LabVIEW Arrays • An array is a collection of data elements. The data

elements in an array can be numeric, Boolean, string or cluster, but all data elements must be of the same type within an array. Arrays can be one or two-dimensional

• One Dimensional Arrays have elements and indices. Below is a 7-element, one-dimensional array. Notice that the first element has index 0, the second element has index 1, etc.

LabVIEW Arrays• Creating a Two Dimensional Array

You create a two-dimensional array by modifying a one-dimensional array. Pop up on the index display > Add Dimension. Then re-size the array display vertically to display the columns.
