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]]
