Rendering Highcharts using Angular js Directives - angularjs

Question

I am new to Angular JS and trying to render my highcharts (Basic Line) by creating a directive. Please tell me the approach I should follow here. Any help would be appreciated.
Here is my script for the highcharts:
<script type="text/javascript">
$(function () {
$('#container').highcharts({
chart: {
type: 'line',
marginRight: 130,
marginBottom: 25
},
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
series: [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}, {
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
}, {
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
});
});
</script>

Example of pie chart:
http://jsfiddle.net/csTzc/
function MyCtrl($scope, limitToFilter) {
$scope.ideas = [
['ideas1', 1],
['ideas2', 8],
['ideas3', 5]
];
$scope.limitedIdeas = limitToFilter($scope.ideas, 2);
}
angular.module('myApp', [])
.directive('hcPie', function () {
return {
restrict: 'C',
replace: true,
scope: {
items: '='
},
controller: function ($scope, $element, $attrs) {
console.log(2);
},
template: '<div id="container" style="margin: 0 auto">not working</div>',
link: function (scope, element, attrs) {
console.log(3);
var chart = new Highcharts.Chart(options);
scope.$watch("items", function (newValue) {
chart.series[0].setData(newValue, true);
}, true);
}
}
});

Answer 2

Alternative implementation here: http://jsfiddle.net/pablojim/Cp73s/
This uses https://github.com/pablojim/highcharts-ng
This allows you to create a highchart with the below html:
<highchart id="chart1" series="chart.series" title="chart.title" options="chart.options"></highchart>
In the above case chart.series is an array of javascript objects representing the series on the chart - these take standard Highcharts options. These are then watched by angularjs for any changes.
chart.options is the highcharts initalisation options - also watched for changes. Although changes to this recreate the entire chart.
chart.title is the highcharts title object - also watched for changes.

app.directive('hcChart', function () {
return {
restrict: 'A',
template: '<div></div>',
scope: {
options: '='
},
link: function (scope , element, attribute) {
Highcharts.chart('chart', {
chartOptions: {
type: 'line'
},
title: {
text: 'Temperature data'
},
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]
}]
});
}
}
});
<div id="chart" hc-chart>Placeholder for generic chart</div>
Make sure highchart lib is added in your index.html
