Subject Re: Distribution Graph and Graph
Date Mon, 04 Jan 2010 23:28:01 GMT
Ill have to verify but they would be the same only if you have exactly one
sample(which may be requested N number of times).

The Aggregate Graph plots the 90 % line per sample, so you would get a
different 90% line for each sample . What I mean is say your tests make 3
requests, request1, request2 and request3,(each requested say 100 times =
300 samples) the Aggregate graph would plot a 90% line considering each
request at a time , i.e. 100 samples at a time i.e. you would have 3 bars.
The Distribution graph on the other hand does not consider the sample and so
would consider all 300 requests and calculate the 90th percentile which
would only be the same in the special case that there is only one sampler.
In all other cases they will probably be different.
