Help Proxima understand loss of precision in box-select in bokeh

[ProximaDas]

This is helping me understand how we are losing precision on the earthquake data with the javascript callback. Can you give me some pointers on where I can read up about this?

The entire issue is just because some points in the time-series are outside of the y-bounds of the box. So, those points aren't included in the timeseries. Unmodified, then, an FFT won't even work (it relies on regularly sampled data). And, if you interpolate, you will interpolate a different point than the one that's outside the y-bounds, as you'll be interpolating between two points that are inside the y-bounds.
