Angular Google Charts - Configuration Syntax

Quiz

In this chapter, we will showcase the configuration required to draw a chart using the Google Chart API in Angular.

Step 1 - Create Angular Application

Follow the following steps to update the Angular application we created in Angular 6 - Project Setup chapter −

Step	Description
1	Create a project with a name googleChartsApp as explained in the Angular 6 - Project Setup chapter.
2	Modify app.module.ts, app.component.ts and app.component.html as explained below. Keep rest of the files unchanged.
3	Compile and run the application to verify the result of the implemented logic.

Following is the content of the modified module descriptor app.module.ts.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { GoogleChartsModule } from 'angular-google-charts';
@NgModule({
   declarations: [
      AppComponent   
   ],
   imports: [
      BrowserModule,GoogleChartsModule
   ],
   providers: [], bootstrap: [AppComponent]
})
export class AppModule { }

Following is the content of the modified HTML host file app.component.html.

<google-chart #chart
   [title]="title"
   [type]="type"
   [data]="data"
   [columnNames]="columnNames"
   [options]="options"
   [width]="width"
   [height]="height">
</google-chart>

We'll see the updated app.component.ts in the end after understanding configurations.

Step 2 - Use Configurations

Set Title

title = 'Browser market shares at a specific website, 2014';

Set Chart Type

type='PieChart';

data

Configure the data to be displayed on the chart.

data = [
   ['Firefox', 45.0],
   ['IE', 26.8],
   ['Chrome', 12.8],
   ['Safari', 8.5],
   ['Opera', 6.2],
   ['Others', 0.7] 
];

column names

Configure the column names to be displayed.

columnNames = ['Browser', 'Percentage'];

options

Configure the other options.

options = {
   colors: ['#e0440e', '#e6693e', '#ec8f6e', '#f3b49f', '#f6c7b6'], is3D: true
};

Example

Consider the following example to further understand the Configuration Syntax −

app.component.ts

import { Component } from '@angular/core';
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   title = 'Browser market shares at a specific website, 2014';
   type = 'PieChart';
   data = [
      ['Firefox', 45.0],
      ['IE', 26.8],
      ['Chrome', 12.8],
      ['Safari', 8.5],
      ['Opera', 6.2],
      ['Others', 0.7] 
   ];
   columnNames = ['Browser', 'Percentage'];
   options = {    
   };
   width = 550;
   height = 400;
}

Result

Verify the result.
