Question #222220 on Graphite changed:
https://answers.launchpad.net/graphite/+question/222220

    Status: Open => Answered

Nicholas Leskiw proposed the following answer:
If you have more than one datapoint per pixel, graphite will average all
datapoints and draw the average.

You may want to try the consolidateBy(foo.bar.baz,"max") function if you do
not like this behavior.
