How to read and plot seismic waveform data in Ascii format using Obspy?
If there is no direct function available, you can create a Trace/Stream object yourself.

The solution I use (example for one time series) is:


read the Ascii file into a numpy array
trace = obspy.core.Trace(data=numpy array, header=header dictionnary of your choice)
stream = obspy.core.Stream(traces=[trace])
stream.plot()
