"Number of Users" vs "Number of Actions" is broken, because user records output by the current munger script do not have a numEvents property.
However, this was not a very useful plot anyway, so I think we should just get rid of number-of-actions, replacing it with median-actions-per-user and mean-actions-per-user (neither of which can be meaningfully plotted against number-of-users).
