我知道这个心不是在做的事情，因为我相当新的蟒蛇，但请与我裸露，我有一个GUI，我使用从发送一个查询数据的最Python的方式一个arduino。然后，我开始实时绘制这些数据而不减速。我目前正在逐渐与更多的数字，我正在策划减缓和我有类似的问题，当我第一次在MATLAB写了这个GUI。我想知道，如果我最终希望能够一次绘制多个窗口，那么我是否可以做得更快。我知道从以前的建议，动画库，但是未成功，得到它的工作从我的Tkinter对象的insife我了解，这将是加快除了直画到画布上绘图的理想方式。我只需要一次绘制大约200点的数据。这是当前GUI代码：如何加快Tkinter的嵌入式matplot lib和蟒蛇
