Floating Bar/Gantt with multiple images / icons on top

[javapda]

I would like to create a chart where each row is represented by a horizontal bar. And on the bar there are some decorations (Icons/Letters/Shapes).

The tooltips and generated Image Map need to present information for both the background bar and the individual decorations.

Below is a mock-up of the chart. It has as input a time period (range/interval) and a number of discrete dates. Each discrete date is presented as a decoration.

I have been able to create a subclass of GanttRenderer to produce the bar and a single icon/decoration but the output information (tooltip and url for image map) is general for the entire bar.

Thanks in advance.

I had the same problem (with JFreeChart 1.0.0-pre2). To solve this I created a subclass of IntervalCategoryToolTipGenerator and modified the drawTasks method in GanttRenderer class.

I have posted a feature request with the code :
