I got a very strange problem with my waveform chart display, it can only display 2 plots on one waveform chart. I need to display 4 plots on one waveform chart at the same time, please give me some good ideas how to do this. The waveform chart reference is used. My program has been attached, please run it to see the problem, only zeros are displayed, if you only connect two data, the display is correct (you need to change subvi). LabVIEW8.5 is required.
