How to show the tooltip for jfreecharts rendered as images on jsp

Question

I am using JFreeChart, and I am rendering the chart as an image using a servlet via JSP. I saw the tooltips while using a chart frame. How can I display tooltips on the JFreeChart image. Please help me; it's important.

Answer 1

In a servlet/JSP environment, the dynamic features of a chart are unavailable. For tooltips, you can achieve a similar effect using a label generator, shown here . Of course you can supply any desired request parameters to the servlet, at the expense of re-generating the chart with each new request.

For an improved user experience, consider deploying your chart using Java Web Start , in addition to offering the static image via JSP. This related example may suggest the basic possibilities.
