Create a Map in Angular using FusionCharts

Overview

FusionCharts is a JavaScript charting library that enables you to create interactive charts, gauges, maps and dashboards in JavaScript. We have built a simple and lightweight Angular component which provides bindings for FusionCharts. The angular-fusioncharts component allows you to easily add rich and interactive charts to any Angular project.

In this page, we'll see how to install FusionCharts and render a map using the angular-fusionCharts component.

Since, Angular2 and onward do not support the direct <script> tags, angular-fusioncharts can only be used via npm.

Installation

To install FusionCharts and the angular-fusioncharts component via npm follow the steps below:

Step 1: Install angular-fusioncharts

$ npm install angular-fusioncharts --save

Step 2: Install fusioncharts core library

$ npm install fusioncharts --save

That completes the installation of FusionCharts and the angular-fusioncharts component.

Create you First map

In this section, we will create a visualization using the World Map showing the average annual population growth.

FusionCharts will load here..

Map data

The data for the above map is represented in the table below:

State Entity Name Value
North America NA 82
South America SA 2.04
Asia AS 1.78
Europe EU 40
Africa AF 2.58
Australia AU 1.30

In the above table, the column Entity Name represents the geographical entities represented in the map, whose full names are given in the State column.

FusionCharts accepts data in JSON format in which the above entities are denoted by the id key in the data object.

For any map visualization, it is important to provide the correct value for the id keys. For example, if you want to denote Africa, the value for the corresponding id must be AF and not AFR.

We have a detailed Map Specification Sheets for all the maps that can be rendered using FusionCharts, where you can find the correct id of the maps you want to create.

Following code is the JSON representation of the above table with the required attributes to render the above map.

{
    // Map Configuration
    "chart": {
            "caption": "Average Annual Population Growth",
            "subcaption": " 1955-2015",
            "numbersuffix": "%",
            "includevalueinlabels": "1",
            "labelsepchar": ": ",
            "entityFillHoverColor": "#FFF9C4",
            "theme": "fusion"
    },
    // Aesthetics; ranges synced with the slider
    "colorrange": {
        "minvalue": "0",
        "code": "#FFE0B2",
        "gradient": "1",
        "color": [{
            "minvalue": "0.5",
            "maxvalue": "1.0",
            "color": "#FFD74D"
        }, {
            "minvalue": "1.0",
            "maxvalue": "2.0",
            "color": "#FB8C00"
        }, {
            "minvalue": "2.0",
            "maxvalue": "3.0",
            "color": "#E65100"
        }]
    },
    // Source data as JSON --> id represents countries of world.
    "data": [{
        "id": "NA",
        "value": ".82",
        "showLabel": "1"
    }, {
        "id": "SA",
        "value": "2.04",
        "showLabel": "1"
    }, {
        "id": "AS",
        "value": "1.78",
        "showLabel": "1"
    }, {
        "id": "EU",
        "value": ".40",
        "showLabel": "1"
    }, {
        "id": "AF",
        "value": "2.58",
        "showLabel": "1"
    }, {
        "id": "AU",
        "value": "1.30",
        "showLabel": "1"
    }]
}

In the above JSON data:

  • Create the chart object to define the elements of the map.

  • Create the colorRange array to set the color associated with the specific range of values.

  • Specify minValue and maxValue within the color array under the colorRange array.

  • Create the data array to define the id of the continents and their corresponding values along with configurations. For example, the first object under data array contains the id and value of North America as NA and .82 respectively.

The chart object and the respective arrays contain a set of key-value pairs known as attributes. These attributes are used to set the functional and cosmetic properties of the map.

Now that you have the data in JSON format, let's learn how to render the map.

Render the map

To render the chart follow the steps below:

Step 1: In app.module.ts include the necessary files and add the dependency.

  • Import angular-fusioncharts in the root @NgModule.

  • Import FusionCharts library in the root @NgModule.

  • Import the map renderer file.

  • Import the map type.

  • Import the FusionCharts theme file to apply the style to the charts.

  • Pass the fusioncharts library, map module, and the FusionTheme.

The consolidated code is shown below:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';

// Import angular-fusioncharts
import { FusionChartsModule } from 'angular-fusioncharts';

// Import FusionCharts library and chart modules
import * as FusionCharts from 'fusioncharts';
import *  as FusionMaps from 'fusioncharts/fusioncharts.maps';
import * as World from 'fusionmaps/maps/fusioncharts.world';

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

// Pass the fusioncharts library and chart modules
FusionChartsModule.fcRoot(FusionCharts, FusionMaps, World, FusionTheme);

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

Step 2: Add data to the angular app.component.ts

Set the JSON data within the AppComponent class as shown below:

The code below is same for Angular older and latest versions.

import {Component} from '@angular/core';
@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
})
export class AppComponent {
    dataSource: Object;
    constructor() {
        this.dataSource = {
            "chart": {
                "caption": "Average Annual Population Growth",
                "subcaption": " 1955-2015",
                "numbersuffix": "%",
                "includevalueinlabels": "1",
                "labelsepchar": ": ",
                "entityFillHoverColor": "#FFF9C4",
                "theme": "fusion"
            },
            // Aesthetics; ranges synced with the slider
            "colorrange": {
                "minvalue": "0",
                "code": "#FFE0B2",
                "gradient": "1",
                "color": [{
                    "minvalue": "0.5",
                    "maxvalue": "1.0",
                    "color": "#FFD74D"
                }, {
                    "minvalue": "1.0",
                    "maxvalue": "2.0",
                    "color": "#FB8C00"
                }, {
                    "minvalue": "2.0",
                    "maxvalue": "3.0",
                    "color": "#E65100"
                }]
            },
            // Source data as JSON --> id represents countries of world.
            "data": [{
                "id": "NA",
                "value": ".82",
                "showLabel": "1"
            }, {
                "id": "SA",
                "value": "2.04",
                "showLabel": "1"
            }, {
                "id": "AS",
                "value": "1.78",
                "showLabel": "1"
            }, {
                "id": "EU",
                "value": ".40",
                "showLabel": "1"
            }, {
                "id": "AF",
                "value": "2.58",
                "showLabel": "1"
            }, {
                "id": "AU",
                "value": "1.30",
                "showLabel": "1"
            }]
        }
    }
}

Step 3: Now use fusioncharts component in app.component.html

Create the map container and set the following:

  • Map width and height.

  • The map type as world. Each map type is represented with a unique alias. For World map, the alias is world. Find the complete list of map types with their respective alias here.

  • The data source.

<h1>
  {{title}}
</h1>
<fusioncharts
    width="800"
    height="550"
    type="world"
    [dataSource]="dataSource">
</fusioncharts>

That's it! Your first map using angular-fusioncharts is ready.

Render other maps

To reduce the size of the package FusionCharts comes with only two maps, i.e., the World map and the USA map. However, FusionCharts provide 1600+ maps for you to explore. Download the map files separately if you want to save them locally.

Let's create a map of California to show the "Web visits for a particular month" as shown below:

FusionCharts will load here..

To render the above map, first install fusionmaps package which contains all the map definition files as shown below:

$ npm install fusionmaps

After installing fusionmaps package, follow the steps to render the map:

Step 1: In app.module.ts include the necessary files and add the dependency.

  • Import angular-fusioncharts in the root @NgModule.

  • Import FusionCharts library in the root @NgModule.

  • Import the map renderer file.

  • Import the map type.

  • Import the FusionCharts theme file to apply the style to the charts.

  • Pass the fusioncharts library, map module, and the FusionTheme.

The consolidated code is shown below:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';

// Import angular-fusioncharts
import { FusionChartsModule } from 'angular-fusioncharts';

// Import FusionCharts library and chart modules
import * as FusionCharts from 'fusioncharts';
import *  as FusionMaps from 'fusioncharts/fusioncharts.maps';
import * as California from 'fusionmaps/maps/fusioncharts.california';

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

// Pass the fusioncharts library and chart modules
FusionChartsModule.fcRoot(FusionCharts, FusionMaps, California, FusionTheme);

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

Step 2: Add data to the angular app.component.ts

Set the JSON data within the AppComponent class as shown below:

The code below is same for Angular older and latest versions.

import {Component} from '@angular/core';
@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
})
export class AppComponent {
    dataSource: Object;
    constructor() {
        this.dataSource = {
            "chart": {
                "animation": "0",
                "showbevel": "0",
                "usehovercolor": "1",
                "canvasbordercolor": "FFFFFF",
                "bordercolor": "FFFFFF",
                "showlegend": "1",
                "legendposition": "BOTTOM",
                "legendborderalpha": "0",
                "legendbordercolor": "ffffff",
                "legendallowdrag": "0",
                "legendshadow": "0",
                "caption": "Website Visits for the month of March 2018",
                "connectorcolor": "000000",
                "fillalpha": "80",
                "hovercolor": "CCCCCC",
                "showborder": 0,
                "theme": "fusion"
            },
            "colorrange": {
                "minvalue": "0",
                "startlabel": "Low",
                "endlabel": "High",
                "code": "e44a00",
                "gradient": "1",
                "color": [{"maxvalue": "2500", "code": "f8bd19"}, {"maxvalue": "5000", "code": "6baa01"}]

            },
            "data": [{"id":"001","value":2834},{"id":"003","value":3182},{"id":"005","value":3280},{"id":"007","value":911},{"id":"009","value":292},{"id":"011","value":530},{"id":"013","value":2515},{"id":"015","value":728},{"id":"017","value":1974},{"id":"019","value":848},{"id":"021","value":3278},{"id":"023","value":4463},{"id":"025","value":1198},{"id":"027","value":378},{"id":"029","value":2610},{"id":"031","value":1200},{"id":"033","value":3820},{"id":"035","value":940},{"id":"037","value":3416},{"id":"039","value":4004},{"id":"041","value":1604},{"id":"043","value":4011},{"id":"045","value":3203},{"id":"047","value":3775},{"id":"049","value":2721},{"id":"051","value":3417},{"id":"053","value":1530},{"id":"055","value":412},{"id":"057","value":3434},{"id":"059","value":1670},{"id":"061","value":1274},{"id":"063","value":4339},{"id":"065","value":2073},{"id":"067","value":1018},{"id":"069","value":3967},{"id":"071","value":3401},{"id":"073","value":3307},{"id":"075","value":1938},{"id":"077","value":489},{"id":"079","value":3207},{"id":"081","value":2295},{"id":"083","value":2747},{"id":"085","value":1114},{"id":"087","value":3400},{"id":"089","value":784},{"id":"091","value":1673},{"id":"093","value":4274},{"id":"095","value":4509},{"id":"097","value":3862},{"id":"099","value":1356},{"id":"101","value":4126},{"id":"103","value":1314},{"id":"105","value":1807},{"id":"107","value":4026},{"id":"109","value":3456},{"id":"111","value":1393},{"id":"113","value":1500},{"id":"115","value":2218}]
        }
    }
}

Step 3: Now use fusioncharts component in app.component.html.

Create the chart container and set the following:

  • Chart width and height.

  • The map type as california. Each map type is represented with a unique map alias. For California map, the alias is california. Find the complete list of map types with their respective alias here.

  • The data source.

<h1>
  {{title}}
</h1>
<fusioncharts
    width="800"
    height="550"
    type="california"
    [dataSource]="dataSource">
</fusioncharts>

That's it! The California map is ready.

Problem rendering the chart?

In case there is an error, and you are unable to see the chart, check for the following:

  • If you are getting a JavaScript error on your page, check your browser console for the exact error and fix accordingly. If you're unable to solve it, click here to get in touch with our support team.

  • If the chart does not show up at all, but there are no JavaScript errors, check if the FusionCharts Suite XT JavaScript library has loaded correctly. You can use developer tools within your browser to see if fusioncharts.js was loaded.

  • If you get a Loading Data or Error in loading data message, check whether your JSON data structure is correct, or there are conflicts related to quotation marks in your code.
