Are you using the chart library as standalone. Or is it a chart in a BIRT
report?

Thanks,

David

Please take a look at the org.eclipse.birt.chart.examples plugin. There are
many standalone examples and you can see there how to set the size of the
chart, instead of using the default one.

Thanks,

David
