Python 散点图

1、示例1

import numpy as np
import matplotlib.pyplot as plt 

# 生成标准正态分布的样本 1000 个 x = np.random.randn(1000) # 绘制散点图 plt.plot(x, '.') plt.show()

2、示例2

import numpy as npimport matplotlib.pyplot as plt 

# 生成标准正态分布的样本 1000 个 x = np.random.randn(1000) # 绘制红色星号散点图, plt.scatter(np.arange(x.shape[0]), x, marker = '*', color = 'r') plt.show()
