Need help averaging three waveforms without zeros

[TheLT]

Greetings,

  As part of a project I'm doing. I'm given a VI (attached) that has three waveforms. I need to average the three waveforms (generated with the ‘Introduce Zeros’ option ON - see the front panel) taking care not to include the zero values into the average. I then need to plot the resulting average with the original three waveforms.

   Now, I think I would need to do this with Interpolate 1D, but I'm not sure which method to use (spline, nearest, etc.) and, according to this VI attached, what gets wired to what. Now I did put 1D interpolate in there already, but when I do hit the Introduce Zeros Option, one of the waveforms disappears, so that's not right.

  Any help would be appreciated.

  Thanks!

Hi LT,

here's an idea:

Now you only have to include one more test in case all three waveforms show a zero for the same index...

GerdW,

   Thanks for posting back.

   OK, wait a minute, I was told that I don't need spline yet, just need to average the waveformsand being careful not to include the zero values in the average - and plot the resulting average with the original waveforms.

  I did try to implement your idea, but I don't think it does that. Can we please continue to discuss?

   Thanks!

Hi LT,

What do you want to discuss? My example does exactly (I hope) what you want! Atleast when I checked it with your data...

GerdW,

   I know wehre I went wrong. We're good. Thanks for your help.
