Question

我正在尝试使用tkinter创建一个GUI，它会在出现提示时绘制多个绘图。现在我的代码工作，它将所有图形绘制到一个图形上。我想在同一个GUI中将图表绘制在不同的图形上。

这是我的代码，它绘制了同一个tkinter图中的所有图形：

import myModule
from myModule import *
import SA_apis
from SA_apis import *
import matplotlib
matplotlib.use("TkAgg")
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg,   NavigationToolbar2TkAgg
from matplotlib.figure import Figure
import tkinter as tk
from tkinter import ttk
from matplotlib import pyplot as plt

LARGE_FONT= ("Verdana", 12)
NORM_FONT= ("Verdana", 10)
SMALL_FONT= ("Verdana", 8)
plt.style.use("dark_background")
plt.style.use("seaborn-bright")

def popupmsg(msg):
    popup = tk.Tk()
    popup.wm_title("Menu")
    label = ttk.Label(popup, text=msg, font=NORM_FONT)
    label.pack(side="top", fill="x", pady=10)
    B1 = ttk.Button(popup, text="Okay", command = popup.destroy)
    B1.pack()
    popup.mainloop()


class TkGraph(tk.Tk):
    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)
        tk.Tk.wm_title(self, "TkGraph")

        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand = True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        menubar = tk.Menu(container)
        filemenu = tk.Menu(menubar, tearoff=0)
        filemenu.add_command(label="New", command = lambda: popupmsg("This is not yet supported"))
        filemenu.add_command(label="Add", command = lambda: popupmsg("This is not yet supported"))
        filemenu.add_command(label="Exit", command=quit)
        menubar.add_cascade(label="File", menu=filemenu)
        tk.Tk.config(self, menu=menubar)

        parameter = tk.Menu(menubar, tearoff=0)
        parameter.add_command(label="Selection", command = lambda: popupmsg("This is not yet supported"))
        menubar.add_cascade(label="Parameter", menu=parameter)
        tk.Tk.config(self, menu=menubar)

        timemenu = tk.Menu(menubar, tearoff=0)
        timemenu.add_command(label="Selection", command = lambda: popupmsg("This is not yet supported"))
        menubar.add_cascade(label="Time", menu=parameter)
        tk.Tk.config(self, menu=menubar)

        helpmenu = tk.Menu(menubar, tearoff=0)
        helpmenu.add_command(label="Selection", command = lambda: popupmsg("This is not yet supported"))
         menubar.add_cascade(label="Help", menu=parameter)
        tk.Tk.config(self, menu=menubar)

         self.frames = {}
        for F in (StartPage, PageOne):
            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")
         self.show_frame(StartPage)
    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()

class StartPage(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self,parent)
        label = tk.Label(self, text="Home", font=LARGE_FONT)
        label.pack(pady=10,padx=10)
        button1 = ttk.Button(self, text="Graph",
        command=lambda: controller.show_frame(PageOne))
        button1.pack()


 class PageOne(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = tk.Label(self, text="Graph", font=LARGE_FONT)
        label.pack(pady=10,padx=10)
        button1 = ttk.Button(self, text="Back to Home",
                        command=lambda: controller.show_frame(StartPage))
        button1.pack()

    """This is the code for the plotted graph, for each parameter you wish to plot you need to have a seperate x, y coordinate system.
    You got the amount of points for each parameter on SA_apis now you just paste that number in the code."""

    #Graph Code
    x = (g[0].time[:111673])
    y = (g[0].data.f[:111673])
    x2 = (h[0].time[:142642])
    y2 = (h[0].data.f[:142642])
    x3 = (j[0].time[:134970])
    y3 = j[0].data.f[:134970]
    x4 = (p[0].time[:147542])
    y4 = (p[0].data.f[:147542])
    plt.subplot()
    fig = plt.figure()

    """For each parameters x,y coordinates you will need a seperate  plt.plot()"""
    plt.plot(x, y)
    plt.plot(x2, y2)
    plt.plot(x3, y3)
    plt.plot(x4, y4)
    #descr = (g[0].descr)
    plt.title('(descr)', fontsize = 15)
    plt.xlabel('Time', fontsize=12)
    plt.ylabel('Data', fontsize=12)
    plt.grid(linestyle = 'dashed')   

    canvas = FigureCanvasTkAgg(fig, self)
    canvas.show()
    canvas.get_tk_widget().pack(side=tk.BOTTOM, fill=tk.BOTH, expand=True)

    toolbar = NavigationToolbar2TkAgg(canvas, self)
    toolbar.update()
    canvas._tkcanvas.pack(side=tk.TOP, fill=tk.BOTH, expand=True)

app = TkGraph()
app.mainloop()

我尝试将图表分开：

    x = (g[0].time[:111673])
    y = (g[0].data.f[:111673])
    plt.plot(x, y)
    plt.title('(descr)', fontsize = 15)
    plt.xlabel('Time', fontsize=12)
    plt.ylabel('Data', fontsize=12)
    plt.grid(linestyle = 'dashed')
    fig = plt.figure()

    x2 = (h[0].time[:142642])
    y2 = (h[0].data.f[:142642])
    plt.plot(x2, y2)
    plt.title('(descr)', fontsize = 15)
    plt.xlabel('Time', fontsize=12)
    plt.ylabel('Data', fontsize=12)
    plt.grid(linestyle = 'dashed')
    fig = plt.figure()

    x3 = (j[0].time[:134970])
    y3 = (j[0].data.f[:134970])
    plt.plot(x3, y3)
    plt.title('(descr)', fontsize = 15)
    plt.xlabel('Time', fontsize=12)
    plt.ylabel('Data', fontsize=12)
    plt.grid(linestyle = 'dashed')
    fig = plt.figure()

    x4 = (p[0].time[:147542])
    y4 = (p[0].data.f[:147542])
    plt.plot(x4, y4)
    plt.title('(descr)', fontsize = 15)
    plt.xlabel('Time', fontsize=12)
    plt.ylabel('Data', fontsize=12)
    plt.grid(linestyle = 'dashed')
    fig = plt.figure()

但这很乏味，并且不会导致在同一个tkinter窗口中绘制所有四个图形。这会导致并清空tkinter。

我的问题是：如何在同一个tkinter窗口中绘制多个图形，但是在不同的图形中。理想情况下，它们会彼此相邻绘制，我不想创建另一个窗口。我需要同时查看所有图表以进行比较。

Answer 1

您只需使用Frame小部件。

您可以在同一窗口中拥有多个框架，以便为每个图形创建所需的每个框架，并以这种方式使用它们。

看到你已经在使用框架，你应该不难设置。

Answer 2

你需要在subplot方法中输入参数。

plt.subplot(421)
plt.xlabel('Time in seconds')
plt.ylabel('Amplitude')
plt.title('%s HeartBeat ..' % beat_file1)
plt.plot(timeArray1, Y_filtered1)

plt.subplot(422)
plt.xlabel('Time in seconds')
plt.ylabel('Amplitude')
plt.title('%s HeartBeat ..' % beat_file2)
plt.plot(timeArray2, Y_filtered2)

在同一窗口内的单独tkinter图中绘制多个图形
