Item Labels are Not Rotating in My jFreeChart

[Steve Dyke]

For some reason the Item Labels are not rotating.

private JFreeChart createChart(CategoryDataset dataset) {
        
        // create the chart...
        JFreeChart chart = ChartFactory.createBarChart(
            "Rejection Tags By Disposition for ",       // chart title
            "Date",               // domain axis label
            "No of Rejections",                  // range axis label
            dataset,                  // data
            PlotOrientation.VERTICAL, // orientation
            true,                     // include legend
            true,                     // tooltips?
            false                     // URLs?
        );

        // NOW DO SOME OPTIONAL CUSTOMISATION OF THE CHART...

        // set the background color for the chart...
        chart.setBackgroundPaint(Color.white);

        // get a reference to the plot for further customisation...
        CategoryPlot plot = (CategoryPlot) chart.getPlot();
        plot.setBackgroundPaint(Color.lightGray);
        plot.setDomainGridlinePaint(Color.white);
        plot.setDomainGridlinesVisible(true);
        plot.setRangeGridlinePaint(Color.white);
       
        CategoryAxis domainAxis = plot.getDomainAxis();
        domainAxis.setCategoryLabelPositions(CategoryLabelPositions.UP_45);
        
        BarRenderer renderer = (BarRenderer) plot.getRenderer();
        renderer.setBaseItemLabelsVisible(true);
        renderer.setBaseItemLabelGenerator(new StandardCategoryItemLabelGenerator());
        
        for(int x = 0;x<5;x++){
        	renderer.setSeriesItemLabelFont(x, new Font("Times New Roman",Font.PLAIN,10));
        	renderer.setSeriesPositiveItemLabelPosition(x,   
        			new ItemLabelPosition(ItemLabelAnchor.OUTSIDE3, TextAnchor.BOTTOM_LEFT, TextAnchor.BOTTOM_LEFT, -45.0));
        }
        
        //CategoryItemLabelGenerator cLabels = renderer.getBaseItemLabelGenerator();
        //cLabels.
        
        return chart;
    }

Renderer not associated with the chart?

I thought this line was the association. And I am getting the font change just not the rotation. How can I make the association?

BarRenderer renderer = (BarRenderer) plot.getRenderer();

(It is probably too late for Steve, but in case somebody is facing the same problem)

new ItemLabelPosition(ItemLabelAnchor.OUTSIDE3, TextAnchor.BOTTOM_LEFT, TextAnchor.BOTTOM_LEFT, -45.0)

Do not use degrees, but radians. Which means, in your case :

new ItemLabelPosition(ItemLabelAnchor.OUTSIDE3, TextAnchor.BOTTOM_LEFT, TextAnchor.BOTTOM_LEFT, - Math.PI / 4)

This is a common mistake, everybody do it the first time.

Thanks for the help.

I tried this but still did not work. The only way I got the results I wanted was to abandon the ChartFactory and build the chart from scratch.
