无法在折线图的 Tkinter 窗口中获得所需的输出

Question

我是编码新手，我正在尝试使用 Matplotlib 类创建一个 Tkinter 窗口，该窗口允许我在单独的窗口中操作描绘 4 家公司两年内股价的折线图，这是我的代码写过：

from tkinter import *

from matplotlib.backends.backend_tkagg import (FigureCanvasTkAgg,NavigationToolbar2Tk)

from matplotlib.backend_bases import key_press_handler

from matplotlib.figure import Figure

import pandas as pd
root = Tk ()

data = pd.read_csv('C:\\Users\\Admin\\Desktop\\shares.csv')
df = data.iloc[:,:5]
print(df)
print()

fig = Figure( figsize = (20,5) , dpi = 100 )

ax1 = fig.add_subplot()

df.plot('Date',figsize = (20,5),  ax = ax1)

canvas = FigureCanvasTkAgg ( fig , root )

canvas.draw()

canvas.get_tk_widget().pack(side = TOP, fill = BOTH, expand = 1)

df.plot(kind = 'bar' , ax = ax1)

toolbar = NavigationToolbar2Tk(canvas, root)

toolbar.update()

canvas.get_tk_widget().pack(side = TOP, fill = BOTH, expand = 1)

def on_key(event):
    print('You Pressed {}'.format(event.key))
    key_press_handler(event, canvas, toolbar)
    
canvas.mpl_connect('key_press_event' , on_key)  
  
def Quit():
    root.quit()
    root.destroy()
    return

button = Button(root, text = 'QUIT' , command = Quit )

button.pack ()
root.mainloop()

这是我得到的输出：

而这是所需的图表：

对于如何解决此问题并改进我的代码，我将不胜感激。

谢谢:)

试试这个可能有用

df.plot(kind = 'line' , ax = ax1)

您正在绘制bar 并且您的预期输出是line 图表
