Exporting selected channels to a text file

[zezendapuss]

Hello,

I am acquiring analog data from 8 channels and storing them in a text file.

This program stores all the 8 channels as columns in the text file.

However i would like to choose with a user input ( something like a plot visibility checkbox) and store selected channel in the text file.

I have tried index array, subarray but have failed to come up with a solution.

Any pointers/solution would be appreciated.

Hi zezendapuss,

I have tried index array, subarray but have failed to come up with a solution.

Use an array of 8 booleans to switch on/off saving of your data channels.

Then select the data columns based on boolean state.

It all boils down to use either autoindexing loops or IndexArray/ArraySubset - both are basic LabVIEW elements/functions. Did you take the free online courses to learn LabVIEW?

General hint: When there is a problem in your VI you should attach that VI so we can inspect it…
