We’ll need more than one because while certain attributes (e.g., chart title) can be set programmatically, others, including type (e.g., column or line), must be hard-coded into the chart object.

Today we’re going to look at applying the virtual list technique to FileMaker charting with the goal of producing a reusable chart “object”, or rather, a series of chart objects.
