如何使用matplotlib显示两个数字？

pip install matplotlib

import matplotlib.pyplot as plt

x = [1, 2]
y = [1, 4]

plt.plot(x, y)
plt.xlabel('x-axis')
plt.ylabel('y-axis')
plt.title('Line Chart for Two Numbers')

plt.show()

import matplotlib.pyplot as plt

x = [1, 2]
y = [1, 4]

plt.plot(x, y)
plt.xlabel('x-axis')
plt.ylabel('y-axis')
plt.title('Line Chart for Two Numbers')

plt.show()
