I'm looking for method that will allow me to update axis when my script is running but, I couldn't find it. For example:
import matplotlib.pyplot as plt
x = (1,2)
y = (1,2)
plt.plot(x,y, 'r-')
plt.show()
#here during run of program I want to clear axis with help of plt.cla() and update it
#new one
# x = (2,4)
# y = (2,4)
#plt.plot(x,y, 'b-')
To get the functionality you want you probably want to set matplotlib to interactive mode:
plt.ion()
Then call draw to update. For example:
import numpy
import time
x = (1,2)
y = (1,2)
plt.ion()
plt.plot(x,y, 'r-')
plt.draw()
for i in range(100):
print i
time.sleep(1)
plt.cla()
y = (numpy.random.normal(), numpy.random.normal())
plt.plot(x,y, 'r-')
plt.draw()
