand why you need to calculate the future from past
rather than simply calculating the difference of dates.
Cheers
Prashanth

both in the 'from' and in the 'to' boxes of 'Range' in 'Automatic Analyssis'
and press the 'Explore' button, maybe it will show to me that the next
volume spike took place 9 days after 22nd Jan 2008.
