Hello,
First let me say that I think Web Polygraph totally rocks. We've been using
it for over a year with our own scripted test system (dynamically creating
PG files for example), and would let to make even better use of it. And
thanks for 2.8, we didn't even realize that Polygraph was still being
developed.
I was hoping to better understand the histograms generated by a test. In
the raw output numbers, there are various histograms, but am not able to
really understand them properly.
basic.rptm.hist:
# bin min max count % acc%
817 1216 1391 8644 1.28 1.28
861 1392 1399 5795 0.86 2.15
The min, max, count and accuracy are easy to understand on their own, for
example from these to row I can say that 2.15% of the transactions took less
than 1400ms. I don't understand why the number of bins varies, the number
used for the bin, and why the count percentage varies so much from bin to
bin. The college stats books I have don't cover it. :(
What I would really like to is to graph the histogram itself for
visualization. I tried fooling around with the numbers in Excel awhile ago
to it to represent it properly and failed.
Anyone with insight on how the histograms are generated and references for
graphing them?
TIA!
Charlie
