Python 为什么当我在tkinter窗口内绘制3d图形时，它不允许我旋转图形或缩放

如何以交互方式旋转或缩放tkinter图形内的图形？它生成3D绘图，但之后它保持静态，我无法与它交互并旋转/更改视点的角度。 如果我在tk窗口外绘制它，它工作正常，似乎是在界面内绘制图形时出现的错误

绘图的功能是matplotlib文档中的lorenz吸引子

（python版本3.7.7）

如果需要更多的细节，请不要问我。谢谢

使用

tkinter

嵌入

matplotlib

图形时，应使用

matplotlib.figure.figure

而不是

plt.figure

。另外，

Figure

、

canvas

和

ax

的创建顺序也很重要：

def button_add():
    ...

    # Plot
    fig = Figure()

    canvas = FigureCanvasTkAgg(fig, w)
    canvas.draw()

    ax = fig.add_subplot(111, projection="3d")
    ax.plot(xs, ys, zs, lw=0.5)
    ax.set_xlabel("X Axis")
    ax.set_ylabel("Y Axis")
    ax.set_zlabel("Z Axis")
    ax.set_title("Lorenz Attractor")

    toolbar = NavigationToolbar2Tk(canvas, w)
    toolbar.update()

    canvas.get_tk_widget().pack(side=tkinter.TOP, fill=tkinter.BOTH, expand=1)

...

删除你之前的问题和我的评论，并再次发布完全相同的问题没有改变任何事情-这是不可复制的，因为没有窗口生成。可能是因为代码没有改变，而且是错误的。
