}
},
xAxis: { // Primary xAxis
categories: $scope.nameMonths,

enabled: true
},
min:0
},
yAxis: [{ // Primary yAxis
title: {

},
labels: {
formatter: function () {
return Highcharts.numberFormat(this.value / 1000000,'0') + ' mil';
}
}
}, { // Secondary yAxis
title: {
text: 'Balance'
},
labels: {
formatter: function () {
return Highcharts.numberFormat(this.value / 1000000,'0') + ' mil';
}
},
}],
series: [{
name: 'AGP - Goods Receipt',
type: 'column',
stacking: 'normal',
stack: '1',
data: $scope.dataLogisticGIGR_AGP_GR,
color: $rootScope.getColor('AGP Ext'),

pointFormat: '<span style="color:{series.color}">{series.name}: {point.y:,.0f}</span><br/>'
}
},{
name: 'AGP - Goods Issue',
type: 'column',
stacking: 'normal',
stack: '1',
data: $scope.dataLogisticGIGR_AGP_GI,
color: $rootScope.getColor('AGP Int'),
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}: {point.y:,.0f}</span><br/>'
}
},{
name: 'AGP - Balance',
type: 'spline',

pointFormat: '<span style="color:{series.color}">{series.name}: {point.y:,.0f}</span><br/>'
}
},{
name: 'AI - Goods Receipt',
type: 'column',
stacking: 'normal',
stack: '3',
data: $scope.dataLogisticGIGR_AI_GR,
color: $rootScope.getColor('AI'),
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}: {point.y:,.0f}</span><br/>'
}
},{
name: 'AI - Goods Issue',
type: 'column',
stacking: 'normal',
stack: '3',
data: $scope.dataLogisticGIGR_AI_GI,
color: $rootScope.getColor('AP 2'),
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}: {point.y:,.0f}</span><br/>'
}
},{

type: 'spline',
data: $scope.dataLogisticGIGR_AI_Balance,
color: $rootScope.getColor('AP'),
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}: {point.y:,.0f}</span><br/>'
}
}],
title: {
text: ''
},
loading: false
};
in this is my code in directive highchart
'use strict';
angular.module('chartsExample.directives',[])
.directive('chart', function () {
return {
restrict: 'E',
template: '<div></div>',
scope: {
chartData: "=value"
},
transclude:true,
replace: true,
link: function (scope, element, attrs) {
var chartsDefaults = {
chart: {
renderTo: element[0],
type: attrs.type || null,
height: attrs.height || null,
width: attrs.width || null
}
};
//Update when charts data changes
scope.$watch(function() { return scope.chartData; }, function(value) {
if(!value) return;
// We need deep copy in order to NOT override original chart object.
// This allows us to override chart data member and still the keep
// our original renderTo will be the same
var newSettings = {};
angular.extend(newSettings, chartsDefaults, scope.chartData);
var chart = new Highcharts.Chart(newSettings);
});
}
};
});
Thank's....
