Click on Legend To Hide Series

Has anyone tried to hide a series by clicking on its legend entry?

I could only think of adding hide JCheckboxes on the chart's right click menu that toggled the visibility.

Is there a better way to do this?

I'm also looking for that functionality. Did you manage to do it?

You can add a ChartMouseListener to the ChartPanel and look out for LegendItemEntities. If you have the JFreeChart Developer Guide (and thus the demo source code), check out MouseListenerDemo3.java.

From there, you can hide a series either by physically removing it from the dataset, or setting the visibility flag in the renderer (not all renderers support this yet).

The problem with that is when you toggle a series' visibility, the legend's entry gets hidden too. How can you click on the entry to show the series again? I can only guess there is a setting to allow a series to be hidden without hiding the legend entries.
