JFreeChart Dual Axis Problem

Question

Hi:
I've developed a Dual Axis Chart (bar and line char) using the JFreeChart library.
However, when the chart is displayed in the screen the line chart appears always behind the bar chart. How can I solve this? I would like that the bar chart appears behind the line chart.
Here you can find a little bit of code:
           final DefaultCategoryDataset dataset = new DefaultCategoryDataset();
           final DefaultCategoryDataset dataset2 = new DefaultCategoryDataset();
// Here I add values to the datasets
            JFreeChart chart;
            if(tres.isSelected()) chart = ChartFactory.createBarChart3D("EVOLUCI� DE LA PRODUCCI� DE RESIDUS MUNICIPALS ("+c+") "+dd1+" --> "+dd2+". QUANTITATS EXPRESADES EN KG. / HAB. * DIA", "MES", "KG. / HAB. * DIA", dataset, PlotOrientation.VERTICAL, true, true, false);
            else chart = ChartFactory.createBarChart("EVOLUCI� DE LA PRODUCCI� DE RESIDUS MUNICIPALS ("+c+") "+dd1+" --> "+dd2+". QUANTITATS EXPRESADES EN KG. / HAB. * DIA", "MES", "KG. / HAB. * DIA", dataset, PlotOrientation.VERTICAL, true, true, false);
            chart.setBackgroundPaint(new Color(204, 204, 255));
            final CategoryPlot plot = chart.getCategoryPlot();
            plot.setBackgroundPaint(Color.white);
            plot.setDomainAxisLocation(AxisLocation.BOTTOM_OR_LEFT);
            plot.setRangeAxisLocation(AxisLocation.TOP_OR_LEFT);
            final CategoryItemRenderer renderer1 = plot.getRenderer();
            renderer1.setSeriesPaint(0, Color.RED);
            final ValueAxis axis2 = new NumberAxis3D("POBLACI�");
            plot.setRangeAxis(1, axis2);
            plot.setDataset(1, dataset2);
            plot.mapDatasetToRangeAxis(1, 1);
            final CategoryItemRenderer renderer2 = new LineAndShapeRenderer();
            renderer2.setSeriesPaint(0, Color.blue);
            plot.setRenderer(1, renderer2);
            plot.setDatasetRenderingOrder(DatasetRenderingOrder.REVERSE);
            plot.setNoDataMessage("NO HI HA DADES");
            ChartFrame frame = new ChartFrame("COMPOSICI� DELS RESIDUS MUNICIPALS", chart);
            frame.setIconImage(new ImageIcon(getClass().getResource("/rsu/Imatges/reciclatge.gif")).getImage());
            frame.pack();
            Dimension dPan = Toolkit.getDefaultToolkit().getScreenSize();
            Dimension dFin = frame.getSize();
            Double x = new Double((dPan.getWidth()-dFin.getWidth())/2);
            Double y = new Double((dPan.height - dFin.height)/2);
            frame.setLocation(x.intValue(), y.intValue());
            frame.setVisible(true);Lots of thanks for your help.

Hi, I'm new using Java and JFreeChart and I'm facing a problem. I need to draw a XY chart with 2 series and assign each one a choosen color, but I can only have them in the same color! I don't know what I'm doing wrong. Can anybody help me whit this?
Thanks in advance,
Freddy
P.D: This is the code for what I'm trying to do (excuse my english)
final TickUnits units = new TickUnits();
               units.add(new NumberTickUnit(337.5, new CompassFormat()));
               units.add(new NumberTickUnit(315.0, new CompassFormat()));
               units.add(new NumberTickUnit(292.5, new CompassFormat()));
               units.add(new NumberTickUnit(270.0, new CompassFormat()));
               units.add(new NumberTickUnit(247.5, new CompassFormat()));
               units.add(new NumberTickUnit(225.0, new CompassFormat()));
               units.add(new NumberTickUnit(202.5, new CompassFormat()));
               units.add(new NumberTickUnit(180.0, new CompassFormat()));
               units.add(new NumberTickUnit(157.5, new CompassFormat()));
               units.add(new NumberTickUnit(135.0, new CompassFormat()));
               units.add(new NumberTickUnit(112.5, new CompassFormat()));
               units.add(new NumberTickUnit(90.0, new CompassFormat()));
               units.add(new NumberTickUnit(67.5, new CompassFormat()));
               units.add(new NumberTickUnit(45.0, new CompassFormat()));
               units.add(new NumberTickUnit(22.5, new CompassFormat()));
               XYDataset dataset7 = createhourDataset(24,50,"Velocidad");
               JFreeChart chart8 = ChartFactory.createTimeSeriesChart("Diaria", "Hora", "mps", dataset7, true, true, false);
               XYPlot plot2wd1 = chart8.getXYPlot();
               final XYItemRenderer r1 = plot2wd1.getRenderer();
               r1.setSeriesPaint(0, Color.RED);
               ValueAxis axis2wd1 = new NumberAxis("");
               axis2wd1.setRange(0.0, 360.0);
               plot2wd1.setRangeAxis(1, axis2wd1);
               axis2wd1.setStandardTickUnits(units);
               axis2wd1.setAxisLinePaint(Color.blue);
               axis2wd1.setTickLabelPaint(Color.blue);
               axis2wd1.setTickMarkPaint(Color.blue);
               plot2wd1.setDataset(1, createhourDataset(24,50,"Direcci�n"));
               final XYItemRenderer r2 = plot2wd1.getRenderer();
               r2.setSeriesPaint(0, Color.blue);
               plot2wd1.setRenderer(1, r2);
               ChartPanel panel_D1 = new ChartPanel(chart8);
