python matplotlib -如何确保x轴值与源数据相同

import matplotlib.pyplot as plt

x = [1, 2, 3, 4, 5]
y = [10, 20, 30, 40, 50]

plt.plot(x, y)

plt.xticks(range(len(x)), x)  # 设置x轴刻度值为源数据的值

plt.show()

import matplotlib.pyplot as plt

x = [1, 2, 3, 4, 5]
y = [10, 20, 30, 40, 50]

plt.plot(x, y)

plt.gca().set_xticks(x)  # 设置x轴刻度值为源数据的值

plt.show()

import matplotlib.pyplot as plt

x = [1, 2, 3, 4, 5]
y = [10, 20, 30, 40, 50]

plt.plot(x, y)

plt.xticks(x, x)  # 设置x轴刻度标签为源数据的值

plt.show()
