在Tkinter中移动正弦波

我需要知道如何在屏幕上看到使用Tkinter移动的正弦波 我已经用pygame做了这件事，但我认为使用Tkinter做起来很复杂。我认为我需要做的第一件事就是定义一个函数，它绘制正弦波，然后定义其他函数，以便为此绘制运动。那是对的吗？还是我想错了？如何在屏幕上移动正弦波？在Tkinter中移动正弦波

，我提取matplotlib.org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()

我不明白“移动”，但matplotlib也最有可能被使用。

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()

我已经做matplotlib现在我想用Tkinter的为ANIMATE正弦波 –

我不明白这一点。但是你可以生成一张图片列表，并在Tkinter中连续显示。但matplotlib解决方案有什么问题？ –

因为我需要绘制多个正弦波（七个）。我不能有任何轴或按钮，我也必须将窗口的大小更改为全屏。我只能看到正弦波，没有更多。 –

我终于在许多其他帖子的帮助下移动了七个正弦波。这是最终的结果：
