retrieved from DB(mysql), but i got issue during add columns and
displayed chart tooltip display wrong column label.

my code is :
  private AbstractDataTable createTable(String xmldata) {
          DataTable data = DataTable.create();

                data.addColumn(ColumnType.STRING, "Year");
                data.addColumn(ColumnType.NUMBER, "Gopal","0");
                data.addColumn(ColumnType.NUMBER, "Shanthi","1");
                data.addColumn(ColumnType.NUMBER, "Senthil","2");

                // XML PARSE
                final Document xmlDoc = XMLParser.parse(xmldata);
                final Element root = xmlDoc.getDocumentElement();
                XMLParser.removeWhitespace(xmlDoc);
                final NodeList profiles = root.getElementsByTagName("DATA");

                int rowIndex = 0, columnIndex = -1;

                //data.addRows(profiles.getLength());
                for (int i = 0; i < profiles.getLength(); i++) {
                        data.addRow();
                        final Element year = (Element) profiles.item(i);

                        int noofEmp = 
year.getElementsByTagName("INDIVIDUALS").getLength();

                        data.setValue(rowIndex, ++columnIndex, year
                                        .getAttributeNode("YEAR").getValue());
                        for (int j = 0; j < noofEmp; j++) {
                                ++columnIndex;
                                final Element emp = (Element) 
year.getElementsByTagName(
                                                "INDIVIDUALS").item(j);
                                final Element emp_leave = (Element) 
emp.getElementsByTagName(
                                                "T_LEAVE").item(0);
                                final Element emp_name = (Element) 
emp.getElementsByTagName(
                                "NAME").item(0);

                                //Window.alert("Num of Record"+noofEmp);
                                data.addColumn(ColumnType.NUMBER, emp_name
                                                
.getFirstChild().getNodeValue());
                                        
//data.setColumnLabel(columnIndex,emp_name
                                                
//.getFirstChild().getNodeValue());

                                                //Window.alert("Name : 
"+emp_name
                                //              
.getFirstChild().getNodeValue());

                                data.setValue(rowIndex, columnIndex, 
Integer.parseInt(emp_leave
                                                
.getFirstChild().getNodeValue()));
                                //Window.alert("row 
Column"+data.getValueInt(rowIndex,
columnIndex));

                        }
                        rowIndex++;
                        columnIndex = -1;
                        }
                Window.alert("Row Count ,Column Count"+data.getNumberOfRows()+"
"+data.getNumberOfColumns());


                return data;
  }
