tkinter和matplotlib画布显示，但不显示导航工具栏和图形标题

标签： python matplotlib tkinter title

我正在创建一个程序，将matplotlib包含到tkinter中。该程序的大部分工作包括显示图形的画布，但是，图形标题，导航工具栏和xy图例不显示。我想知道的代码部分就在脚本的底部：

toolbar = NavigationToolbar2TkAgg( canvas, root ) 
toolbar.update() 
canvas._tkcanvas.grid(row=9,column=0)
plt.xlabel('x label')
plt.ylabel('y label')
plt.title('Graph')
plt.show()

有没有人有任何建议？任何帮助都将非常感谢！

# Adding line graph to Canvas--------------------------------------------

我知道这个答案可能会有点晚，但我最近偶然发现了这个问题，而且你可以做些什么：

对于工具栏的问题我可以参考这个问题： Displaying Matplotlib Navigation Toolbar in Tkinter via grid

NavigationToolbar在内部调用.pack（）并且pack（）和grid（）不能一起工作。但是你可以在根框架上创建一个Tk.Frame并将工具栏打包在那里：

ToString()

如果要显示轴标签，请调用plt.figure而不是图。这适用于我的情况：

toolbar_frame = Tk.Frame(root)
toolbar_frame.grid(row=9,column=0)
toolbar = NavigationToolbar2TkAgg(canvas, toolbar_frame) 
toolbar.update()

您编写代码的方式对我的设置没有影响，因此我做了一些其他更改。结果如下：

fig = plt.figure(figsize=(5,4), dpi=100)

我认为您使用了许多不必要的导入，这些导入可能会相互冲突，对我来说就是这种情况 from matplotlib import pyplot as plt from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg #from matplotlib.figure import Figure #from Tkinter import * import Tkinter as Tk #import numpy as np #import math #import matplotlib #matplotlib.use('TkAgg') #from matplotlib.backend_bases import key_press_handler #import sys root = Tk.Tk() #Interface----------------------------------------------------------- title_label = Tk.Button(root,text = "Add graph title", padx=2,pady=2) xlabel = Tk.Button(root,text = "Add X values ", padx=2,pady=2) ylabel = Tk.Button(root,text = "Add Y values ", padx=2,pady=2) nameXaxis = Tk.Button(root,text = "Name X axis ", padx=2,pady=2) nameYaxis = Tk.Button(root,text = "Name Y axis ", padx=2,pady=2) meanLabel = Tk.Button(root,text = "Mean ") stderrorLabel = Tk.Button(root,text = "StdError: ") barGraph = Tk.Button(root,text = "Bar Graph ",fg = "red", padx=2,pady=2) lineGraph = Tk.Button(root,text = "Line Graph", fg = "red",padx=2,pady=2) pieGraph = Tk.Button(root,text = "Pie Graph ",fg = "red",padx=2,pady=2) titleEntry = Tk.Entry(root) xentry = Tk.Entry(root) yentry = Tk.Entry(root) nameXaxisEntry = Tk.Entry(root) nameYaxisEntry = Tk.Entry(root) meanText = Tk.Text(root,height=1,width=4) stderrText = Tk.Text(root,height=1,width=4) title_label.grid(row = 0, column = 0,sticky = Tk.E) xlabel.grid(row = 1, column = 0, sticky = Tk.E) ylabel.grid(row = 2, column = 0, sticky = Tk.E) nameXaxis.grid(row = 3, column = 0, sticky = Tk.E) nameYaxis.grid(row = 4, column = 0, sticky = Tk.E) barGraph.grid(row = 0,column = 1,ipadx=10,sticky=Tk.W) lineGraph.grid(row = 1,column = 1,ipadx=10,sticky=Tk.W) pieGraph.grid(row = 2,column = 1,ipadx=10,sticky=Tk.W) meanLabel.grid(row = 3,column = 1,ipadx=10,sticky=Tk.W) stderrorLabel.grid(row = 4,column = 1,ipadx=10,sticky=Tk.W) titleEntry.grid(row = 0, column = 0,ipadx=100,sticky=Tk.W) xentry.grid(row = 1, column = 0,ipadx=100,sticky=Tk.W) yentry.grid(row = 2, column = 0,ipadx=100,sticky=Tk.W) nameXaxisEntry.grid(row = 3, column = 0,ipadx=100,sticky=Tk.W) nameYaxisEntry.grid(row = 4, column = 0,ipadx=100,sticky=Tk.W) meanText.grid(row=3,column=3,sticky=Tk.W) stderrText.grid(row=4,column=3,sticky=Tk.W) # Adding line graph to Canvas-------------------------------------------- root.title("Naynts Graphs") #fig = Figure(figsize=(5,4), dpi=100) fig = plt.figure(figsize=(5,4), dpi=100) ax = fig.add_subplot(111) canvas = FigureCanvasTkAgg(fig,root) canvas.show() canvas.get_tk_widget().grid(row=7,column=0) toolbar_frame = Tk.Frame(root) toolbar_frame.grid(row=9,column=0) toolbar = NavigationToolbar2TkAgg(canvas, toolbar_frame) toolbar.update() #canvas._tkcanvas.grid(row=9,column=0) # Adding features to graph plt.xlabel('x label') plt.ylabel('y label') plt.title('Graph') plt.show() #root.mainloop() Tk.mainloop() 和from Tkinter import *。希望这有帮助！
