How do you want the picture of your 3-dimensional array to look? If there's a picture from a book or article that you're trying to replicate can you post a link to that picture?
Open the Plots tab on the Toolstrip and click the downward pointing arrow on the right side of the Plots section of that tab. Look at the thumbnails until you find one that looks close to what you want. Open the documentation and search for the word under that thumbnail to see the syntax for the function that can create that picture.
