尽管我仍然认为您应该使用bokeh，但我将告诉您如何使用matplotlib来实现它。在
它不能工作的问题是matplotlib的事件循环不是活动的，因此它不能消化窗口事件(比如close或resize)。不幸的是，它不可能从外部引发这种消化。您需要做的是使用matplotlib的动画系统。
实际上，您的代码已经为它做好了充分的准备，因此您可以使用FuncAnimation。在import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
import math
# generate data
x = [0.1*_a for _a in range(1000)]
y = map(lambda x : math.sin(x), x)
# don't need ion, we're using block=True (see end of code)
fig, ax = plt.subplots()
fig.show()
# ax = plt.gca()
lines, = ax.plot([], [])
# ax.set_ylim(-1, 1)
ax.grid()
MAX_N_DATA = 100
x_data = []
y_data = []
def showdata(i):
# New data received
x_data.append(x[i])
y_data.append(y[i])
# limit data length
if x_data.__len__() > MAX_N_DATA:
x_data.pop(0)
y_data.pop(0)
# Set Data
lines.set_xdata(x_data)
lines.set_ydata(y_data)
# The data limits are not updated automatically.
ax.relim()
# with tight True, graph flows smoothly.
ax.autoscale_view(tight=True, scalex=True, scaley=True)
# draw will be called by the animation system
# instead of time.sleep(0.01) we use an update interval of 10ms
# which has the same effect
anim = FuncAnimation(fig, showdata, range(len(x)), interval=10, repeat=False)
# start eventloop
plt.show(block=True)
