沒接觸過這個模組。但是畫曲線用過其他的供參考。

import numpy as np

import matplotlib.pyplot as plt

x = np.linspace(-10, 10, 10000)

a = np.sin(x)

b = np.cos(x)

c = np.tan(x)

d = np.log(x)

plt.figure(figsize=(8, 4))

plt.plot(x, a, label="$sin(x)$", color="green", linewidth=1)

plt.plot(x, b, label="$cos(x)$", color="blue", linewidth=1)

plt.plot(x, c, "b--", label="$tan(x)$", color="red", linewidth=1)

plt.plot(x, d, "b--", label="$log(x)$", color="grey", linewidth=1)

plt.xlabel("Time(s)")

plt.ylabel("Volt")

plt.title("PyPlot")

plt.xlim(-10, 10)

plt.ylim(-5, 5)

plt.legend()

plt.show()
