How to customize a tooltip of CategoryPlot items in JFreeChart?

I need to change the format of the default tooltip in the bars drawn in the plot of a chart.

I don't know if my direction of looking at the problem is right. I am looking at the default format for the class StandardCategoryToolTipGenerator that is 

DEFAULT_TOOL_TIP_FORMAT_STRING = "({0}, {1}) = {2}"

How can I redefine this value?

Thanks in advance.

The StandardCategoryToolTipGenerator sets the MessageFormat ArgumentIndex values to the series, category and value. Try this example on your plot.

BarRenderer renderer = (BarRenderer) plot.getRenderer();
renderer.setBaseToolTipGenerator(new StandardCategoryToolTipGenerator(
    "Series {0}, Category {1}, Value {2}", NumberFormat.getInstance()));
