There are two ways to do it. You can bundle an array of X values with the array of Y values and then build an array of such clusters, OR you can bundle the X and Y values so that you have an array of XY clusters and bundle the whole array to get a cluster with that array and then build an array of the different clusters(puh...)
You can find an example if you search for XY in the find example function; the XY graph.vi
