Python 增加y字体Matplotlib

我试图从我的图形增加我的Y字体，但它不起作用.

我的代码是:

import tkinter as tk 
import matplotlib.pyplot as plt 
from matplotlib.figure import Figure 
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg 
from matplotlib import animation 
import random

# Create the Tkinter window root = tk.Tk() root.geometry('400x100')
fig1, b1 = plt.subplots(figsize=(10, 0.5), dpi = 80)
#b1 = fig1.add_subplot(111)


fig2, b2 = plt.subplots(figsize= (10, 0.5), dpi = 80)
#b2 = fig2.add_subplot(111)


def grafico_1 (i):
    global b1
    global nume
    global valu
    global fig1
    global y_fix
    global x

    x = []
    y_fix = []
    ws = ['WIRE']

    for valu in range (1, 6):
        nume = random.randint(1, 10)
        x.append(nume)
    #print(x)

    #Primeira camada do grafico 
    if int(x[0]) < 3:
        y_fix.append(int(x[0]), )
        #print(f'Lista de y_n ,e {y_n}')
        b1.barh(ws, int(x[0]), color = 'green')
        

    if int(x[0]) >= 3 and int(x[0]) < 6:
        y_fix.append(x[0])
        b1.barh(ws, int(x[0]), color='yellow')
        

    if int(x[0]) >= 6:
        y_fix.append(x[0])
        b1.barh(ws, int(x[0]), color='red')
        

    #Segunda camada:
    for c in x[1:]:
        if int(c) < 3:
            b1.barh(ws, int(c), color= 'green', left=y_fix)
            y_fix.append(int(c))
            jump = sum(y_fix)
            y_fix = []
            y_fix.append(jump)
            
            
        if int(c) > 3 and int(c) < 5:
            b1.barh(ws, int(c), color='yellow', left= y_fix)
            y_fix.append(int(c))
            jump = sum(y_fix)
            y_fix = []
            y_fix.append(jump)
            

        if int(c) >= 5:
            b1.barh(ws, int(c), color='red', left= y_fix)
            y_fix.append(int(c))
            jump = sum(y_fix)
            y_fix = []
            y_fix.append(jump)

            y_fix2.append(jump2)


    #plt.show()

ani1 = animation.FuncAnimation(fig1, grafico_1, interval = 3000, frames=100) ani2 = animation.FuncAnimation(fig2, grafico_2, interval = 3000, frames=100)

# Embed the figures into Tkinter using FigureCanvasTkAgg canvas1 = FigureCanvasTkAgg(fig1, master=root) canvas1.get_tk_widget().place(x= 300, y= 460)
