如何为matplotlib.animate设置标签和轴限制？

Question

我正在编写以下脚本来获取GBP-EUR汇率并使用matplotlib动态绘制它，因为它代表脚本无限运行并更新图形，但标签和轴限制没有出现，我怎么会做这个？

`#!/usr/bin/env python
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
from yahoo_finance import Currency
from time import time
pound = Currency('GBPEUR')
prices = []
times = []
start = time()
n = 0
def animate(i):
    pound.refresh()
    prices.append(float(pound.get_bid()))
    times.append((time() - start))
    plt.axis([0,max(times),0,(max(prices)+5)])
    plt.xlabel('Time since start, Seconds')
    plt.ylabel('Pound-Euro conversion rate')
    ax1.clear()
    ax1.plot(times,prices)
while True:
    pound.refresh()
    prices.append(float(pound.get_bid()))
    times.append((time() - start))
    fig = plt.figure()
    ax1 = fig.add_subplot(1,1,1)
    ani = animation.FuncAnimation(fig, animate, interval=1)
    plt.show()`

我自己想出了这一点，删除了排序ax1.clear()的行。
