<%// SetBaseline:%>

<%
// The BarChartModel class lets you set a reference line that
// serves as a base line for the bar chart. Response values greater
// than the baseline value are displayed as bars above the baseline, 
// and response values below the baseline value are displayed as
// bars below the baseline value. To set the baseline, call the
// BarChartModel's setResponseAxisBaselineModel() method.
