从下面的代码中,我可以通过单击“replot”按钮来更新该行。我必须使用set_data()并绘制一个新的绘图,否则旧的绘图仍然在这里
但是,我希望程序自动更新animate()中的曲线,我使用5秒控件触发replot()函数,但失败了。如果我不使用blit=True,只使用blit=False,那么一切都很好。那么我的问题是如何更新由条件触发的动画中的曲线,并且还需要保持blit=True

不确定编程逻辑,但我认为可能至少有三个问题
first_replot最初设置为0,单击“collect”并经过5秒后,first_replot的值将始终为1。这意味着函数“animate”中不再有replot
函数“replot”最后一行的canvas.draw应为canvas.draw()
