How can I save 3 of 1D arrays into excel file neatly? VI file is attached. Thanks...

[Baho]

I have 3 of the 1D arrays. When I combine them, I get 1 very long column in excel. Instead I want to have three columns of shorter arrays. I attached the vi. Besides, is there any way I can write on the 1st row of the same excel file.

There's more than one way to "combine" arrays.

Look at the BUILD ARRAY function.

If you wire three arrays to three inputs, you have a choice of outputs:
You can CONCATENATE the inputs, in which case the output is a longer 1-D array.

If you DON'T concatenate them, the output is a 2-D array, which sounds like what you want.

You will probably want to TRANSPOSE the 2-D ARRAY, as this will give you three columns of N rows. Without transposing, you get three rows of N columns.

If the original arrays are not equal length, they will be padded with zeroes.
