How to input different files in a loop

[etedwin]

Hello!

Currently, my VI plots out result based on my measurement which comes in the form of a csv file. The picture i attached reads the csv file into a subVI to generate the result. As i would like to plot the result of multiple csv files, what i can get this objective going is to read individual csv file into individual similiar subVI and combine to get the result.

Therefore, I would like to have multiple csv files generated into a loop with a single subVI to process my measurement, how do i go about creating the loop and reading the different files?

Hi etedwin,

you seem to read just one row from each file…

- I would put those rows into an array (when they have different length  I would use an array of cluster of array).

- Then I would call this subVI with the array containing all rows and additionally a parameter describing which rows to use for calculations…

<sarcasm> You don't like to use AutoCleanup before uploading images of your VI? You understand LabVIEW code much better with hidden and bended wires all over?</sarcasm>

Sounds like a simple FOR loop to me.  Just put your files into a array and autoindex on that array.  You can also autoindex the output to create the output arrays as well.

 Hi crossrulz,

which are the files are you referring for me to put into an array?

Create an array of filenames and autoindex that array on a FOR loop that operates on one file per iteration.

Hi altenbach,

I think i have gotten it. I have my results in! Attached the picture as shown

That code makes absolutely no sense! Everything belongs into one loop. Your blue-green code in the upper left is not even used, delete it! You don't have an array of file names as suggested. It makes no sense to create a 3D array. Do all files have arrays of the same dimension? Are you really trying to read zero rows?

Please attach your VI instead of pictures. Also include a few datafiles.
