python利用scatter绘画散点图代码示例

本篇文章小编给大家分享一下python利用scatter绘画散点图代码示例，文章代码介绍的很详细，小编觉得挺不错的，现在分享给大家供大家参考，有需要的小伙伴们可以来看看。

scatter绘画散点图代码如下：

import matplotlib.pyplot  as plt
plt.scatter(x,y,
                s = 20
                c='b'
                marker=‘o'
                cmap=None,
                norm=None,
                vmin=None,
                vmax=None,
                alpha=None,
                linewidths=None,
)

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
 
x=np.random.randint(0,10,10)
y=np.random.randint(0,10,10)
print(x)
print(y)
plt.scatter(x,y,s=50)默认形状圆点，颜色b 蓝色，大小50

out:

[5 1 5 3 1 5 0 5 4 7]

[8 2 7 7 8 6 3 8 5 9]

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
x = np.array([[0,0],[0,1],[1,1],[3,2],[-2,3],[1,2],[4,3]])
print(x)
plt.scatter(x[:,0],x[:,1],marker='x',color='k',s=20)#点的形状x，颜色黑色，大小20

out:

[[ 0 0]

[ 0 1]

[ 1 1]

[ 3 2]

[-2 3]

[ 1 2]

[ 4 3]]
