I am ploting XY Series plots in a JSp page ,Now i am able to use the tool tip feature of
JFreeChart.Now i want to highlight all the data points of a series once any of the points of the series is clicked

How to do this can any one suggest ?

There is no way to do this automatically, the chart does not supply this exact functionality by default.

The only way to do this is to identify the x, y values from the mouse event and manually draw a XYShapeAnnotation as a circle (or another shape) around each point you want to highlight. This of course means you have to save each point you want highlighted yourself and draw a new XYShapeAnnotation for each one.

...just re-read your post. Just in case you mean that you want to change every single point in a series once you select only one of them, the easiest way to accomplish this is to reset the parameters of the actual series renderer such as:

renderer.setSeriesShape
renderer.setSeriesPaint
