It would be awesome if we could knock an individual day out of the Jetpack stats just so that it doesn't interfere with your scale.
Let me explain.
I run bowmanvillezoo.com. We get between 1,000 and 4,000 hits a day. One day one of our former zookeepers put a link to us on Reddit and for two days we got more hits in a day than we get in some months.
Until those days "scroll off" our daily statistics, all of our "normal" days don't show any resolution and we can't tell easily whether traffic is up or down. If we could just click those two days and tell Jetpack to ignore them (even just for the purpose of scaling the graph) it would be greatly helpful.
