How to get details on Jetpack stats

This is a basic “how do I use this” question, everything is working properly.

The stats on the top toolbar above my blog often show a huge spike in visits during one hour. Is there any way I can go into the stats panel and break down visits by hour, or at least into chunks less than a day? I’m always curious to know why I get these spikes. Thanks!
