Bob,
Using the RE API you can get the chart model from a report design like:
import java.io.IOException;
import org.eclipse.birt.chart.model.Chart;
import org.eclipse.birt.chart.model.ChartWithAxes;
import org.eclipse.birt.chart.model.attribute.DataType;
import org.eclipse.birt.chart.model.attribute.SortOption;
import org.eclipse.birt.chart.model.component.Axis;
import org.eclipse.birt.chart.model.data.SeriesDefinition;
import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.model.api.DesignConfig;
import org.eclipse.birt.report.model.api.DesignEngine;
import org.eclipse.birt.report.model.api.DesignFileException;
import org.eclipse.birt.report.model.api.ExtendedItemHandle;

{
new GroupOnXSeries( ).groupSeries( );

cm.getTitle( ).getLabel( ).getCaption( ).setValue( "Group On X Series"

cm.getTitle( ).getLabel( ).getCaption( ).getFont().setSize(12);
cm.getTitle( ).getLabel( ).getCaption( ).getFont().setRotation(45);
SeriesDefinition sdX = (SeriesDefinition) ( (Axis) ( (ChartWithAxes) cm )
