We came across one issue, when we created a Stacked Bar Chart using JFree chart the label names are not visible totally as below Screenshot.
Query results:
Stacked Bar Chart:
By using class customizer we can solve the above problem
Step 1: Create a Java Project and create a java class as below
package com.customchart.StackedBar;
import net.sf.jasperreports.engine.JRChart;
import net.sf.jasperreports.engine.JRChartCustomizer;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.axis.CategoryAxis;
import org.jfree.chart.plot.CategoryPlot;
public class PlotBarchartEnclosing
implements JRChartCustomizer
{
public void customize(JFreeChart chart, JRChart jasperChart)
{
Log log = LogFactory.getLog(PlotBarchartEnclosing.class);
CategoryPlot plot = (CategoryPlot)chart.getPlot();
CategoryAxis categoryAxis = plot.getDomainAxis();
categoryAxis.setMaximumCategoryLabelLines(3);
categoryAxis.setMaximumCategoryLabelWidthRatio(3.0F);
}
}
Step 2 : Export the project to JAR
Step 3 : Add the JAR in Jasper studio
Step 4 : Attach this JAR to class customizer by giving packagename.classname in class customizer
Step 5 : Run the report and see the output as follows with full label names:
