<%// FillAreas:%>

<%
// When the specification on the data model generates multiple plot lines,
// the areas between the lines can be filled by calling the
// LineChartModel's setFillAreaEnabled() method with the argument value
// true. Optionally, you can define a fill for the areas and set the
// fill on the DataElementStyles. This sample uses the SubgroupVariable
// role to generate multiple plot lines.
