Waveform chart goes crazy

[soljiang]

For some reason I'm just showing the data of arrays on waveform chart but the chart goes crazy even if I don't show any plot.   When the input is nothing but a single sine wave, the picture underneath shows the craziess how the chart looks.  Could anybody tell me why it happens and how to solve the problem?

Thank you very much!

Best,

Charles

Oh, sorry, never mind. I think I solved the problem.  Anyway to delete a post?

Instead of deleting this thread, you could post the solution you came up with incase others have similar problems.

I figured that the problem actually lies in the sampling, not the chart per se.
