Мой HTML:

<div class="graph-display" ng-controller="jsonServerBox">
    <div class="bar-chart-box" ng-repeat="module in ocw.modules"> 
        <canvas class="chart chart-bar" data="{{module.data}}" labels="{{module.labels}}" series="{{module.series}}"></canvas>
    </div>
</div>

Мой JS:

app.controller('jsonServerBox', function($scope, $http) {
  var json = $http.get('serverbox.json').then(function(res){
          return res.data;
        });
  $scope.ocw = json;    
    });

Диаграмма не отображается, не знаете почему? Я не получаю никаких ошибок в консоли.

ОБНОВЛЕНИЕ: МОЙ JSON FILES CONTENT
