Error when interpolating datasets, each with different amount of detectors

[153957]

Can't plot Temperature (2 sensors) vs pulseheight (4 detectors).
Error when doing a scatter plot of Temperature vs Pulseheight:

[Error] TypeError: undefined is not an object (evaluating 'data.filter')
remove_error_values (jquery.jsparc.js, line 1312)
(anonymous function) (data_retrieval.html, line 211)

handle (jquery-1.10.2.min.js, line 4)

Works fine for 2 detector station, but then inside temp vs detector 1 and outside temp vs detector 2..
