Adding tooltips to a chart (JFreeCharts)

Issue:

Requirement: need to add a tooltip to a chart. For example, you have a Pie chart and need each category to display category value in a tooltip when hevering mouse over this category.

Resolution:

It is possible to define tooltips using hyperlink options without actually specifying hyperlink.

It can be done by specifying Section hyperlink for Pie chart in Chart Details window->Details->Pie series. Set hyperlink target to "Self" and hyperlink type to "none".

This works in the Internal Preview and HTML Preview in iReport. The report source is the "Foodmart" database that ships with the product.
