Tips for starting an AngularJS directive when its name is determined by ng-class functionality

I have developed several custom AngularJS directives to display Highstock graphs, such as myGraphEff and myGraphEnergy.

Currently, I am working on integrating these graphs into a layout that includes a sidebar. The sidebar will list the names of each graph using "li" elements, and when clicked, the corresponding graph should be loaded.

Below is the code snippet from my controller:

var app = angular.module('app', []); 
app.controller('myController', function($scope,$http) {

    $scope.showingGraphs= [{name:"My Graph Eff",dir:"my-graph-eff"},{name:"My Graph Energy",dir:"my-graph-energy"}];

    $scope.displaingGraph= $scope.showingGraphs[0].dir;

    $scope.loadData = function(graphType){

        $scope.displaingGraph= graphType;
        $http.get('/reports/get-graph-data',{params:{"chartType": graphType}})
        .then(function(response) {
             $scope.data = response.data;
        }); 
    }

});

Next, here is an excerpt of the HTML code:

<div class="box-content">
        <div class="span8">
            <div ng-class="displaingGraph" items="data" style="height: 296px;"></div>
        </div>

        <div class="sparkLineStats span4 widget green" onTablet="span5" onDesktop="span4" >

            <ul  class="unstyled onhover" >
                <li ng-repeat="graph in showingGraphs" ng-click="loadData(graph.dir);">{{ graph.name }}</li>
            </ul>
        </div>
    </div>

The structure of my directive is as follows:

app.directive('myGraphEff', function () {
  return {
    restrict: 'C',
    replace: true,
    scope: {
      items: '='
    },
    controller: function ($scope, $element, $attrs) {

    },
    template: '<div id="container" style="margin: 0 auto">not working</div>',
    link: function (scope, element, attrs) {
      var chart = new Highcharts.stockChart({
        chart: {
          renderTo: 'container',
          type: 'area'
        },
        title: {
          text: 'my graph eff'
        }

      });
      scope.$watch("items", function (newValue) {
        chart.series[0].setData(newValue, true);
      }, true);

    }
  }
});

There seems to be an issue when using ng-class to load the directive content. While loading the directive directly with its class works fine, using ng-class does not render the content properly.

Upon inspecting the rendered HTML in the browser, I noticed that the class is correctly applied to the element, but the content is missing when using ng-class.

The main goal is to change the displayed graph when a user clicks on its name. What could be causing this issue, and how can it be resolved?
