I did a webinar on the DE-API
http://www.birt-exchange.com/be/news-events/resources/?artic leid=17456
Take a look at these examples from the webinar:
http://www.birt-exchange.org/devshare/designing-birt-reports /409-deapi-examples-from-birt-exchange-webinar/#description
I also did one on the chart api:
http://www.birt-exchange.com/be/info/chartingapi-websem/
You may want to look over the list:
http://www.birt-exchange.com/be/news-events/webinars/archive d-webinars/
There are also plenty of examples in the dev share at birt-exchange
Attached is a simple example that creates a chart:

Carl,
If would be good if you could add your example to Birt-Exchange.com dev
share.

Bob,
You can set properties directly
data = elementFactory.newDataItem( null );
data.setProperty( StyleHandle.FONT_FAMILY_PROP,"Arial");
or modify the default report style property
reportDesignHandle.findStyle("report").setProperty(StyleHandle.FONT_FAMILY_PROP,
"Arial");
or use a new style. To create a style use the ElementFactory like:
private void createStyles( ) throws SemanticException
{
StyleHandle labelStyle = elementFactory.newStyle( "Label" );
labelStyle.setProperty( StyleHandle.FONT_WEIGHT_PROP,
DesignChoiceConstants.FONT_WEIGHT_BOLD );
labelStyle.setProperty( StyleHandle.FONT_FAMILY_PROP, "Arial Black" );
labelStyle.setProperty( StyleHandle.COLOR_PROP, "#008000" );
StyleHandle dataStyle = elementFactory.newStyle( "Data" );
dataStyle.setProperty( StyleHandle.FONT_WEIGHT_PROP,
DesignChoiceConstants.FONT_WEIGHT_BOLD );
dataStyle.setProperty( StyleHandle.FONT_FAMILY_PROP, "Century"
);//$NON-NLS-1$
dataStyle.setProperty( StyleHandle.COLOR_PROP, "#009B9B" );
reportDesignHandle.getStyles( ).add( labelStyle );
reportDesignHandle.getStyles( ).add( dataStyle );
}
Then set the style on an element like:
CellHandle tcell = (CellHandle) header.getCells( ).get( 0 );
LabelHandle label = elementFactory.newLabel( null );
label.setText( "Product" );
label.setStyleName( "Label" );
tcell.getContent( ).add( label );
