Pie Chart only legends visible

[lucky7456969]

Hello, I have built a JRBeanCollectionDataSource and confirmed that there was data in it. I have set the max number of slices to be 35 and the expression is set to the type of product, and the values are the percentage calculated off the SQL query built before the JRBeanCollectionDataSource is built 

@Override
    public void printReport(List data) {
               int m = getCurrentMonth();
               List<Sales> lSales = new ArrayList<>();
               
               int[] lastm = getMonths(m);
               
               
              List<Sales> ls = new ArrayList<>();
              List<SalesChart> lsc = new ArrayList<>();
               
              try {
                  
                  
                    String sql = getSQL(m);
                    ResultSet rs = getDB().query(sql);
                     

                    while (rs.next())
                    {
                        
                        Sales s = new Sales();
                        s.setType(rs.getString("type"));
                        s.setMonth(m);
                        s.setNs(rs.getInt("NS"));
                        s.setPercent(rs.getDouble("percent"));
                        
                        
                        SalesChart sc = new SalesChart();
                        sc.setType(s.getType());
                        sc.setMonth(s.getMonth());
                        sc.setNs(s.getNs());
                        sc.setPercent(s.getPercent());
                        
                        
                        
                        
                        /*sc.setType(s.getType());
                        sc.setMonth(s.getMonth());
                        sc.setNs(s.getNs());*/
                        
                        lsc.add(sc);
                        
                        s.setListOfSales(lsc);
                        
                        ls.add(s);
                        
                        
                        
                        
                    }       
                    
                        
                        
                        


                  
                    
                    
                    JRBeanCollectionDataSource beanCollectionDataSource = new JRBeanCollectionDataSource(ls,false);
   
                             
                             
                     JasperPrint    jp = null;
                       
                     jp = JasperFillManager.fillReport(getClass().getResourceAsStream("/Reporting/SalesReport6MthByProdType.jasper"), null, beanCollectionDataSource);
                        
                      

                        JRViewer test = new JRViewer(jp);
          
                        f.add(test);
                        f.setSize(new Dimension(1000,600));
                       
                        f.setVisible(true);
                } catch (SQLException ex) {
                    Logger.getLogger(SalesReport6MthByCustType.class.getName()).log(Level.SEVERE, null, ex);
                } catch (JRException ex) {
            Logger.getLogger(SalesReport6MthByCustType.class.getName()).log(Level.SEVERE, null, ex);
        }
     }

Wonder why this won't work. I had a stacked bar previously which worked perfectly with this coding.

 

Thanks Jack
