https://www.black-holes.org/waveforms/docs.html

there dataset in file think describes waveform want plot. problem don't know how data set. have gotten far doing:

import numpy np import h5py pylab import plot,show  f = h5.py.file("rhoverm_asymptotic_geometricunits.h5","r") ks = f.keys()

from here don't know how create x , y axis go plot function. assuming need attribute belongs h5py module, not sure if using right terminology. appreciated.

try this:

import matplotlib.pyplot plt import h5py  f = h5py.file("rhoverm_asymptotic_geometricunits.h5", "r") data = f['extrapolated_n2.dir/y_l2_m-1.dat'] plt.plot(data[:, 0], data[:, 1], label='column1') plt.plot(data[:, 0], data[:, 2], label='column2') plt.legend() plt.show()
