chunk_data
(tr, samp_rate, state='mean')[source]¶ Downsample data for plotting.
Computes the maximum of data within chunks, useful for plotting waveforms or cccsums, large datasets that would otherwise exceed the complexity allowed, and overflow.
Parameters: - tr (obspy.core.trace.Trace) Trace to be chunked
- samp_rate (float) Desired sampling rate in Hz
- state (str) Either ‘Min’, ‘Max’, ‘Mean’ or ‘Maxabs’ to return one of these for the chunks. Maxabs will return the largest (positive or negative) for that chunk.
Returns:
