Python I´；我是Tkinterer的新手，有谁能帮我制作一个基于矩阵的2d图形吗？

我在网上什么都试过了，但都没用。我只想要一个2d图，它表示一个矩阵的结果。假设我的代码的这一部分是矩阵计算器，我现在很难在给出结果后弹出一个显示图形的屏幕。顺便说一句，我没有错过任何图书馆

 def inversa():
        a11=float(k1.get()) #saves user imput
        a12=float(k2.get())
        b21=float(k4.get())
        b22=float(k5.get())
        R1=[]
        R2=[]
        R1.append(a11)
        R1.append(a12)
        R2.append(b21)
        R2.append(b22)
        A =[R1,R2]
        A = np.matrix(A)
        mat2=np.linalg.inv(A)
        tkinter.messagebox.showinfo("The inverse matrix is : ","%s"%mat2)

我建议调查一下。您可以使用matplotlib首先打印图形，然后将其放置到tkinter窗口中

要将matplotlib图形集成到tkinter中，可以使用matplotlib的后端类FigureCanvasTkAgg

要导入它-：

from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg

然后可以使用figure对象将打印的图形放置在图形画布上，如所示：

fig = Figure(...) # Initializing the figure object.
canvas = FigureCanvasTkAgg(fig, master=root) # Initializing the FigureCanvasTkAgg Class Object.
tk_canvas = canvas.get_tk_widget() # Getting the Figure canvas as a tkinter widget.
tk_canvas.pack() # Packing it into it's master window.
canvas.draw() # Drawing the canvas onto the screen.

此外，还可以使用matplotlib方法绘制地物对象

所以完整的代码变成-：

from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg

fig = Figure(...) # Initializing the figure object.
canvas = FigureCanvasTkAgg(fig, master=root) # Initializing the FigureCanvasTkAgg Class Object.
tk_canvas = canvas.get_tk_widget() # Getting the Figure canvas as a tkinter widget.
tk_canvas.pack() # Packing it into it's master window.
canvas.draw() # Drawing the canvas onto the screen.
