Changing custom colors in JFreeChart stacked 3D bar chart

Question

I have already searched enough on web but with no luck.

I have created a stacked 3d bar chart wherein I am unable to change the default colors. I tried all the advices provided .

Below a small snippet of my code. This is my input.

My Data from Db is:

A   0   2
B   15  53
C   0   2
D   0   2
E   0   1
F   1   0
G   0   1

Somehow I converted this to dataset requirement and also added items and models.

CategoryDataset dataset = DatasetUtilities.createCategoryDataset(item,models, data);
chart = ChartFactory.createStackedBarChart3D(chartDescription, X-axis, Y-axis, dataset,PlotOrientation.VERTICAL, true, true, true);
CategoryPlot plot = chart.getCategoryPlot();
CategoryItemRenderer r = plot.getRenderer();
r.setSeriesPaint(0, Color.GREEN);
r.setSeriesPaint(1, Color.GRAY);
 plot.setRenderer(new StackedBarRenderer3D() {

@Override
public Paint getItemPaint(int row, int col) {
    System.out.println("row:"+row);
    System.out.println("Col:"+col);
    return Color.getHSBColor(row / 42f, 1, 1);
}
});
CategoryAxis domainAxis = plot.getDomainAxis(); 
domainAxis.setCategoryLabelPositions(CategoryLabelPositions.UP_90);

NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
rangeAxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());

StackedBarRenderer3D renderer = (StackedBarRenderer3D)plot.getRenderer();
//renderer.setBarPainter(new StandardBarPainter());
renderer.setSeriesFillPaint(0,Color.BLACK);
renderer.setSeriesFillPaint(1,Color.GREEN);
renderer.setDrawBarOutline(false);
renderer.setShadowVisible(false);
renderer.setBasePositiveItemLabelPosition(new ItemLabelPosition(ItemLabelAnchor.CENTER,TextAnchor.CENTER));
renderer.setBaseItemLabelGenerator(new StandardCategoryItemLabelGenerator());
renderer.setIgnoreZeroValues(true);
renderer.setMaximumBarWidth(.05);
renderer.setBaseItemLabelsVisible(true);
renderer.setBaseToolTipGenerator(new StandardCategoryToolTipGenerator());
renderer.setPositiveItemLabelPositionFallback(new ItemLabelPosition(
    ItemLabelAnchor.CENTER, TextAnchor.CENTER_RIGHT));
renderer.setNegativeItemLabelPositionFallback(new ItemLabelPosition(
ItemLabelAnchor.CENTER, TextAnchor.CENTER_RIGHT));
renderer.setBasePositiveItemLabelPosition(new ItemLabelPosition(
    ItemLabelAnchor.CENTER, TextAnchor.TOP_CENTER));
renderer.setBaseNegativeItemLabelPosition(new ItemLabelPosition(
    ItemLabelAnchor.CENTER, TextAnchor.TOP_CENTER));
LegendTitle legend = chart.getLegend(0); 
legend.setBackgroundPaint(Color.white);
legend.setFrame(new BlockBorder(Color.green));
StandardChartTheme theme = (StandardChartTheme)org.jfree.chart.StandardChartTheme.createJFreeTheme();
theme.setTitlePaint(Color.decode("#4572a7"));
theme.setExtraLargeFont(new Font("Arial",Font.BOLD, 16) ); 
theme.setLargeFont(new Font("Arial",Font.BOLD, 15)); 
theme.setRegularFont( new Font("Arial",Font.PLAIN, 11));
theme.setRangeGridlinePaint(Color.RED);
theme.setPlotBackgroundPaint( Color.white );
theme.setChartBackgroundPaint( Color.white );
theme.setItemLabelPaint(Color.YELLOW);
theme.setShadowVisible(true);
theme.setAxisLabelPaint( Color.decode("#666666")    );
theme.apply( chart );

EvenI have used setSeriespaint, but it is not working. Is there anything to do with the order of creation in chart,plot and renderer?

When I print the row and column I get this:

row:1
Col:0
row:0
Col:1
row:1
Col:1
row:1
Col:2
row:1
Col:3
row:1
Col:4
row:0
Col:5
row:1
Col:6

You can override the renderer's getItemPaint(), as shown here.

plot.setRenderer(new StackedBarRenderer3D() {

    @Override
    public Paint getItemPaint(int row, int col) {
        return Color.getHSBColor(row / 42f, 1, 1);
    }
});
