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 vue-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.

FusionCharts will load here..

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

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

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.

In this step, we will create an instance of the chart type as column2d, set the width and height (in pixels or %), and finally specify the JSON data for the chart as a string.

The code to render a chart is given below:

//Including Vue
import Vue from 'vue';

// Include the vue-fusioncharts component
import VueFusionCharts from 'vue-fusioncharts';

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

//Include the chart type
import Column2D from 'fusioncharts/viz/column2d'

// register VueFusionCharts component
Vue.use(VueFusionCharts, FusionCharts, Column2D)

var app = new Vue({
    el: '#app',
    data: {
        type: 'column2d',
        width: '700',
        height: '400',
        dataFormat: 'jsonurl',
        dataSource: 'https://static.fusioncharts.com/sample/oilReserves.json' // url of datasource
    }
});

Now, use the fusioncharts directive in a template. The HTML template is given below:

<div id="app">
    <fusioncharts
    :type="type"
    :width="width"
    :height="height"
    :dataFormat="dataFormat"
    :dataSource="dataSource"
    ></fusioncharts>
</div>

The above chart has been rendered using the following steps:

Include the necessary libraries and components using import. For example, vue-fusioncharts, fusioncharts, etc.
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.
To set the datasource using URL:
- Set the value of the dataFormat as jsonurl.
- Set the static URL to dataSource to render the above chart.
Created a fusioncharts directive in a template.

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.
