如何將圖形包含在codeigniter導出excel中

Question

我有用戶列表與評論count.I出口excel使用下面的libaraies和代碼。 如何在Excel表格中包含圖表。

這裏是我的輸出： 例如爲：

Sno USER  CommentCount 
1  User1 10 
2  User2 12 
3  User3 21 

如何使用笨，形成了Excel裏面圖形或圖表。

庫函數：

class Export{  
    function to_excel($array, $filename) { 
     header('Content-type: application/vnd.ms-excel'); 
     header('Content-Disposition: attachment; filename='.$filename.'.xls');   
     $h = array(); 
     foreach($array as $row){ 
      foreach($row as $key=>$val){ 
       if(!in_array($key, $h)){ 
        $h[] = $key; 
       } 
      } 
     } 
     echo '<table><tr>'; 
     foreach($h as $key) { 
      $key = ucwords($key); 
      echo '<th>'.$key.'</th>'; 
     } 
     echo '</tr>'; 
     foreach($array as $row){ 
      echo '<tr>'; 
      foreach($row as $val) 
      $this->writeRow($val); 
     } 
     echo '</tr>'; 
     echo '</table>'; 
    } 
    function writeRow($val) { 
     echo '<td>'.utf8_decode($val).'</td>';    
    } 
} 

控制器代碼：

public function userlist(){  
    $sql = $this->export_model->user_export();  
    $this->export->to_excel($sql, 'UserList'); 
}

最後我用PHP EXCEL得到它。代碼如下

include "Classes/PHPExcel.php"; 
    header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); 
    header('Content-Disposition: attachment;filename="graphdemo.xlsx"'); 
    header('Cache-Control: max-age=0'); 
    $workbook = new PHPExcel(); 

    $objRichText = new PHPExcel_RichText(); 
    $objBold = $objRichText->createTextRun('Name'); 
    $objBold->getFont()->setBold(true); 
    $workbook->getActiveSheet()->getCell('A1')->setValue($objRichText); 

    $objRichText = new PHPExcel_RichText(); 
    $objBold = $objRichText->createTextRun('Sharing Count'); 
    $objBold->getFont()->setBold(true); 
    $workbook->getActiveSheet()->getCell('B1')->setValue($objRichText); 

    $workbook->setActiveSheetIndex(0); 
    $sheet = $workbook->getActiveSheet(); 
    $sheet->getPageMargins()->setTop(0.6); 
    $sheet->getPageMargins()->setBottom(0.6); 
    $sheet->getPageMargins()->setHeader(0.4); 
    $sheet->getPageMargins()->setFooter(0.4); 
    $sheet->getPageMargins()->setLeft(0.4); 
    $sheet->getPageMargins()->setRight(0.4); 
    $workbook->getProperties()->setTitle("Demo"); 
    $workbook->getProperties()->setCreator("Demo"); 
    $workbook->getProperties()->setLastModifiedBy("Demo"); 
    $workbook->getProperties()->setCompany("Demo"); 


    $Requete = "SELECT COUNT(*) As cnt , name FROM `users` GROUP BY user_id "; 
    $result = mysql_query($Requete); 
    while ($row = mysql_fetch_array($result)){ 
     $bname[] = $row["name"]; 
     $bk_co[] = $row["cnt"];   
    } 
    $data =$bname; 
    $row = 2; 
    foreach($data as $point) { 
     $sheet->setCellValueByColumnAndRow(0, $row++, $point); 
    }  
    $data = $bk_co; 
    $row = 2; 
    foreach($data as $point) { 
     $sheet->setCellValueByColumnAndRow(1, $row++, $point); 
    } 

    $values = new PHPExcel_Chart_DataSeriesValues('Number', 'Worksheet!$B$1:$B$10'); 
    $categories = new PHPExcel_Chart_DataSeriesValues('String', 'Worksheet!$A$1:$A$10'); 
    $series = new PHPExcel_Chart_DataSeries(
    PHPExcel_Chart_DataSeries::TYPE_BARCHART,   
    PHPExcel_Chart_DataSeries::GROUPING_CLUSTERED, 
    array(0),           
    array(),           
    array($categories),        
    array($values)         
    ); 
    $series->setPlotDirection(PHPExcel_Chart_DataSeries::DIRECTION_COL); 
    $layout = new PHPExcel_Chart_Layout(); 
    $plotarea = new PHPExcel_Chart_PlotArea($layout, array($series)); 
    $chart = new PHPExcel_Chart('sample', null, null, $plotarea); 
    $chart->setTopLeftPosition('F2'); 
    $chart->setBottomRightPosition('N25'); 
    $sheet->addChart($chart); 
    $writer = PHPExcel_IOFactory::createWriter($workbook, 'Excel2007'); 
    $writer->setIncludeCharts(TRUE); 
    $writer->save('php://output');
