我通过三个传感器节点的套接字连接向我提供数据,每个子图有三个子图,分别用于温度,电压和湿度值。临时子图应绘制每个节点的温度值。同样适用于湿度和电压。这是我写的代码:
import socket
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import pickle
fig = plt.figure()
temp_plot = fig.add_subplot(3,1,1)
volt_plot = fig.add_subplot(3,1,2)
pres_plot = fig.add_subplot(3,1,3)
maclist=['xyz01','xyz02','xyz03']
temp=[]
volt=[]
time=[]
pres=[]
ip = 'server IP address'
sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
sock.connect((ip,10030))
print 'connection established to server...'
def animate(i):
global sock
info = sock.recv(1024)
info = pickle.loads(info)
ind = maclist.index(info['MAC'])
if len(temp[ind]) == 10: #to make sure every time 10 points are plotted
temp[ind].pop(0)
time[ind].pop(0)
volt[ind].pop(0)
pres[ind].pop(0)
temp[ind].append(info['TEMP'])
time[ind].append(info['TIME'])
volt[ind].append(info['VOLT'])
pres[ind].append(info['PRES'])
temp_plot.clear()
volt_plot.clear()
pres_plot.clear()
for i in range(len(maclist)):
temp_plot(time[i],temp[i])
volt_plot(time[i],volt[i])
pres_plot(time[i],pres[i])
if __name__ == '__main__' :
ani = animation.FuncAnimation(fig,animate,interval = 100)
plt.show()
info = { 'MAC': 'xyz01', 'TIME':21.4131, 'TEMP':27.0, 'VOLT':2.5, 'PRES':892}
temp,volt,time和pres是包含子列表的列表, 因为ex-temp [0]包含来自node0的温度值列表。
这段代码给了我一个错误,我怀疑是因为试图在循环中绘图
“temp_plot(时间[I],温度[I])
TypeError:'AxesSubplot'对象不是 可骂'
任何人都可以帮助我这个
答案 0 :(得分:0)
temp_plot
是您要绘制的子图。你不能自己调用子图。就像你不写plt(x,y)
或ax(x,y)
,而是写plt.plot(x,y)
或ax.plot(x,y)
一样;在这里你需要
temp_plot.plot(time[i],temp[i])
volt_plot.plot(time[i],volt[i])
pres_plot.plot(time[i],pres[i])
