This is my sample code to to show jfreechart tooltip on the image.
The key is to override onComponentTagBody() and use replaceComponentTagBody().
Just post my tried to share.
There should be better way to tune the performance.
--source code here--
public class JFreeChartImage extends NonCaching
.getImageMap(imageMapId, info));
}
public JFreeChart getChart() {
return chart;
}
public void setChart(JFreeChart chart) {
this.chart = chart;
}
}
