Create a Chart in AngularJS Using FusionCharts

FusionCharts is a JavaScript charting library that enables you to create interactive charts, gauges, maps and dashboards in JavaScript. We have built a simple and lightweight Angularjs directive which provides bindings for FusionCharts. The angularjs-fusioncharts directive allows you to easily add rich and interactive charts to any Angularjs project.

In this page, we'll see how to install FusionCharts and render a chart using the angularjs-fusionCharts directive.

Installation

Install FusionCharts and the angularjs-fusioncharts directive using any of the following methods:

To install fusioncharts and the angularjs-fusioncharts directive via npm follow the steps below:
1. Install angularjs core library

    $ npm install angular
2. Install angularjs-fusioncharts

    $ npm install angularjs-fusioncharts
2. Install the fusioncharts package

    $ npm install fusioncharts
To install the FusionCharts package and the angularjs-fusioncharts component follow the steps below:

</head>

That completes the installation of FusionCharts and the angularjs-fusioncharts directive.

Create your first chart

Let's create a Column 2D chart using the angularjs-fusioncharts component showing the "Countries With Most Oil Reserves".

FusionCharts Suite has 95+ chart types for you to explore. Find the complete list of chart types here.

The Column 2D chart is shown below:

Chart data

The data to render the above chart is shown in the table below:

Country No. of Oil Reserves
Venezuela 290K
Saudi 260K
Canada 180K
Iran 140K
Russia 115K
UAE 100K
US 30K
China 30K

FusionCharts accepts data in JSON format. Following code is the JSON representation of the above table with the required attributes to render the above chart.

{
    // Chart Configuration
    "chart": {
        "caption": "Countries With Most Oil Reserves [2017-18]",
        "subCaption": "In MMbbl = One Million barrels",
        "xAxisName": "Country",
        "yAxisName": "Reserves (MMbbl)",
        "numberSuffix": "K",
        "theme": "fusion",
    },
    // Chart Data
    "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"
    }]
}

Different types of charts in FusionCharts expect different JSON formats, based on their grouping. Explore different JSON formats, for example, single-series,multi-series, combination charts.

In the above JSON data:

  • Create the chart object to define the elements of the chart.

  • Set the caption and subcaption of the chart.

  • Set the value of xAxisName attribute to Country(first column of the table).

  • Set the value of yAxisName attribute to Reserves(second column of the table).

  • In the data array, create objects for each row and specify the label attribute to represent the Country. For example, Venezuela.

  • Similarly, specify the value attribute to set the value of Oil Reserves in respective countries. For example, 290K for Venezuela.

  • Set the numberSuffix attribute to set the unit of the values.

  • Set the theme attribute to apply the predefines themes to the chart.

Both the chart object and the data array contain a set of key-value pairs known as attributes. These attributes are used to set the functional and cosmetic properties of the chart.

Now that you have the data in JSON format, let's see how to render the chart.

Render the chart

To render the chart, follow the steps below:

  1. Include angularjs using require.

  2. Include the fusioncharts library.

  3. Include angularjs-fusioncharts directive.

  4. Include ng-fusioncharts as a dependency in the application. Call angular.module() to add the dependency.

  5. Include the chart type.

  6. Include the FusionCharts theme file to apply style to the charts.

  7. Add the chart and the theme as dependencies to the core.

  8. Store the chart configurations in a variable (myApp).

  9. Add the <div> with an fc-chart directive in your HTML, assuming that it is inside a controller named MyController. In the <div>:

    • Set the chart type as column2d. Each chart type is represented with a unique chart alias. For Column 2D chart, the alias is column2d. Find the complete list of chart types with their respective alias here.
    • Set the width and height (in pixels).
    • Embed the json data as the value of the dataSource.

The consolidated code is shown below:


//  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');

// Require Fusion theme
var FusionTheme = require('fusioncharts/themes/fusioncharts.theme.fusion');

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

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

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

myApp.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",
            "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"
            }
        ]
    };
}]);
// Render
chartInstance.render()
Create an HTML template as shown below:

<body ng-app="myApp">
    <div ng-controller="MyController">
        <div
        fusioncharts
        width="700"
        height="400"
        type="column2d"
        datasource="{{myDataSource}}">
        </div>
    </div>
</body>
To include the specific chart types, individually add the following files using require
  • PowerCharts - fusioncharts/fusioncharts.powercharts
  • Widgets - fusioncharts/fusioncharts.widgets
  • Gantt - fusioncharts/fusioncharts.gantt
  • Treemap - fusioncharts/fusioncharts.treemap
  • Zoomscatter - fusioncharts/fusioncharts.zoomscatter
  • Zoomline - fusioncharts/fusioncharts.zoomline
  • Overlapped Bar - fusioncharts/fusioncharts.overlappedbar2d
  • Overlapped Column - fusioncharts/fusioncharts.overlappedcolumn2d

That's it! Your first chart using angularjs-fusioncharts is ready.

Problem rendering the chart?

In case there is an error, and you are unable to see the chart, check for the following:

  • If you are getting a JavaScript error on your page, check your browser console for the exact error and fix accordingly. If you're unable to solve it, click here to get in touch with our support team.

  • If the chart does not show up at all, but there are no JavaScript errors, check if the FusionCharts Suite XT JavaScript library has loaded correctly. You can use developer tools within your browser to see if fusioncharts.js was loaded.

  • If you get a Loading Data or Error in loading data message, check whether your JSON data structure is correct, or there are conflicts related to quotation marks in your code.
