I am experiencing weird issue. My code is as below.
import control
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.patches import *
num = 240
den = [1, 10, -11, -180]
# Creating a transfer function G = num/den
G = control.tf(num, den)
# w = np.logspace(-3, 3, 5000)
control.nyquist_plot(G, omega=None, Plot=True, labelFreq=0)
It creates wierd arrow size as shown in below figure. Is there any way to reduce the size of arrow?
