Python MATPLOTY轴未排序

我从串口获取数据并用matplotlib绘制。但有一个问题。这是因为我无法对y轴值进行排序

import matplotlib.pyplot as plt
import matplotlib.animation as animation
from deneme_serial import serial_reader

collect = serial_reader()


fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
xs=[]
ys=[]

def animate(i, xs, ys):
    xs = collect.collector()[0]
    ys = collect.collector()[1]
    ax.clear()
    ax.plot(xs)
    ax.plot(ys)
    axes=plt.gca()

    plt.xticks(rotation=45, ha='right')
    plt.subplots_adjust(bottom=0.30)
    plt.title('TMP102 Temperature over Time')
    plt.ylabel('Temperature (deg C)')

ani = animation.FuncAnimation(fig, animate, fargs=(xs,ys), interval=1000)
plt.show()

下图是上述代码的结果
