一、打开python

新建一个pathon项目。 

二、代码 

# -*- coding: utf-8 -*-
import matplotlib.pyplot as plt

names = ['1', '2', '3', '4', '5', '6']
x = range(len(names))
plt.rcParams['font.sans-serif'] = ['SimHei']  # 显示汉字

y_1 = [2, 3, 4, 5, 6, 1]
y_2 = [3, 4, 5, 6, 1, 2]   //y轴的值
y_3 = [4, 5, 6, 1, 2, 3]

plt.plot(x, y_1, color='orangered', marker='o', linestyle='-', label='A')
plt.plot(x, y_2, color='blueviolet', marker='D', linestyle='-.', label='B')
plt.plot(x, y_3, color='green', marker='*', linestyle=':', label='C')
plt.legend()  # 显示图例
plt.xticks(x, names, rotation=45)
plt.xlabel("X轴坐标")  # X轴标签
plt.ylabel("Y轴坐标")  # Y轴标签
plt.show()
