I'm new to both python and stackoverflow, and I'm going over examples at matplotlib. I've searched for the solution to this problem with no luck, although I was able to locate a previously unanswered question in stackoverflow with the same issue.
Basically, I copied the code available from the examples at matplotlib; for instance:
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
def data_gen(t=0):
cnt = 0
while cnt < 1000:
cnt += 1
t += 0.1
yield t, np.sin(2*np.pi*t) * np.exp(-t/10.)
def init():
ax.set_ylim(-1.1, 1.1)
ax.set_xlim(0, 10)
del xdata[:]
del ydata[:]
line.set_data(xdata, ydata)
return line,
fig, ax = plt.subplots()
line, = ax.plot([], [], lw=2)
ax.grid()
xdata, ydata = [], []
def run(data):
# update the data
t, y = data
xdata.append(t)
ydata.append(y)
xmin, xmax = ax.get_xlim()
if t >= xmax:
ax.set_xlim(xmin, 2*xmax)
ax.figure.canvas.draw()
line.set_data(xdata, ydata)
return line,
ani = animation.FuncAnimation(fig, run, data_gen, blit=False, interval=10,
repeat=False, init_func=init)
plt.show()
I've run various animation examples in both Anaconda 2 (python 2.7) & 3 (python 3.5), and both give me a blank plot without animation. However, each animation works perfectly well in Enthought Canopy.
Is there something simple I'm missing when using spyder?
