推荐答案
您需要从 NavigationToolbar2Tk
创建一个派生类来覆盖默认的水平方向.
You need to create a derived class from NavigationToolbar2Tk
to override the default horizontal orientation.
下面是一个示例(基于嵌入 Tk" 示例):
Below is an example (based on the "Embedding in Tk" example):
import tkinter as tk
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2Tk
from matplotlib.figure import Figure
import numpy as np
class VerticalNavigationToolbar2Tk(NavigationToolbar2Tk):
def __init__(self, canvas, window):
super().__init__(canvas, window, pack_toolbar=False)
# override _Button() to re-pack the toolbar button in vertical direction
def _Button(self, text, image_file, toggle, command):
b = super()._Button(text, image_file, toggle, command)
b.pack(side=tk.TOP) # re-pack button in vertical direction
return b
# override _Spacer() to create vertical separator
def _Spacer(self):
s = tk.Frame(self, width=26, relief=tk.RIDGE, bg="DarkGray", padx=2)
s.pack(side=tk.TOP, pady=5) # pack in vertical direction
return s
# disable showing mouse position in toolbar
def set_message(self, s):
pass
root = tk.Tk()
root.wm_title("Embedding in Tk")
fig = Figure(figsize=(5, 4), dpi=100)
t = np.arange(0, 3, .01)
fig.add_subplot().plot(t, 2 * np.sin(2 * np.pi * t))
canvas = FigureCanvasTkAgg(fig, master=root)
canvas.draw()
canvas.get_tk_widget().pack(side=tk.RIGHT, fill=tk.BOTH, expand=1)
toolbar = VerticalNavigationToolbar2Tk(canvas, root)
toolbar.update()
toolbar.pack(side=tk.LEFT, fill=tk.Y)
root.mainloop()
和输出:
