Einbetten von Matplotlib und Slider in Tk-Fenster

Question

Ich versuche, ein Matplotlib-Fenster in eine Tkinter-GUI einzubetten, aber ich habe Probleme, das "Slider" -Widget angezeigt zu bekommen. Der folgende Code zeigt zwar ein eingebettetes Bild, aber das Bild selbst verhält sich wie ein Schieberegler, wenn Sie darauf klicken!

ich die Ideen von dieser Frage

Placing plot on Tkinter main window in Python

import matplotlib 
matplotlib.use('TkAgg') 
import numpy as np 
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg 
from matplotlib.figure import Figure 
from matplotlib.widgets import Slider 
import Tkinter as tk 


class Embed: 

    def __init__(self, root): 

     self.root = root 
     self.plot = Plotting(self.root) 
     self.a = np.array([[1,2,3],[2,3,4],[3,4,5]]) 
     self.b = np.array([[1,2,3],[4,5,6],[7,8,9]]) 
     self.ctuple = (self.a,self.b) 
     self.cube = np.dstack(self.ctuple) 
     self.button = tk.Button(root, text="check", command=lambda: self.plot.plot(self.cube)) 
     self.button.pack() 

class Plotting: 

    def __init__(self, root): 

     self.root = root 

    def plot(self, cube, axis=2, **kwargs): 

     fig = Figure(figsize=(6,6)) 
     ax = fig.add_subplot(111) 
     s = [slice(0,1) if i == axis else slice(None) for i in xrange(3)] 
     im = cube[s].squeeze() 

     l = ax.imshow(im, **kwargs) 
     canvas = FigureCanvasTkAgg(fig, self.root) 
     canvas.get_tk_widget().pack() 
     canvas.draw() 
     slider = Slider(ax, 'Axis %i index' % axis, 0, cube.shape[axis] - 1, 
        valinit=0, valfmt='%i') 

     def update(val): 
      ind = int(slider.val) 
      s = [slice(ind, ind + 1) if i == axis else slice(None) 
      for i in xrange(3)] 
      im = cube[s].squeeze() 
      l.set_data(im, **kwargs) 
      canvas.draw() 

     slider.on_changed(update) 

if __name__ == '__main__': 

    root = tk.Tk() 
    app = Embed(root) 
    root.mainloop() 
    root.destroy() 

jede Hilfe ist sehr geschätzt unter Verwendung haben versucht!

Ich weiß nicht, was Ihr Code tut. Ich habe versucht, es so wenig zu ändern, wie ich kann:

import matplotlib 
matplotlib.use('TkAgg') 
import numpy as np 
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg 
from matplotlib.figure import Figure 
import Tkinter as Tk 
import matplotlib.pyplot as plt 


class Embed: 

    def __init__(self, root_): 
     self.root = root_ 
     self.a = np.array([[1, 2, 3], [2, 3, 4], [3, 4, 5]]) 
     self.b = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) 
     self.c = np.array([[1, 4, 7], [4, 7, 10], [7, 10, 13]]) 
     self.ctuple = (self.a, self.b) 
     self.cube = np.dstack(self.ctuple) 
     self.cube = np.dstack([self.cube, self.c]) 
     self.plot = Plotting(self.root, self.cube) 
     self.button = Tk.Button(root, text="check", command=lambda: self.plot.plot()) 
     self.button.pack() 


class Plotting: 
    def __init__(self, root, cube): 
     self.root = root 
     self.fig = Figure(figsize=(6, 6)) 
     self.ax = self.fig.add_subplot(111) 
     self.cube = cube 
     self.slider = Tk.Scale(
      self.root, from_=0, to=cube.shape[2] - 1, resolution=0.01, orient=Tk.HORIZONTAL, command=self.update 
     ) 
     # self.slider.on_changed(self.update) 
     self.slider.pack() 
     self.plotted = False 
     self.l = None 
     self.canvas = None 
     plt.show() 

    def plot(self, **kwargs): 
     self.plotted = True 
     s = [slice(0, 1) if i == 2 else slice(None) for i in xrange(3)] 
     im = self.cube[s].squeeze() 
     self.l = self.ax.imshow(im, **kwargs) 
     self.canvas = FigureCanvasTkAgg(self.fig, self.root) 
     self.canvas.get_tk_widget().pack() 
     self.canvas.draw() 

    def update(self, val): 
     ind = int(self.slider.get()) 
     s = [slice(ind, ind + 1) if i == 2 else slice(None) for i in xrange(3)] 
     if self.plotted: 
      im = self.cube[s].squeeze() 
      self.l.set_data(im) 
      self.canvas.draw() 


if __name__ == '__main__': 
    root = Tk.Tk() 
    app = Embed(root) 
    root.mainloop() 
    root.destroy()
