Hi, These days i am working on some reports which nedds graphs. In there i have a Line Chart with 2 category series. and here i am using a chart customizer class to customize the class. Is there any way to get a reference to thse two category series with in the chart customizer. i found a way fo getting a reference to the plot but not these category seriess. public class LineChartCustomizer extends JRAbstractChartCustomizer { public void customize(JFreeChart chart, JRChart jasperChart) { LineAndShapeRenderer renderer = (LineAndShapeRenderer) chart.getCategoryPlot().getRenderer(); //renderer.setSeriesPaint(1, Color.green); //renderer.setSeriesPaint(4, Color.orange); // get a reference to the plot for further customisation... final CategoryPlot plot = chart.getCategoryPlot(); Do you guys have any idea about this. appreciate your help Thanks, Keth

Hi Matt, Thanks for the reply. i was able to solve the problem. i posting it here so others can refer it public class LineChartCustomizer extends JRAbstractChartCustomizer { public void customize(JFreeChart chart, JRChart jasperChart) { LineAndShapeRenderer renderer = (LineAndShapeRenderer) chart.getCategoryPlot().getRenderer(); renderer.setSeriesPaint(1, Color.green); renderer.setSeriesPaint(4, Color.orange); // get a reference to the plot for further customisation... final CategoryPlot plot = chart.getCategoryPlot(); // change the auto tick unit selection to integer units only... final NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis(); rangeAxis.setTickUnit(new NumberTickUnit(1)); rangeAxis.setUpperBound(24); chart.setTitle("Setting the title "); } } Your blog post post was very helpful for achive this. Thanks keth

Hi, In my Current project i need to create a Line Graph. i am using Jasper 3.5. But the problem is i can not number my Y Axis continuously. after i define min and max values for Y axis it shows only the range of values instead of continous numbering though the Axis.(it shows 0,5,10,15 instead of 1,2,3,4,5,6,7,8...etc). Can any one help me to solve this? Can we use chart customizer to solve this? any help greatly appreciate Thanks, Keth
