How to align matplotlib chart in its window?

I’m trying to align the chart to the top and left side of the window, eleminating all the whitespace there. Also the labels on the x axis are cut-off for some reason, even though I’m using tight_layout(). On top of this I have trouble removing the scientific notation from the y axis. (I want to display the original str or float held in the variable, If I use plt.yaxis.set_major_formatter(ScalarFormatter(useOffset=False)) I get an attribute arror: ‘matplotlib.pyplot’ has no attribute ‘yaxis’. This is what it looks like:

from binance.client import Client
import time, os, csv, datetime
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import matplotlib as mpl
from matplotlib.ticker import ScalarFormatter

client = Client(apikey, apisecret)

mpl.rcParams['toolbar'] = 'None'
fig = plt.figure(figsize=(4,3))'ggplot')
plt.rcParams['ytick.right'] = plt.rcParams['ytick.labelright'] = True
plt.rcParams['ytick.left'] = plt.rcParams['ytick.labelleft'] = False

x_vars = []
y_vars = []

def animate(i):
    global x_vars
    global y_vars
    if len(x_vars) > 30:
        x_vars = x_vars[-30:] 
        y_vars = y_vars[-30:] 

    current_time = client.get_server_time()
    current_price = client.get_symbol_ticker(symbol="XRPBTC")

    trstime = current_time["serverTime"] / 1000
    time = datetime.datetime.fromtimestamp(int(trstime)).strftime('%M:%S')


    plt.plot(x_vars, y_vars)
    plt.xticks(rotation = 45)  

ani = animation.FuncAnimation(fig, animate, interval=500)
