利用pythonnumpy+matplotlib绘制股票k线图的方法-创新互联

一、python numpy + matplotlib 画股票k线图

import numpy as np  
from matplotlib import pyplot as plt  
from matplotlib import animation
 
fig = plt.figure(figsize=(8,6), dpi=72,facecolor="white")
axes = plt.subplot(111)
axes.set_title('Shangzheng')

	r = requests.get(url)
	data = r.content[21:-3].decode('gbk').encode('utf8').split(',')
	alldata.append(data[3])
	axes.set_ylim(float(data[5]), float(data[4]))
	return alldata

 	line.set_data(x, y)
 	return line
 
anim=animation.FuncAnimation(fig, animate, init_func=init, frames=10000, interval=5000)
 
plt.show()
