我想顯示莫里斯線圖,但該行不顯示出來,這樣莫里斯線不工作

screen shot of morris.line

這是我的代碼

<div class="panel-body"> 
    <div id="morris_area_operation"></div> 

    <?php 
      $operation_quey = DB::table('station_vehicule') 
        ->select('operation_date as date', 
          DB::raw('COUNT(operation_date) as nombre')) 
        ->where('operation_name', '=', 'Carburant') 
        ->groupBy('operation_date') 
        ->orderBy('operation_date', 'asc') 
        ->get(); 
    ?> 

    <script>      
     var data_collection = <?php echo json_encode($operation_quey); ?>; 

     new Morris.Line({ 
      element: 'morris_area_operation', 
      data: data_collection, 
      xkey: 'date', 
      ykeys: 'nombre', 
      xLabelFormat: function(x) { 
        return x.toDateString(); 
      }, 
      ymax: 'auto', 
      hideHover: true, 
      resize: true 
      }); 
     </script> 

</div> 

正如你所看到的,數據存在(日期和數據)但我看不到圖表中的行
