Need help separtating bars on my chart

[Steve Dyke]

I have the following code that generates an overlaid chart with three data series. Two bars and one line. I nees the two bars to be displayed side by side instead of on top of each other.

public JFreeChart chart;

public MakeAChart2(){

chart = createOverlaidChart();
        
}

private JFreeChart createOverlaidChart() {
 
        // create plot ...
        final IntervalXYDataset data1 = createDataset1();
        final XYItemRenderer renderer1 = new XYBarRenderer(0.20);
        renderer1.setToolTipGenerator(
            new StandardXYToolTipGenerator(
                StandardXYToolTipGenerator.DEFAULT_TOOL_TIP_FORMAT,
                new SimpleDateFormat("d-MMM-yyyy"), new DecimalFormat("0.00")
            )
        );
        final DateAxis domainAxis = new DateAxis("Month");
        domainAxis.setTickMarkPosition(DateTickMarkPosition.MIDDLE);
        final ValueAxis rangeAxis = new NumberAxis("Hours");
        final XYPlot plot = new XYPlot(data1, domainAxis, rangeAxis, renderer1);
        //final double x = new Day(9, SerialDate.MARCH, 2002).getMiddleMillisecond();
        //final XYTextAnnotation annotation = new XYTextAnnotation("Hello!", x, 10000.0);
        //annotation.setFont(new Font("SansSerif", Font.PLAIN, 9));
        //plot.addAnnotation(annotation);
 
        // add a second dataset and renderer...
        final XYDataset data2 = createDataset2();
        final XYItemRenderer renderer2 = new StandardXYItemRenderer();
        renderer2.setToolTipGenerator(
            new StandardXYToolTipGenerator(
                StandardXYToolTipGenerator.DEFAULT_TOOL_TIP_FORMAT,
                new SimpleDateFormat("d-MMM-yyyy"), new DecimalFormat("0.00")
            )
        );
        plot.setDataset(1, data2);
        plot.setRenderer(1, renderer2);

        );

        plot.setRenderer(2, renderer3);

That is a lot of code and docs to dig through on an api I have never seen but I do not see any vars in Plot that can be used to set each bar at some X-Position on a chart. There is plenty for Y-Scaling and putting a graphical up. Did you write this code? Looks like it came from an IDE ( a remarkable one )

Use ClusteredXYBarRenderer instead of XYBarRenderer:
ClusteredXYBarRenderer renderer1 = new ClusteredXYBarRenderer(0.20, false);

Also, combine series1 and series3 into one dataset like this:
TimeSeriesCollection tsc = new TimeSeriesCollection();
tsc.addSeries(series1);
tsc.addSeries(series3);
tsc.setXPosition(TimePeriodAnchor.MIDDLE);
return tsc;

Thanks for your input, but did you really think it was necessary to reply to a thread that is almost a year old?
