实时心电图实时散点图显示但混乱，如何清理？

如何解决实时心电图实时散点图显示但混乱，如何清理？

我有一些数据字典，我已经成功地使python实时更新并绘制。取得线路是可行的，但是现在我需要绘制散点图。我不确定如何设置实时更新数据，以便基本上可以相互绘制x2和y5，我习惯于将每个数据集分开，所以目前我有scatter2（x2）和scatter5（y5）分别更新，但是如何将它们像ax.scatter（x2，y5）而不是ax.scatter（x2）和另一行ax.scatter（y5）一起绘制？同时绘制它们，但分别绘制，使我得到了一个填充过度的散点图（也许它也保存了太多的值），并且似乎没有以与成功绘制的信号相同的速度移动。
