Add more granularity to graphs & data view

[GoogleCodeExporter]

Add an ability to view graphs & data in a 1 minute (or current collection 
interval set) granularity. So for example I can specify to view data from 
3.01.2013 13:23 - 3.01.2013 13:41

Do you know that you can click on a graph in the main report to zoom it? And 
that you can then use the slider at the top to zoom again?
Even if the image may be large, you can zoom on very fine details like that.

Yes, but the use cases I'm thinking off are:

1. I would like to see statistics (not charts) from for example one hour of the 
day (JSF actions, SQLs - in that specific period).

2. If I have a one big jump on the chart (like on the included screenshot), I 
cannot clearly differentiate between the usual data (as it all looks similar). 
It's not utterly important for identifying issues, but for example to print a 
nice report to the management with nice chart :). Anyway, the first use case is 
more important.

Unfortunately, only the statistics for each day are known and saved. That's 
part of the deal for the low overhead.
It is not planned to know the statistics for every hour or for every minute.
So this is won't fix, sorry.

You can still look at the mean and max times of the requests and at the charts, 
for that day.

This patch will not change anything for point 1 as said above.

For point 2, there is already an enhancement in v1.51 (soon to be released): 
"in a graph detail, a checkbox can now hide maximum values in the graph, so 
that average values are better displayed when much lower than the maximum 
(issue 368)".
And do not forget that graphs can also be zoomed.
