Question #227983 on Graphite changed:
https://answers.launchpad.net/graphite/+question/227983

    Status: Open => Solved

Tyson Tate confirmed that the question is solved:
To answer my own question:

What's happening here is that I'm moving from a less-accurate density of
points to a more-accurate density of points. Whisper does not
interpolate points in between the existing ones, so in the more-accurate
database, the new points are null.

The solution is to either re-work whisper-resize.py to add in the
missing points or simply use the keepLastValue() graphite filter to fill
in the missing points with the last point's value.
