Title: Dynamic Paths would sometimes render incorrectly.

We were storing the referenceFrame property on each interval rather than the interval.data property. When an interval is split (because of new incoming data) the property was lost. We need to stre the referenceFrame on the data property instead.

@mrmattf here is the fix you were looking for. Merge this if you're happy.
