在 Tkinter 中移动正弦波

Question

我需要知道如何使用 Tkinter 在屏幕上看到移动的正弦波 我已经用 pygame 做到了，但我认为用 Tkinter 做到这一点很复杂。 我认为我需要做的第一件事是定义一个绘制正弦波的函数，然后定义其他函数来为这个绘制提供运动。那是对的吗？还是我想错了？如何在屏幕上移动正弦波？

我从 matplotlib.org 中提取的代码是：

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation

fig, ax = plt.subplots()

x = np.arange(0, 2*np.pi, 0.01)        # x-array
line, = ax.plot(x, np.sin(x))

def animate(i):
    line.set_ydata(np.sin(x+i/10.0))  # update the data
    return line,

#Init only required for blitting to give a clean slate.
def init():
    line.set_ydata(np.ma.array(x, mask=True))
    return line,

ani = animation.FuncAnimation(fig, animate, np.arange(1, 200), init_func=init, interval=25, blit=True)
plt.show()

Answer 1

我不理解“移动”，但很可能会使用 matplotlib。

import matplotlib.pyplot as plt

fig = plt.figure(frameon=False)
ax = fig.add_axes([0, 0, 1, 1])
ax.axis('off')

ax.plot(range(10))
plt.show()

Answer 2

在许多其他帖子的帮助下，我终于移动了七个正弦波。这是最终结果：
