Discontinuous points in LineChart

[ekh]

Hi,

I am creating a LineChart with CartesianChartModel and ChatSeries. After digging here and there, by supplying a null value, the graph looks just as expected; when data actually doesn't exist for that particular time in the series.

Code: Select all

ChartSeries cs = new ChartSeries();
cs.setLabel("Some Label");
cs.set("June", 190);
cs.set("July", 200);
cs.set("August", 160);
cs.set("September", null);
cs.set("October", 220);
cs.set("November", null);
cs.set("December", 210);

The chart is beautifully drawn, however, when you mouseover the points, tips/tooltips get messed up for points after the first null. I've tried various combination of discontinuous points, and the issue keeps happening.

Thanks
