How to show all the data from playback area so that the statictics max and min analysis applies to the entire logged data.

[THurst]

I have a data file with 19 channels of voltage and I what to retrieve the maximum, minimum and mean of the entire run for each channel. When I do playback it does only 25 seconds of data and being a newbie I have no idea nor can see anyway of changing this.

One thought I had was to run playback with a save to LVM then go to mointor area and load the saved file followed by a statictics step.

Is there any other option?

We need more information to help you.  Specifically, the following would be nice:

1. What format is your data file in (can you post an example?  Please zip it to save space.)
2. Can you post your read and/or write code?  The problem may be there.
3. What version of LabVIEW are you using.  This can effect our recommendations.
   

As you discerned, there is no fundamental reason for this problem.  On a side note, LVM is a poor format for large amounts of data or a disk buffer.  I would recommend TMDS or HWS, depending on your version of LabVIEW.

Actually I have figured it out. This was a SignalExpress issue. I was able to change playback settings to view entire data.

Hi THurst,

I'm glad that you found a solution to your problem, but would you mind sharing what settings you needed to change to make things work. Pressing Run in playback mode should send the log to the statistic step and retain the values that you are looking for, while playing back the entire set of data. We think you are logging the 19 channels of data in monitor mode and then using a Statistics step in playback.  Is this correct?

Perhaps you wouldn't mind attaching your project so we can get a better look at what you are doing?

Thanks for any information you could provide.
