Simple spectrogram

This example shows a spectrogram of the strain data from LIGO-Hanford around the time of GW150914.

gwpy-plot spectrogram \
    --gwosc \
    --ifo H1 \
    --start 1264316116 \
    --duration 32 \
    --epoch 1264316116.4 \
    --ymax 4000 \
    --interactive

The same command can be executed directly in Python as:

from gwpy.cli.gwpy_plot import main
main([
    'spectrogram',
    '--gwosc',
    '--ifo', 'H1',
    '--start', '1264316116',
    '--duration', '32',
    '--epoch', '1264316116.4',
    '--ymax', '4000',
    '--interactive',
])
