I don't have any link but you may show your boss the demo-jar that comes with the APIs. Show your boss tooltip labels of PieChartDemo2.java and pieChart2DDemo1.java, (remove the aplpha, for making solid colors) if properties of these two charts are combined, which can be, you will get what your boss wants. colors of the tooltip background is also configurable and also can customize the tooltip data format. Following explanation will help you in customizing the labels for tooltip. This is taken from the Jfree Developer guide 1.0.4.

The StandardPieSectionLabelGenerator class is typically used as the generator, and provides enough flexibility to handle most custom labelling requirements (but if not, you are free two write your own class that implements the PieSectionLabelGenerator interface). The generator works by using Java’s MessageFormat class to construct labels by substituting values that are derived from the dataset:

Key --> Value:
{0} --> The section key as a String.
{1} --> The section value.
{2} --> The section value as a percentage of the total of all values in the dataset.

By way of example, suppose you have a PieDataset containing the following values:
Section Key --> Section Value:
S1 --> 3.0
S2 --> 5.0
S3 --> null
S4 --> 2.0

following format strings would generate the labels shown:
Format String --> Section --> Generated Label:
{0} --> 0 --> S1
{0} has value {1} --> 1 --> S2 has value 5.0
{0} ({2} percent) --> 0 --> S1 (30 percent)
{0} = {1} --> 2 --> S3 = null

I don't know about applying gradient on tooltips. Lets wait what GURU has to say about it.

Hi,

I have just found an
pieplot.setLabelBackgroundPaint(new GradientPaint(0.0F, 0.0F, Color.white, 1000F, 0.0F, Color.red));

that make an gradiant color on all label, but for example i want that each label in PiechartDemo2 as same color like section ?
I search too an gradiant and 3d effect on theses labels
