How to add two lines with different renderers in JFreeChart?

[Srilatha]

Hi ,
Can u suggest me how to go about the problem?
I want to plot two different lines with different renderer types into single JFree chart.One line i want to plot as without default shapes.and the other line, I want to plot as with default shapes.
Pls. make a note that is I need to get x-axis length as 100%.
Here, I have added the code which i have written:
Please take a look at this code and suggest me how to go about this further:

Alternately if you could use category plot i know the solution.

Hi,

I have this code:

Code: Select all

ChartPostProcessor cpp = new ChartPostProcessor() {

    public void processChart(Object chart, Map params) {
        final JFreeChart chart1 = (JFreeChart)chart;
        final CategoryPlot plot = chart1.getCategoryPlot();

        plot.setBackgroundPaint(Color.white);
        //display domain labels vertically
        plot.getDomainAxis().setCategoryLabelPositions(plot.getDomainAxis().getCategoryLabelPositions().UP_90);

        plot.setRenderer(new LineAndShapeRenderer() {
            public Paint getItemPaint(int row, int item) {
                double y = plot.getDataset().getValue(row, item).doubleValue();
                if ((y >= usl)||(y <= lsl) || (y >= ucl) || (y <= lcl)) {
                    return Color.RED;
                }
                return Color.BLUE;

            }

            public Shape getItemShape(int row, int item) {
                return ShapeUtilities.createDiamond(2.0f);
            }
        });

        //set upper and lower bounds of graph
        NumberAxis yAxis=(NumberAxis) plot.getRangeAxis();
        yAxis.setAutoRangeIncludesZero(false);
        yAxis.setUpperBound(upperbound);
        yAxis.setLowerBound(lowerbound);

        //set line color and labels of points
        plot.getRenderer().setSeriesPaint(0, Color.magenta);
        plot.getRenderer().setSeriesPaint(1, Color.green);
        plot.getRenderer().setSeriesPaint(2, Color.black);
};

but when i set the series paint, it doesn't work. the color is still blue for the 3 lines.

any help would be appreciated :-)
