Setting Data Source Using URL

FusionCharts lets you pass the complete JSON/XML chart data as a static string to the dataSource attribute. Alternatively, you can also save the chart data in a .json or .xml file and then pass the relative URL of this file as value to the dataSource attribute.

The only difference between the two methods is the value that is passed to the dataFormat attribute. For the first method, the dataFormat attribute takes json or xml as values, depending on the chart data. For the second method, the values will be jsonurl and xmlurl.

This article explains how you can set the chart data using the URL of the corresponding file using react-fusioncharts component.

Load data using JSON as URL

Let's build the same revenue chart which we built in the first example using JSON, and use a .json file as the data source.

{
    "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"
        }
    ]
}

The data for this chart is represented in the table below:

The JSON representation for the above table looks as shown below:

{
    // 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"
    }]
}

Copy this into a file, name it oilReserves.json, and store it in the same folder as your HTML page.

If you are using multilingual characters in your JSON, make sure that you save the JSON data with UTF-8 encoding.

The full code of the above sample is given below:

//Including react
import React, { Component } from 'react';

//Including the react-fusioncharts component
import ReactDOM from 'react-dom';

//Including the fusioncharts library
import FusionCharts from 'fusioncharts/core';

//Including the chart type
import Column2D from 'fusioncharts/viz/column2d';

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

//Adding the chart as dependency to the core fusioncharts
ReactFC.fcRoot(FusionCharts, Column2D, FusionTheme);

//Creating the JSON object to store the chart configurations

const chartConfigs = {
  type: 'column2d',
  width: 700,
  height: 400,
  dataFormat: 'jsonurl',
  dataSource: 'https://static.fusioncharts.com/sample/oilReserves.json', // url of datasource
};

class Chart extends Component {
  render () {
    return (
      <ReactFC {...chartConfigs} />
    )
  }
}

ReactDOM.render(
  <Chart />,
  document.getElementById('root'),
);

The above chart has been rendered using the following steps:

1. Include the necessary libraries and components using import. For example, react-fusioncharts, fusioncharts, etc.

2. Store the chart configuration in a JSON object. In the JSON object:

   • Set the chart type as column2d. Find the complete list of chart types with their respective alias here .
   • Set the width and height of the chart in pixels.
   • Set the dataFormat as JSON.
   • Set the value of exportEnabled attribute to 1, which enables the export feature of the chart.

3. To set the datasource using URL:

   • Set the value of the dataFormat to jsonurl.
   • Set the static URL to dataSource to render the above chart.

4. Create a DOM element and the react-fusioncharts component is passed directly to the ReactDOM.render() method.

When rendering your charts locally (without a web server, even if on the localhost), you will not be able to load data from XML or JSON files present on your hard-drive. This is due to security restrictions enforced by most modern browsers.

Load data using XML as URL

The XML representation for the above chart looks as shown below:

<chart caption='Countries With Most Oil Reserves [2017-18] ' subcaption='In MMbbl = One Million barrels ' xaxisname='Country ' yaxisname='Reserves (MMbbl) ' numberprefix='K ' theme='fusion '>
    <set label='Venezuela ' value='290 ' />
    <set label='Saudi ' value='260 ' />
    <set label='Canada ' value='180 ' />
    <set label='Iran ' value='140 ' />
    <set label='Russia ' value='115 ' />
    <set label='UAE ' value='100 ' />
    <set label='US ' value='30 ' />
    <set label='China ' value='30 ' />
</chart>

Copy this into a file called oilReserves.xml and store it in the same folder as your HTML page.

If you are using multilingual characters in your XML, make sure you save the XML data with UTF-8 encoding.

//Including react
import React, { Component } from 'react';

//Including the chart type

//Including the theme as fusion

//Adding the chart as dependency to the core fusioncharts
ReactFC.fcRoot(FusionCharts, Column2D, FusionTheme);

//Creating the JSON object to store the chart configurations

const chartConfigs = {
  type: 'column2d',
  width: 700,
  height: 400,
  dataFormat: 'xmlurl',
  dataSource: 'https://static.fusioncharts.com/sample/oilReserves.xml', // url of datasource
};

//Your react component
class Chart extends Component {
  render () {
    return (
      <ReactFC {...chartConfigs} />
    )
  }
}

ReactDOM.render(
  <Chart />,
  document.getElementById('root'),
);
