Ask HN: Best way to visualize / analyze website stats in realtime?

Say I'm running an e-commerce website.

I want to be able to (data updated once a minute):

- See how many orders we're getting. I want to be able to answer questions like "are we taking more orders this evening than normal?" and "what hour do we make the most profit each day?"

- How many people people did X? (where X could be commenting, playing games, registering, tweeted about us, etc)

There's a lot of analytics software up there, but not many let you break data down into minute or hour chunks of time. Also, we'd want to be able to customize what data is being monitored.

We already use Chartbeat and Google Analytics. Chartbeat doesn't let you customize data (so we couldn't see how much profit we make per hour, for example), and Analytics isn't realtime at all.
