Getting Started

Requirements

Installation

To install angularjs-fusioncharts library, run:

$ npm install angularjs-fusioncharts --save

To install fusioncharts library:

$ npm install fusioncharts --save

Quick Start

Step 1: Include angular-fusioncharts.js and fusioncharts

In your index.html

  <script type="text/javascript" src="https://github.com/fusioncharts/angularjs-fusioncharts/raw/master/node_modules/fusioncharts/fusioncharts.js"></script>
  <script type="text/javascript" src="https://github.com/fusioncharts/angularjs-fusioncharts/raw/master/node_modules/fusioncharts/fusioncharts.charts.js"></script>
  <script type="text/javascript" src="https://github.com/fusioncharts/angularjs-fusioncharts/raw/master/node_modules/fusioncharts/themes/fusioncharts.theme.fusion.js"></script>
  <script type="text/javascript" src="https://github.com/fusioncharts/angularjs-fusioncharts/raw/master/node_modules/angular/angular.js"></script>
  <script type="text/javascript" src="https://github.com/fusioncharts/angularjs-fusioncharts/raw/master/node_modules/angularjs-fusioncharts/dist/angular-fusioncharts.js"></script>

Step 2: Include ng-fusioncharts in your module

In the app, include ng-fusioncharts as a dependency. If you looking for where to add the dependency, look for the call to angular.module in your code.

angular.module('myApp', ['ng-fusioncharts']);

Step 3: Add the fusioncharts directive

In your HTML, find the section where you wish to add the chart and add a

with the fusioncharts directive. We are assuming it's inside a controller called MyController which would change based on your usage.

  <body ng-app='myApp'>
    ...
    <div  ng-controller="MyController">
      <div
        fusioncharts
        width="600"
        height="400"
        type="column2d"
        datasource="{{dataSource}}">
      </div>
    </div>
    ...
  </body>

Step 4: Populate required variables in controller

In the previous code, we are binding to a scope variable myDataSource, but that hasn't been defined yet. In your controller, set the DataSource as you would for a regular FusionCharts JSON format DataSource (see this tutorial for a general introduction to this format).

app.controller('MyController', function($scope) {
  $scope.dataSource = {
    chart: {
      caption: 'Countries With Most Oil Reserves [2017-18]',
      subCaption: 'In MMbbl = One Million barrels',
      xAxisName: 'Country',
      yAxisName: 'Reserves (MMbbl)',
      numberSuffix: 'K',
      theme: 'fusion'
    },
    data: [
      { label: 'Venezuela', value: '290' },
      { label: 'Saudi', value: '260' },
      { label: 'Canada', value: '180' },
      { label: 'Iran', value: '140' },
      { label: 'Russia', value: '115' },
      { label: 'UAE', value: '100' },
      { label: 'US', value: '30' },
      { label: 'China', value: '30' }
    ]
  };
});

And your chart should display when you load the page.

Using require() syntax

In script.js

//  Require AngularJS
var angular = require('angular');

// Require FusionCharts
var FusionCharts = require('fusioncharts');

// Include angularjs-fusioncharts
require('angularjs-fusioncharts');

// Require Chart modules
var Charts = require('fusioncharts/fusioncharts.charts');

// Initialize Charts with FusionCharts instance
Charts(FusionCharts);

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

app.controller('MyController', [
  '$scope',
  function($scope) {
    $scope.dataSource = {
      chart: {
        caption: 'Countries With Most Oil Reserves [2017-18]',
        subCaption: 'In MMbbl = One Million barrels',
        xAxisName: 'Country',
        yAxisName: 'Reserves (MMbbl)',
        numberSuffix: 'K'
      },
      data: [
        { label: 'Venezuela', value: '290' },
        { label: 'Saudi', value: '260' },
        { label: 'Canada', value: '180' },
        { label: 'Iran', value: '140' },
        { label: 'Russia', value: '115' },
        { label: 'UAE', value: '100' },
        { label: 'US', value: '30' },
        { label: 'China', value: '30' }
      ]
    };
  }
]);

Use a bundler like browserify to bundle the script
See the installation docs here

$ browserify script.js -o bundle.js

In index.html

<html>
  <head>

    <!-- Include compiled bundle in script tag -->
    <script type="text/javascript" src="https://github.com/fusioncharts/angularjs-fusioncharts/raw/master/bundle.js"></script>
  </head>

  <body ng-app="myApp">
    <div ng-controller="MyController">
      <div
        fusioncharts
        width="600"
        height="400"
        type="column2d"
        datasource="{{dataSource}}">
      </div>
    </div>
  </body>
</html>

Load it in browser , Chart should get displayed

Working with Events

Fusincharts events can be subscribed by attaching scope functions to event attributes. All the events attributes start with fcevent- followed by the event name in lowercase

Usage in template :

<fusioncharts
  width="400"
  height="400"
  type="column2d"
  datasource="{{myDataSource}}"
  fcevent-dataplotrollover="rollover(event, args)">
</fusioncharts>

In the given above template, rollover is the scope function that needs to be defined in the controller's code.

For more on this read here

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

app.controller('MyController', function($scope) {
  $scope.myDataSource = {
    chart: {
      caption: 'Countries With Most Oil Reserves [2017-18]',
      subCaption: 'In MMbbl = One Million barrels',
      xAxisName: 'Country',
      yAxisName: 'Reserves (MMbbl)',
      numberSuffix: 'K',
      theme: 'fusion'
    },
    data: [
      { label: 'Venezuela', value: '290' },
      { label: 'Saudi', value: '260' },
      { label: 'Canada', value: '180' },
      { label: 'Iran', value: '140' },
      { label: 'Russia', value: '115' },
      { label: 'UAE', value: '100' },
      { label: 'US', value: '30' },
      { label: 'China', value: '30' }
    ]
  };

  $scope.rollover = function(event, data) {
    console.log(event, data);
  };
});

Get the list of fusioncharts' events

Working with APIs

FusionCharts chart instance is made available from the initialized event. It provides the chart instance as a parameter which can be used to call FusionCharts methods.

In template, we add initialized event

<fusioncharts
  width="400"
  height="400"
  type="column2d"
  datasource="{{myDataSource}}"
  initialized="onInitialized(chart)">
</fusioncharts>
<button ng-click="changeCaption()">Change Chart Caption</button>

In order to use the chart instance, we need to store it.

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

app.controller('MyController', function($scope){
    var chart;
    $scope.datasource = {
       ...// same data as above
      };

      $scope.onInitialized = function(chartObj){
        chart = chartObj;
      }

      $scope.changeCaption = function(){
          chart.setChartAttribute('caption', 'Caption changed');
      }
});

In the given above example, clicking the button changes the caption text to Caption changed

Usage and integration of FusionTime

From fusioncharts@3.13.3-sr.1 and angularjs-fusioncharts@5.0.0, You can visualize timeseries data easily with angular.

Learn more about FusionTime here.

Sample code for FusionTime

If you've included angular-fusioncharts.js and fusioncharts in your html then add the following script tag:

In your index.html

  ...
  <script type="text/javascript" src="https://github.com/fusioncharts/angularjs-fusioncharts/raw/master/node_modules/fusioncharts/fusioncharts.timeseries.js"></script>
  ...

In your script.js

// If you haven't imported angulajs, angularjs-fusioncharts and fusioncharts in your html file and used require() syntax instead then add the following code from START to END:

// START
var angular = require('angular');
var FusionCharts = require('fusioncharts');
require('angularjs-fusioncharts');

// Require TimeSeries module
var TimeSeries = require('fusioncharts/fusioncharts.timeseries');

// Initialize Charts with FusionCharts instance
TimeSeries(FusionCharts);
var app = angular.module('myApp', ['ng-fusioncharts']);
// END

var jsonify = res => res.json();
var dataFetch = fetch(
  'https://s3.eu-central-1.amazonaws.com/fusion.store/ft/data/line-chart-with-time-axis-data.json'
).then(jsonify);
var schemaFetch = fetch(
  'https://s3.eu-central-1.amazonaws.com/fusion.store/ft/schema/line-chart-with-time-axis-schema.json'
).then(jsonify);

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

app.controller('MyController', function($scope) {
  $scope.dataSource = {
    data: null,
    caption: {
      text: 'Sales Analysis'
    },
    subcaption: {
      text: 'Grocery'
    },
    yAxis: [
      {
        plot: {
          value: 'Grocery Sales Value',
          type: 'line'
        },
        format: {
          prefix: '$'
        },
        title: 'Sale Value'
      }
    ]
  };

  Promise.all([dataFetch, schemaFetch]).then(res => {
    const data = res[0];
    const schema = res[1];
    const fusionTable = new FusionCharts.DataStore().createDataTable(
      data,
      schema
    );
    $scope.$apply(function() {
      $scope.dataSource.data = fusionTable;
    });
  });
});

Use a bundler like browserify to bundle the script
See the installation docs here

$ browserify script.js -o bundle.js

Again in your index.html

<html>
  <head>
    <!-- Include compiled bundle in script tag -->
    <script type="text/javascript" src="https://github.com/fusioncharts/angularjs-fusioncharts/raw/master/bundle.js"></script>
  </head>

  <body ng-app="myApp">
    <div ng-controller="MyController">
      <div
        fusioncharts
        width="600"
        height="400"
        type="timeseries"
        datasource-dt="dataSource">
        // When using TimeSeries pass your dataSource in "datasource-dt" attribute not in "datasource".
      </div>
    </div>
  </body>
</html>

Important note :- If the chart's datasource has an instance of dataStore like in case of timeseries then you must use the new datasource-dt attribute for passing the data in html

Special Note

If you want to support your application on IE(11 and below), then you need to take following steps:

Firstly

You have to update your angularjs-fusioncharts and fusioncharts modules to latest versions. For angularjs-fusioncharts install v5.0.1 and above; for fusioncharts install v3.13.3-sr.1 and above.

Secondly

In your template, modify your code like so,

<div
  fusioncharts
  width="600"
  height="400"
  type="ANY_CHART_TYPE"
  datasource-dt="dataSource"
>
  // Instead of passing data in datasouce, use datasource-dt.
</div>
