Как сгладить график?

Question

[Programist18946]

не могу сгладить график, подскажите пожалуйста

import numpy as np
import matplotlib.pyplot as plt

def fun_1(x):
    if x > -4 and x <= -2:
        return 2
    if x > -2 and x <= 0:
        return abs(x)
    if x > 0 and x <= 2:
        return x
    if x > 2 and x <= 4:
        return 2


def fun(t):
    tmp = 0
    for k in range(1, 4):
        tmp += (1 / (k ** 2)) * (np.cos(((np.pi * k) / 2)) - 1) * (np.cos((np.pi * k * t) / 4))
    return ((8 / (np.pi ** 2)) * tmp) + 3 / 2
z = []
y = []
z1 = []
y1 = []
for t in range(-4, 5):
    z.append(t)
    y.append(fun(t))
for x in range(-6, 5):
    z1.append(x)
    y1.append(fun_1(x))

z_sm = np.array(z)
y_sm = np.array(y)


plt.plot(z_sm, y_sm)
plt.plot(z1, y1)
plt.grid()
plt.show()

import numpy as np
import matplotlib.pyplot as plt
from scipy.interpolate import make_interp_spline
...
x_sm = np.array(z)
y_sm = np.array(y)
X_Y_Spline = make_interp_spline(x_sm, y_sm)

X_ = np.linspace(x_sm.min(), x_sm.max(), 500)
Y_ = X_Y_Spline(X_)

plt.plot(X_, Y_)
