Matplotlib y axis is not ordered

I'm getting data from serial port and draw it with matplotlib. But there is a problem. It is that i cannot order y axis values.

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()

Below graph is result of above code

This happened to me following the same tutorial.

My issue was the variables coming from my instrument were strings. Therefore, there is no order. I changed my variables to float and that fixed the problem

xs.append(float(FROM_INSTRUMENT))
