Choose waveform to display

[MogaRaghu]

I am saving an array of analog channels as waveform data during the running of a test rig at frequent intervals of say once every 15 minutes. The data captured will be for about 10seconds.

Each of these waveform arrays have the data pertaining to 7 different parameters.

The user will later select a particular data thus saved and view it. The issue however is,  he may select any number of channels out of the seven and view them at the same time. He will thus need the facility of multiple Y-Scales that are relevant to the choosen channels for display.

I was studying one of the examples that comes with LV and wanted develop the idea from there. The selected VI is attached where I tried to display two channels at a time. Though it compiled , the second waveform was not to be seen.

What  is happening ?

Thanks

Hi,

You do not have anything wired into the input of the second WDT Index Channel DBL.vi.

Wire the array of waveforms that you created into the input of the second WDT Index Channel DBL.vi - this should work.
