Holes in data break user flow over time #30

Closed nmalkin closed 12 years ago

When there are holes in the data (i.e., there is not a data point for every single day), the new user flow over time report (#18) breaks (problem parsing SVG with D3, no data written or rendered).

there is not a data point for every single day

Actually, that is not the issue.

The problem was that, in the data returned by the server, some days didn't have a value for every step. That is an indicator that 0 people completed the indicated step, but that needs to be stated explicitly.
