Increase Size of Dot in Graph

问题

I am creating a scatter plot graph using JFreeChart. Sometimes I only have a few points, and the dots are so small. They are almost invisible? Does anyone know how to increase the size of the dots?

Sorry if this seems trivial, I am new to JFreeChart.

Thanks

The OverlaidXYPlotDemoTZ class at this link: http://www.jfree.org/phpBB2/viewtopic.php?t=5068&highlight=xydotrenderer demonstrates how to do this.
