Matplotlib legends in subplot

Question

I would like to put legends inside each one of the subplots below. I\'ve tried with plt.legend but it didn\'t work.

Any suggestions?

Thanks in advance :-)

This should work:

ax1.plot(xtr, color='r', label='HHZ 1')
ax1.legend(loc="upper right")
ax2.plot(xtr, color='r', label='HHN')
ax2.legend(loc="upper right")
ax3.plot(xtr, color='r', label='HHE')
ax3.legend(loc="upper right")
