what ver of jfreechart are you using? this works with the latest (1.0.13):
<cfscript>
color=createObject("java","java.awt.Color");
plotOrientation=createObject("java","org.jfree.chart.plot.PlotOrientation");
nf=createObject("java","java.text.NumberFormat").getInstance();
/*
pay attention: label format, format where format is either some instance of
NumberFormat or DateFormat
leave you to fiddle w/placement,formatting, etc.
*/
itemLabelGenerator=createObject("java","org.jfree.chart.labels.StandardCategoryItemLabelGenerator").init(
"php sucks {0}!",nf);
dataset=createObject("java","org.jfree.data.category.DefaultCategoryDataset").init();
dataset.addValue(1.0, "1", "Column 1");
dataset.addValue(5.0, "1", "Column 2");
dataset.addValue(3.0, "1", "Column 3");
dataset.addValue(2.0, "2", "Column 1");
dataset.addValue(3.0, "2", "Column 2");
dataset.addValue(2.0, "2", "Column 3");
chart=createObject("java","org.jfree.chart.ChartFactory").createBarChart3D(
"it's a bar chart stupid", // title
"category", // domain axis label
"value", // range axis label
dataset, // which data
plotOrientation.VERTICAL, // direction
false, // legend
false, // tooltips
false // urls
);
chart.setBackgroundPaint(Color.white);
// plot
plot=chart.getCategoryPlot();
plot.setBackgroundPaint(Color.lightGray);
plot.setRangeGridlinePaint(Color.white);
// renderer
renderer=plot.getRenderer();
renderer.setSeriesPaint(0,color.gray);
renderer.setSeriesPaint(1,color.orange);
renderer.setDrawBarOutline(false);
renderer.setItemMargin(0.0);
renderer.setItemLabelPaint(color.red);
renderer.setItemLabelsVisible(javacast("boolean","true"));
renderer.setItemLabelGenerator(itemLabelGenerator);
// axis
categoryAxis = plot.getDomainAxis();
categoryAxis.setCategoryMargin(0.0);
// wrap it up
chartImage=chart.createBufferedImage(650,450);
imageIO=createObject("java","javax.imageio.ImageIO");
outFile=createObject("java","java.io.File");
// some write accessible path
outFile.init("path_to_image_file\labels.png");
imageIO.write(chartImage,"png",outFile);
