Title: Make moving(Average|Median) generate complete graphs

moving(Average|Median) used to start graphs with a bunch of None's due
to missing data. Instead, fetch the missing data and complete the graph.

(pull request 52 requests this for master, this is a straight cherry-pick of that commit onto 0.9.x)
