Create a Chart in Ember Using FusionCharts

Overview

The ember-fusioncharts component, provide bindings for FusionCharts JavaScript charting library. It lets you add interactive JavaScript charts and graphs to your web and mobile applications using EmberJS component.

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

Installation

To install FusionCharts and the ember-fusioncharts component via npm follow the steps below:

Step 1: Install fusioncharts core library

$ npm install fusioncharts --save

Step 2: Install ember-fusioncharts

You can install ember-fusioncharts component for any of the following CLI:

$ ember install ember-fusioncharts

That completes the installation of FusionCharts and the ember-fusioncharts component.

Create your first chart

Let's create a Column 2D chart using the ember-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 using ember-fusioncharts component, follow the steps below:

Step 1: In ember-cli-build.js file include the necessary files and add the dependency.

  • Import FusionCharts library to your ember-cli-build.js file

  • Import ember-fusioncharts to your ember-cli-build.js file

  • Import specific modules to your ember-cli-build.js file

  • Import the FusionCharts theme file to apply the style to the charts

If you need to use different assets in different environments, specify an object as the first parameter. That object's keys should be the environment name and the values should be the asset to use in that environment.

/* eslint-env node */
"use strict";

const EmberApp = require("ember-cli/lib/broccoli/ember-app");

module.exports = function(defaults) {
  let app = new EmberApp(defaults, {
    // Add options here
  });

  // Import fusioncharts library
  app.import("node_modules/fusioncharts/fusioncharts.js");
  app.import("node_modules/fusioncharts/fusioncharts.charts.js");
  app.import("node_modules/fusioncharts/themes/fusioncharts.theme.fusion.js");
  // Use `app.import` to import additional libraries/files
  return app.toTree();
};

To include specific chart types, individually add the following files using import:

  • 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

Step 2: Create Component and specify the chart data in chart-viewer.js file

  • Create a simple component (e.g. chart-viewer) to render your chart.

  • Add data to chart-viewer.js file

  • Set the chart width and height

  • 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 data source

$ ember g component chart-viewer
import Component from "@ember/component";

const 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"
  },
  // 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"
    }
  ]
}; // end of this.dataSource

export default Component.extend({
  title: "Ember FusionCharts Sample",
  width: 700,
  height: 400,
  type: "column2d",
  dataFormat: "json",
  dataSource: myDataSource
});

Step 3: Add data to chart-viewer.hbs

Add fusioncharts component to your chart-viewer.hbs template to render the chart:

<h1>{{ title }}</h1>
{{fusioncharts-xt width=width height=height type=type dataFormat=dataFormat
dataSource=dataSource }}

Step 4: Add data to application.hbs

Add chart-viewer component to your application.hbs template:

{{chart-viewer}} {{outlet}}

That's it! Your first chart using ember-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.
