Dojo chart issues in clusterd column chart

问题:

Firstly say to all of you i am new to dojo charts. I made a dojo clustered column chart. Here i am made different series for show clustered chart. But here is my graph shows different color for different bedrooms with their respective project name. But i want my graph shows like different projects wise color with their respective bedrooms. For this problem i am facing from last 5 days but can not got any proper solutions. I searched from Stack Overflow suggestions but i am failed. So please tell me how can i show my graph with bedroom wise with different different colored projects.Here i am making a jsfiddle link[ http://jsfiddle.net/sunman/rV9g4/ ] .

Here is my code index.php

      $series1 =array();
      $result = array();
     $Bedroom_Area=$conn->prepare("SELECT  penthouse.*,projects_detail.Project_name From penthouse 
       left join projects_detail on penthouse.project_id=projects_detail.project_id where penthouse.project_id in (1,8,14,29,33,101)
     ");
    $Bedroom_Area->execute();
   //$i=0;
while($result_Bed=$Bedroom_Area->fetch()){

    $series1[] =  array('month' => $result_Bed['Project_name'],'BedRoom2'=> $result_Bed['bed_room2'], 
    'BedRoom3' => $result_Bed['bed_room3'],'BedRoom4' => $result_Bed['bed_room4'],
  'BedRoom5' => $result_Bed['bed_room5']);
    //$array1[]= array("value" => $i, "text" => $result_Bed['Project_name']);
    //$i++;

  }
   print json_encode($series1,JSON_NUMERIC_CHECK);


         var switchClustering;

         require(["dojo/_base/declare", "dojo/ready", "dojo/dom",              "dojox/charting/Chart",

  chart.title = "Bedroom Comparision";
  chart.render();


  on(dom.byId("chart"), tap.doubletap, switchClustering);

    });
    });

Please refer above code and tell me how can got my graph bedroom wise with different different colored projects.
