Hi David,
How do you want the missing values to be handled? In JFreeChart, we use null to represent a missing or unknown value - this usually results in a gap being displayed (which may or may not be different to a zero, depending on the chart type). Are you looking for a feature that displays some kind of marker to indicate that there is a missing value? It wouldn't be hard to modify JFreeChart to do that...
Regards,
Dave Gilbert
