Creating Charts in AngularJS

Recommended Posts

I have divided the complete process into the following four easy-to-understand steps:

  1. Include the required JavaScript files
  2. Create the AngularJS app
  3. Define the chart controller
  4. Render the chart

Step 1: Include the required JavaScript files

We need the following three JavaScript dependencies to render our chart:

  1. AngularJS Library
  2. FusionCharts core package JS files
  3. FusionCharts Angular charts plugin

We will include all the above files using the <script> tag, as shown in the code below:

        <!-- including AngularJS library -->
        <script type="text/javascript" src="path/to/angular.min.js"></script>

        <!-- including FusionCharts core package files -->
        <script type="text/javascript" src="path/to/fusioncharts.js"></script>
        <script type="text/javascript" src="path/to/fusioncharts.charts.js"></script>

        <!-- including FusionChart Angular charts plugin -->
        <script type="text/javascript" src="path/to/angular-fusioncharts.min.js"></script>

Step 2: Create the AngularJS app

Next, we need to create the Angular app and inject the ng-fusioncharts module, which is provided by the plugin that we have included in the previous step. This is how we do it:

var app = angular.module('myChartApp', ['ng-fusioncharts']);

Step 3: Define Chart Controller

In this step, we will define a controller for our app. To achieve this, we will augment the controller scope with the dataSource and the chart configurations:

app.controller('chartController', function($scope) {
 	// chart datasource
	 $scope.dataSource = {
		 "chart": {
			// caption configuration
         "caption": "Highest Paid Actors",
         "captionFontBold": "0",
         "captionFontSize": "20",
		 // more chart properties - explained later
		 "data": [{
			 "label": "Leonardo",
			 "value": "1"
		 	}, //more chart data

Step 4: Render the Chart

We are almost done now. To render the chart, we will add the fusioncharts directive inside the <div> tag where chart will be rendered. This is how we will do it:

<div ng-controller="chartController">
		 width= "100%"
		 height= "400"
		 type= "bar2d"
		 dataFormat= "json"
		 dataSource= "{{dataSource}}">

When you’ve executed the above code, you should be seeing a live bar 2D chart. If your chart didn’t render, or you want to see the source code, check out this JSFiddle example.
