在上面的程序中,realTimePlot()函数用来实时绘制正弦曲线,每次调用绘制一条新的曲线,并通过drawnow函数将图形显示出来,然后暂停0.1秒等待下一次调用。startBtnCallback()函数用来创建一个Timer对象,定期调用realTimePlot()函数实现实时绘图,而stopBtnCallback()函数用来停止Timer对象的运行。

If it gets too slow please consider the preallocation of XData and YData, fill it with NaN values and when the loop gets to the end of the preallocated data do something to "reset" it, if your script only runs for a short while you don't have to do it.
