Chart Customization : Access Chart's Series expression's value in Customize() method

[ankushchhabra]

I am using JasperReports Server 5.0 professional Version.

 

For one of the report, I am using Chart Customizer to customize the color of the bars. Evaluation Time is Report

 

In iReport, i have defined the Series expression as

 

 $F{form} + "(" + $V{month} + ")"  

 

In customize method of Java file, i want to access above expressions' value which are

 

1-sep , 2 - Oct, 3 -Jan , 4 -Feb

 

I have tried the following code to get Series values but no success.

 

  public JRCategorySeries[] categoryList = null ; 

  JRFillCategoryDataset  categoryDS  = (JRFillCategoryDataset)jasperChart.getDataset();

  categoryList = categoryDS.getSeries();

 

  SubCategoryAxis domainAxis = new SubCategoryAxis("");

  domainAxis.setCategoryMargin(0.05);

 

  for (int i = 0 ; i <categoryList.length -1 ; i++ ) {

 

    JRCategorySeries jrcategoryseries = categoryList;

 

    domainAxis.addSubCategory(jrcategoryseries.getSeriesExpression().getText());

  }

 

I need help in accessing series data point in customize method. I will appreciate your comments.
