Create a Gauge in React using FusionCharts

Overview

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 React component which provides bindings for FusionCharts. The react-fusioncharts component allows you to easily add rich and interactive charts to any React project.

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

Create your first gauge

Gauges are powerful tools that can showcase information using a radial or linear scale to display data.

To start with, we'll build a simple angular gauge showcasing Nordstorm's Customer Satisfaction Score as shown below.

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

The angular gauge is shown below:

FusionCharts will load here..

The thresholds for the above sample have been defined using the following range:

Range Color Hex Code
0-50 Red #F2726F
50-75 Yellow #FFC533
75-100 Green #62B58F

So, any score less than 50 is bad and is red. Any score between 50 and 75 is average and is yellow. Any score above 75 means good and are green.

Convert tabular data into JSON format

Now that you have the tabular data ready, it's time to convert it into JSON format, as FusionCharts accepts data in JSON or XML format. In this example, we will use the JSON format, as shown below:

{
    // Chart Configuration
    "chart": {
        "caption": "Nordstorm's Customer Satisfaction Score for 2017",
        "lowerLimit": "0",
        "upperLimit": "100",
        "showValue": "1",
        "numberSuffix": "%",
        "theme": "fusion",
        "showToolTip": "0"
    },
    // Chart Data
    "colorRange": {
        "color": [{
            "minValue": "0",
            "maxValue": "50",
            "code": "#F2726F"
        }, {
            "minValue": "50",
            "maxValue": "75",
            "code": "#FFC533"
        }, {
            "minValue": "75",
            "maxValue": "100",
            "code": "#62B58F"
        }]
    },
    "dials": {
        "dial": [{
            "value": "81"
        }]
    }
}

In the above JSON:

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

  • Create the colorRange array to set the color associated with the specific range of values.

  • Specify minValue and maxValue within the color array under the colorRange array.

  • Specify the hex code of the color within the color array.

  • Create the dials object to represent the customer satisfaction score.

  • Create the dial object under dials object to set the value of the dial in an array.

The chart object and the respective arrays contain a set of key-value pairs known as attributes. These attributes are used to set the functional and cosmetic properties of the gauge.

Now that you have converted the tabular data to JSON format, let's learn how to render the gauge.

Render the gauge

To render the gauge, follow the steps below:

  1. Include react

  2. Include react-fusioncharts

  3. Include the fusioncharts library

  4. Include gauge type.

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

  6. Add the gauge and the theme as a dependency to the core.

  7. Store the chart configurations as a JSON object. In this JSON object:

    • Set the gauge type as angulargauge. Each chart type is represented with a unique chart alias. For Angular Gauge, the alias is angulargauge. Find the complete list of gauge types with their respective alias here.

    • Set the width and height (in pixels).

    • Set the dataFormat as json.

    • Embed the json data as the value of the dataSource.

  8. Create the DOM element and pass the react-fusioncharts component directly to the ReactDOM.render() method.

The consolidated code is shown below:

// Step 1 - Including react
import React from 'react';
import ReactDOM from 'react-dom';

// Step 2 - Including the react-fusioncharts component
import ReactFC from 'react-fusioncharts';

// Step 3 - Including the fusioncharts library
import FusionCharts from 'fusioncharts';

// Step 4 - Including the chart type
import Widgets from 'fusioncharts/fusioncharts.widgets';

// Step 5 - Including the theme as fusion
import FusionTheme from 'fusioncharts/themes/fusioncharts.theme.fusion';

// Step 6 - Adding the chart as dependency to the core fusioncharts
ReactFC.fcRoot(FusionCharts, Widgets, FusionTheme);

// Step 7 - Creating the JSON object to store the chart configurations
const chartConfigs = {
    type: 'angulargauge', // The gauge type
    width: '450', // Width of the gauge
    height: '250', // Height of the gauge
    dataFormat: 'json', // Data type
    dataSource: {
    // Chart Configuration
      "chart": {
          "caption": "Nordstorm's Customer Satisfaction Score for 2017",
          "lowerLimit": "0",
          "upperLimit": "100",
          "showValue": "1",
          "numberSuffix": "%",
          "theme": "fusion",
          "showToolTip": "0"
      },
      // Chart Data
      "colorRange": {
          "color": [{
              "minValue": "0",
              "maxValue": "50",
              "code": "#F2726F"
          }, {
              "minValue": "50",
              "maxValue": "75",
              "code": "#FFC533"
          }, {
              "minValue": "75",
              "maxValue": "100",
              "code": "#62B58F"
          }]
      },
      "dials": {
          "dial": [{
              "value": "81"
          }]
      }
  }
};

// Step 8 - Creating the DOM element to pass the react-fusioncharts component 
class App extends React.Component {
  render() {
     return (
     <ReactFC
        {...chartConfigs}/>
     );
  }
}

export default App

That's it! Your first gauge using react-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.
