使用Customiser Chart Class有哪些步骤？

问题描述

我想在报告中自定义我的图表（使用jasperReport和iReport 4.0），此类最小化比例，我如何在每个条形图的顶部添加值并在X轴上垂直写入正确性，因为它们是重叠的（看看附图，这是一团糟吗？

这是类：

 公共类ChartCustomiser实现JRChartCustomizer { 
 
 @Override 
 public void customize（JFreeChart jfc，JRChart jrc）{
 
 CategoryPlot plot =（CategoryPlot）jfc.getPlot（）; 
 ValueAxis verticalAxis = plot.getRangeAxis（）; 
 TickUnits verticalTicks = new TickUnits（）; 
 verticalTicks.add（new NumberTickUnit（1））; 
 verticalTicks.add（new NumberTickUnit（2））; 
 verticalTicks.add（new NumberTickUnit（5））; 
 verticalTicks.add（new NumberTickUnit（10））; 
 verticalAxis.setStandardTickUnits（verticalTicks）; 
抛出新的UnsupportedOperationException（尚不支持。）; 
} 
} 
  

我希望图表看起来像这样：

  NumberAxis rangeAxis =（NumberAxis）plot.getRangeAxis （）; 
 rangeAxis.setVerticalTickLabels（true）; 
  

I want to customised my charts in my reports (using jasperReport and iReport 4.0) ,this class minimise the scale ,how can I also add value on top of each bar and write the properity on X axis vertically because their are overlapping (look at the attach chart it's a mess)?

this is the class:

public class ChartCustomiser implements JRChartCustomizer{

 @Override
 public void customize(JFreeChart jfc, JRChart jrc) {

  CategoryPlot plot = (CategoryPlot)jfc.getPlot();
  ValueAxis verticalAxis = plot.getRangeAxis();
  TickUnits verticalTicks = new TickUnits();
  verticalTicks.add(new NumberTickUnit(1));
  verticalTicks.add(new NumberTickUnit(2));
  verticalTicks.add(new NumberTickUnit(5));
  verticalTicks.add(new NumberTickUnit(10));
  verticalAxis.setStandardTickUnits(verticalTicks); 
  throw new UnsupportedOperationException("Not supported yet.");
 }
}

I want a chart look like this:

解决方案

you can try this:

NumberAxis rangeAxis = (NumberAxis)plot.getRangeAxis();
rangeAxis.setVerticalTickLabels(true);
