```python3 import control as ctl import matplotlib.pyplot as plt P = ctl.tf([1], [2, 1]) fig, ax = plt.subplots(2,2) ctl.nyquist_plot(P, ax=ax[1,0]) plt.show() ``` The nyquist plot always shows up in the botom right corner, no matter what index into `ax` I use. When I replace the nyquist with step, it shows up at the correct position (bottom left in this case): ```python3 fig, ax = plt.subplots(2,2) ctl.step_response(P).plot(ax=ax[1,0]) plt.show() ``` Version: control==0.10.1
