Nope. It doesn't calculate standard deviations at the moment. It's a good idea though. I seem to recall there's a way to calculate a standard deviation on-the-fly that doesn't require all the values to be kept. Something about accumulating the squares of the values.

Time for me to upgrade probably. Odd. That was added a while ago. You'll need to upgrade to the head of svn trunk anyway to get the treemaps.
