How to enable tooltip if not use ChartFactory?

[rspan]

If not use ChartFactory to create JFreeChart object, just use JFreeChart constructor, is there any way to enable tooltip?

Thanks.

Yes. You will need to get the Plot object from the JFreeChart object, get the renderer(s) from the plot, and set the appropriate tool-tip generator. You can use the javadoc starting from JFreeChart and work your way though.
