Weird Latency Graphs

Hi,

I see some of the latency graphs showing up pretty weird

Lets look at the one of them:

You can see with sparkline I am looking at the start and the end of this
very steep increase
It looks visually the latency is about 2x larger from the start to the end
but as you can see what
mouse-over shows it is 1:27 in both cases

I see similar behavior in others. It does not look to me we're forcing
the minimum on the sparkline to always be zero.
