从文本文件里读取数据

[xiao shao]

我在做一个环境检测的project,就是对于已经储存到文本文件里的数据进行分析。要求是把数据显示到waveform chart里，并且数据要一个一个连续的display出来。目前我只可以把所有的数据一次全显示出来，请问各位高手，怎样加个loop可以控制数据依次出现？

Actually, i dont known what is this "basic function generator".and how it works.

In this case, I am using it merely for generating the sine waveform for demo purpose...
