包含Tk嵌入的新答案（与其他答案相比有重大变化，因此添加新答案而不是编辑该答案）。我感动
graph_one()和
graph_two()进开关图包装类，并将其重命名为
draw_graph_one()和
draw_graph_two()。这两个新的类方法替换了
embed_graph_one()和
embed_graph_two()方法。
embed()方法中的大多数内容都是重复的，因此被移动到
config_window()实例化类对象时调用的方法。创建了一些类的数据成员捕捉PLT变量（例如
canvas，
ax，
fig），并创建了一个新的数据成员来跟踪其当前显示图（
graphIndex），以便我们能够正确得出正确的图形时
switch_graphs()被调用（而不是调用
embed_graph_two()每次进行“切换”（如原始代码一样）。（可选）您可以
t从
draw方法中取出并使其成为类数据成员（如果的值
t不变）。
