angularjs & highcharts - setting up properties in directive - angularjs

Question

I currently have this as my directive:
app.directive('highchart', function () {
return {
restrict: 'E',
template: '<div></div>',
replace: true,
link: function(scope, element, attrs) {
scope.$watch(function() { return attrs.chart; }, function() {
if (!attrs.chart) return;
var chart = JSON.parse(attrs.chart);
$(element[0]).highcharts(chart);
});
}
};
})
And this is my controller:
function ProdSvcViewsCtrl($scope, $routeParams, $http, $location) {
$scope.example_chart = get_chart();
function get_chart() {
return {
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
plotOptions: {
series: {
name: 'Page Views',
color:'#FFFFFF',
cursor: 'pointer',
point: {
events: {
click: function () {
alert('Category: ' + this.category + ', value: ' + this.y);
}
}
},
}
},
chart: {
renderTo: 'container',
backgroundColor : {
linearGradient : [0, 0, 0, 400],
stops : [
[0, 'rgb(100, 100, 100)'],
[1, 'rgb(50, 50, 50)']
]
},
plotBackgroundColor: 'rgba(255, 255, 255, 0.1)',
width: 775,
height: 300,
},
title: {
text: "Product Page Views",
align: "center",
y: 15,
style: {
color: "#ffffff",
fontSize: "18px",
fontWeight: 500,
fontFamily:'Calibri,Helvetica,Arial'
}
},
legend: {
backgroundColor: 'transparent',
color:'#FFFFFF',
layout: 'horizontal',
floating: true,
align: 'left',
verticalAlign: 'top',
x: 60,
y: 1,
shadow: false,
border: 0,
borderRadius: 0,
borderWidth: 0
},
series: [{
data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}]
};
}
}
How would I migrate the properties over to the directive from my controller so they can be dynamic depending upon what attributes I apply to the respective directive, ie, color, width, etc?

Answer 1

In your directive you could add watches to the parts of the chart you want to be dynamic.
This is the approach taken by this directive: https://github.com/pablojim/highcharts-ng
