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 angular-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"
        }
    ]
}COPY

Setup the Main Module

In this step, we will setup the main module to create the Column 2D chart. The code is given below:

// Setup needed in app.module.ts
import { NgModule,  enableProdMode } from '@angular/core'
import { AppComponent } from './app.component';
import { BrowserModule } from '@angular/platform-browser';
import { FusionChartsModule } from 'angular-fusioncharts';

// Load FusionCharts
import * as FusionCharts from 'fusioncharts';
// Load Charts module
import * as Charts from 'fusioncharts/fusioncharts.charts';
// Load fusion theme
import * as Fusion from 'fusioncharts/themes/fusioncharts.theme.fusion'

// Add dependencies to FusionChartsModule
FusionChartsModule.fcRoot(FusionCharts, Charts, Fusion)

@NgModule({
    declarations: [
        AppComponent,
    ],
    imports: [
        BrowserModule,
        FusionChartsModule,
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule {}COPY

In the above code:

1. Include the necessary libraries and componentsusing import. For example, angular-fusioncharts, fusioncharts, etc.

2. Load FusionCharts, chart module and the fusion theme.

3. Add dependencies to FusionChartsModule.

The <fusioncharts></fusioncharts> component is available to be used by any component your app. We will render our first chart in the main app.component.

Add data to app.component.ts

Add the following code to app.component.ts:

// in app.component.ts
import {
    Component
} from '@angular/core';

@Component({
    selector: 'app',
    templateUrl: 'app.component.html'
})

export class AppComponent {{
    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"
            }
        ]
    }
}COPY

In the above code:

1. Add the JSON data within the AppComponent class.

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

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

Add data to app.component.html

Add the following code to app.component.html:

<!-- in app.component.html -->
<fusioncharts
    width={{width}}
    height={{height}}
    type={{type}}
    dataFormat={{dataFormat}}
    [dataSource]=dataSource >
</fusioncharts>COPY

In the above code, create the fusioncharts directive in a template.
