tkinter在用画布指定位置内嵌动态变化曲线代码

以下是一个使用Tkinter画布(canvas)嵌入动态变化曲线的示例代码：

import tkinter as tk
import math

class Graph:
    def __init__(self, canvas, x_min, x_max, y_min, y_max, func):
        self.canvas = canvas
        self.x_min = x_min
        self.x_max = x_max
        self.y_min = y_min
        self.y_max = y_max
        self.func = func
        self.draw_axes()

    def draw_axes(self):
        # 画坐标轴
        width = self.canvas.winfo_width()
        height = self.canvas.winfo_height()
        self.canvas.create_line(0, height/2, width, height/2, fill="black")
        self.canvas.create_line(width/2, 0, width/2, height, fill="black")

    def draw_graph(self):
        # 画函数图像
        width = self.canvas.winfo_width()
        height = self.canvas.winfo_height()

        x_range = self.x_max - self.x_min
        y_range = self.y_max - self.y_min

        points = []
        for i in range(-width//2, width//2):
            x = i / (width//2) * x_range + (self.x_max + self.x_min) / 2
            y = -self.func(x)
            j = (y - self.y_min) / y_range * height
            points.append(i + width//2)
            points.append(j)

        self.canvas.delete("graph")
        self.canvas.create_line(points, tags="graph", fill="red")

class App:
    def __init__(self, master):
        self.master = master
        self.canvas = tk.Canvas(master, width=400, height=400)
        self.canvas.pack()

        self.graph = Graph(self.canvas, -10, 10, -10, 10, math.sin)
        self.animate()

    def animate(self):
        self.graph.draw_graph()
        self.master.after(10, self.animate)

root = tk.Tk()
app = App(root)
root.mainloop()

在这个例子中，我们定义了一个Graph类来画曲线，它包含了画坐标轴和画函数图像的函数。我们在App类中创建了一个Graph实例，并使用`after`函数来实现动态更新。这个例子中的函数是sin函数，你可以替换成你自己的函数。
