combining txt file and live data file

[kbernasc]

I have attached a picture of the problem I am having. I am trying to dump my live data into the txt file I have created with the proper headings. I can run the VI and the txt file is successfully made, but it does not contain the data collected from the appropriate graph. How do I allow the live data to combine with the txt file?

Thanks.

Hopefully this will help assist you.

Have you looked at the Write To Text File Example that ships with LabVIEW?

Wire up your data to a Write to Text and then post any additional questions you run into from there.

You need to get away from that Measurement File Express VI.  I highly recommend looking at the Array To Spreadsheet String function in the String Palette.  It will greatly reduce you code and make it a lot simpler.

As I said in your other thread, you need to use the File IO functions.  Open/create your file, then write the header data.  Use the Array To Spreadsheet String to make that a lot easier.  Then inside whatever loop you have, you can write your data as much as you want, using the same file reference.  Again, use the Array To Spreadsheet String to format your data and save it.  Then close the file when you are done.
