我已經(jīng)構(gòu)建了簡單的 tkinter GUI?，F(xiàn)在，我嘗試可視化 3 個不同的圖形（通過使用不同的變量調(diào)用相同的函數(shù)）并將它們放置在 GUI 的 3 個不同行中。當我這樣做時，我遇到了兩個問題：每次運行腳本（interface.py）時，我都會得到 2 個窗口 - GUI 和外部圖形的窗口。如何擺脫第二個？我無法可視化所有 3 個圖表。腳本在顯示第一個腳本后停止。我相信這是因為第一個圖在循環(huán)中工作（迭代大量數(shù)據(jù)點）。有什么解決辦法嗎？界面：# -*- coding: utf-8 -*-"""Created on Tue Oct 6 10:24:35 2020@author: Dar0"""from tkinter import * #import tkinter modulefrom visualizer import main #import module 'visualizer' that shows the graph in real timeclass Application(Frame): ''' Interface for visualizing graphs, indicators and text-box.

關鍵是pyplot當你想在內(nèi)部繪制時不要使用，matplotlib.figure.Figure
下面是一個最小示例，它沿著我在您的代碼中看到的小部件繪制了 3 個獨立的圖表Text：
import pandas as pd
import numpy as np
import tkinter as tk
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2Tk
from matplotlib.figure import Figure
? ??
class Graph(tk.Frame):
? ? def __init__(self, master=None, title="", *args, **kwargs):
? ? ? ? super().__init__(master, *args, **kwargs)
? ? ? ? self.fig = Figure(figsize=(4, 3))
? ? ? ? ax = self.fig.add_subplot(111)
? ? ? ? df = pd.DataFrame({"values": np.random.randint(0, 50, 10)}) #dummy data
? ? ? ? df.plot(ax=ax)
? ? ? ? self.canvas = FigureCanvasTkAgg(self.fig, master=self)
? ? ? ? self.canvas.draw()
? ? ? ? tk.Label(self, text=f"Graph {title}").grid(row=0)
? ? ? ? self.canvas.get_tk_widget().grid(row=1, sticky="nesw")
? ? ? ? toolbar_frame = tk.Frame(self)
? ? ? ? toolbar_frame.grid(row=2, sticky="ew")
? ? ? ? NavigationToolbar2Tk(self.canvas, toolbar_frame)
? ??
root = tk.Tk()
for num, i in enumerate(list("ABC")):
? ? Graph(root, title=i, width=200).grid(row=num//2, column=num%2)
text_box = tk.Text(root, width=50, height=10, wrap=tk.WORD)
text_box.grid(row=1, column=1, sticky="nesw")
text_box.delete(0.0, "end")
text_box.insert(0.0, 'My message will be here.')
root.mainloop()
