Adding Special Characters

FusionCharts offers multiple options to format numbers on the chart. You can configure number prefixes and suffixes, decimal places, and scale numbers based on a predefined scale. This article focuses on how you customize the prefix and suffix of the numbers on the chart using jquery-fusioncharts component.

To customize the prefix and suffix of the numbers on the chart, use the following attributes:

• Specify the prefix for all the values on the chart using the numberPrefix attribute. Note that the value of this attribute works only if you don't specifically mention the values of the yNumberPrefix and xNumberPrefix attributes.

• Specify the prefix for all the Y-axis values on the chart using the yNumberPrefix attribute. If you don't mention this attribute, the chart will inherit the default value from the numberPrefix attribute.

• Specify the prefix for all the X-axis values on the chart using the xNumberPrefix attribute. If you don't mention this attribute, the chart will inherit the default value from the numberPrefix attribute.

• Specify the suffix for all the values on the chart using the numberSuffix attribute. Note that the value of this attribute works only if you don't specifically mention the values of the yNumberSuffix and xNumberSuffix attributes.

• Specify the suffix for all the Y-axis values on the chart using the yNumberSuffix attribute. If you don't mention this attribute, the chart will inherit the default value from the numberSuffix attribute.

• Specify the suffix for all the X-axis values on the chart using the xNumberSuffix attribute. If you don't mention this attribute, the chart will inherit the default value from the numberSuffix attribute.

A chart configured to customize the prefix of the numbers on the chart is shown below:

{
    "chart": {
        "caption": "Monthly revenue for last year",
        "subCaption": "Harry's SuperMart",
        "xAxisName": "Month",
        "yAxisName": "Revenues (In USD)",
        "numberPrefix": "$",
        "theme": "fusion"
    },
    "data": [
        {
            "label": "Jan",
            "value": "420000"
        },
        {
            "label": "Feb",
            "value": "810000"
        },
        {
            "label": "Mar",
            "value": "720000"
        },
        {
            "label": "Apr",
            "value": "550000"
        },
        {
            "label": "May",
            "value": "910000"
        },
        {
            "label": "Jun",
            "value": "510000"
        },
        {
            "label": "Jul",
            "value": "680000"
        },
        {
            "label": "Aug",
            "value": "620000"
        },
        {
            "label": "Sep",
            "value": "610000"
        },
        {
            "label": "Oct",
            "value": "490000"
        },
        {
            "label": "Nov",
            "value": "900000"
        },
        {
            "label": "Dec",
            "value": "730000"
        }
    ]
}

The code to render a chart using require is given below:

// Include fusioncharts
var FusionCharts = require('fusioncharts');

// Include chart modules
var Charts = require('fusioncharts/fusioncharts.charts');

// Include the theme file
var FusionTheme = require('fusioncharts/themes/fusioncharts.theme.fusion');

var $ = require('jquery');
var jQueryFusionCharts = require('jquery-fusioncharts');

// Resolve Charts as dependency for FusionCharts
Charts(FusionCharts); 

// Resolve Fusion theme as dependency for FusionCharts
FusionTheme(FusionCharts); 

// Resolve FusionCharts as dependency for jqueryFusionCharts
jQueryFusionCharts(FusionCharts); 

$('document').ready(function () {
    $('#chart-container').insertFusionCharts({
    id: 'change-chart',
    type: 'column2d',
    renderAt: 'chart-container',
    width: '700',
    height: '400',
    dataFormat: 'json',
        dataSource: {
            "chart": {
                "caption": "Monthly revenue for last year",
                "subCaption": "Harry's SuperMart",
                "xAxisName": "Month",
                "yAxisName": "Revenues (In USD)",
                "numberPrefix": "$",
                "theme": "fusion"
            },
            "data": [{
                "label": "Jan",
                "value": "420000"
            }, {
                "label": "Feb",
                "value": "810000"
            }, {
                "label": "Mar",
                "value": "720000"
            }, {
                "label": "Apr",
                "value": "550000"
            }, {
                "label": "May",
                "value": "910000"
            }, {
                "label": "Jun",
                "value": "510000"
            }, {
                "label": "Jul",
                "value": "680000"
            }, {
                "label": "Aug",
                "value": "620000"
            }, {
                "label": "Sep",
                "value": "610000"
            }, {
                "label": "Oct",
                "value": "490000"
            }, {
                "label": "Nov",
                "value": "900000"
            }, {
                "label": "Dec",
                "value": "730000"
            }]
        }
    });
});

The HTML template of the above sample is shown below:

<div id="chart-container">
    FusionCharts will render here
</div>

The above chart has been rendered using the following steps:

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

2. Resolve charts as dependency for fusioncharts, theme file and jquery-fusioncharts.

3. 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.
   • Embed the json data as the value of dataSource.

4. In the dataSource object, add numberPrefix attribute in chart object. Set the numberPrefix to $.

5. Create an HTML template to render the chart.
