Series break in a line chart

Is there a way I can make a series break in a line chart (not connect the data points at certain times) ... Passing in Double.NaN causes Java2D problems.

Thanks

You simply add a data point that has the x value of the point you want to skip and null for the missing y value. In the plot, points with null values will show up as gaps in the plot.

Hi Daniel,

As you said values as null would be shown as balnk in line graph,
But in my case i want to show gap when data is not collected( ie not stored in database ) for certain period. so there would be no data in database in this particular period and i need to show it as blank.

Thanks

Let me clarify what I said. When there is a domain value (usually horizontal axis) but no range value (usually vertical) axis in a XYPlot, then JFreeChart will render a gap in the line.

If you do no have data for a particular period, you will know the domain value. Just use null as the range value for those cases.
