scatter绘制散点图

import numpy as np  
import matplotlib.pyplot as plt  

x = np.arange(1,10)  
y = x  
fig = plt.figure()  
ax1 = fig.add_subplot(111)  
ax1.set_title('Scatter Plot')   
plt.xlabel('X')  
plt.ylabel('Y')  
ax1.scatter(x,y,s=50,c =x,marker = 'o',label='xx',linewidth=x)  
plt.legend(loc='best')  
plt.savefig('scatter.png')
