hi , in my project, on a K-Line chart, when i drag my mouse to choose an area, how can i recognize the data in this area?
I want to add event listener to the plot, but there is only one method: addChangeListener() . and in org.jfree.chart.event package, there are no class used to response the mouse movement.

thanks...........

I've found chartPanle class.....I think I've knew what to do...................
