Value Error when Trying to Plot Filtered Waveforms

[deanhystad]

The error message is pretty clear.

Error:
ValueError: x and y must have same first dimension, but have shapes (7461,) and (7460,)

The line that raises this error is.

plt.plot(t, tr.data)

So it looks like t and tr.data are not the same size. That points to this line being wrong.

t = np.arange(0, tr.stats.npts / tr.stats.sampling_rate, tr.stats.delta)

I would expect this to be:

t = np.arange(0, tr.stats.npts * tr.stats.delta, tr.stats.delta)

Print out the values for tr.stats.delta and tr.stats.sampling_rate. I don't think tr.stats.delta * tr.stats.sampling_rate == 1. The error is in your data, and a bad assumption in your program. Another, less likely possibility is that tr.stats.npts != len(tr.data).
