5.2.10.1. eqcorrscan.utils.plotting.chunk_data¶
- eqcorrscan.utils.plotting.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:
