            }
        },
        series: [{
            name: names[0],
            data: janeData
        }, {

            data: joneData
        }]
    });
    }


  }

});

I want it look like same as in jquery ? can we pass variable in directive using scope?

Answer 1

You need to pass the parameters from the isolated scope of your directive, and then inside your directive you need to use $ on directive element to make highcharts method available.

Markup

<chart-test chart-title="chartTitle" x-axisarry="xAxisarry" 
y-axis="yAxis" json-data="janeData" names="names"></chart-test>

Controller

.controller('MainCtrl', function($scope) {
    $scope.chartTitle = "";
    $scope.xAxisarry = ['Apples', 'Bananas', 'Oranges'];
    $scope.yAxis = 'Fruit eaten';
    $scope.data = {
      jane: [1, 0, 4],
      jone: [5, 7, 3]
    };
    $scope.names = ["jane", "jone"];

})

Directive

.directive('chartTest', function() {
    return {
      restrict: 'E',
      scope: {
        chartTitle: '=',
        xAxisarry: '=',
        yAxis: '=',
        jsonData: '=',
        names: '='
      },
      link: function(scope, element, attrs) {
        $(element).highcharts({
          chart: {
            type: 'bar'
          },
          title: {
            text: scope.chartTitle
          },
          xAxis: {
            categories: scope.xAxisarry
          },
          yAxis: {
            title: {text: 'Fruit eaten'}
          },
          series: [{
            name: scope.names[0],
            data: scope.jsonData['jane']
          }, {
            name: scope.names[1],
            data: scope.jsonData['jone']
          }]
        });
      }
    }
});
