1d array double into multicolumn listbox

[tman2013]

I have been trying for the last day now to get this 1D array of double into my multicolumn list box. 

Each time I want the row to represent the data I just collected.   I figure I need a for loop in here somewhere, but I am just trying to get the data to come into the columns first.  

Can someone tell me how to get my 1D array of double into the multicolumn list box?      I have read lots of posts, but none have worked so far.   I need to convert to string first I think. 

Here is a clip of the code

Thanks for your help

Wire the DBL array into a Number to Fractional String primitive. It will convert it to a 1D array of strings which you can now wire into the Build Array primitive.
