Bug: Multiple time series, different time stamps, rendering error

[tomhampshire]

I have based my project on the finance template. I have two data sources, which sample at independent rates (although both at regular intervals). When visualised as separation component, everything is displayed correctly (see image 1). However, using the zooming interaction on any section of the graph results in the display of the two data sources incorrectly: the data is out-of-sync, or staggered with respect to each other (see image 2).
I will create a temporary solution by interpolating the values, and displaying using the same set of time stamps, but a fix for this problem would be nice.
Amazing software library by the way.
