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 vue-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:

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';

//Include the chart type
import Charts from 'fusioncharts/fusioncharts.charts';

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

// Register VueFusionCharts component
Vue.use(VueFusionCharts);

// register VueFusionCharts component
Vue.use(VueFusionCharts, FusionCharts, Charts, FusionTheme)

var app = new Vue({
    el: '#app',
    data: {
        width: '700',
        height: '400',
        type: 'column2d',
        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"
            }]
        }
    }
});

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"
    ref="fc"
    ></fusioncharts>
</div>

The above chart has been rendered using the following steps:

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

  2. Register vue-fusioncharts component.

  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 a fusioncharts directive in a template.
