Example: Data-Driven Lattice

About the Data-Driven Lattice Example

This example shows the sales for a line of retail products over a period of time. The custom graph object specifies a row-based lattice in which the rows correspond to the corporate divisions that are responsible for the sales. The corporation has two divisions, resulting in a graph with two rows.
