Plot zoom gets weird on stripping foil plots

See for example, Potassium 50 10+. At a minimum, these plots should be zoomed out enough to clearly show both A/Q acceptance regions. Also worth investigating whether the A/Q values reported are correct, given how extremely bunched they are in some cases.

Initial plots look good now, but zooming in and then unzooming unzooms the x axis to where dygraphs thinks it should set the x axis limits, not where we want them.
