Angular Google Charts – Combination Chart ”; Previous Next Combination chart helps in rendering each series as a different marker type from the following list: line, area, bars, candlesticks, and stepped area. To assign a default marker type for series, use the seriesType property. Series property is to be used to specify properties of each series individually. Following is an example of a Column Chart showing differences. We have already seen the configurations used to draw a chart in Google Charts Configuration Syntax chapter. Now, let us see an example of a Column Chart showing differences. Configurations We”ve used ComboChart class to show a Combination Chart. type=”ComboChart”; Example app.component.ts import { Component } from ”@angular/core”; @Component({ selector: ”app-root”, templateUrl: ”./app.component.html”, styleUrls: [”./app.component.css”] }) export class AppComponent { title = ”Fruits distribution”; type = ”ComboChart”; data = [ [“Apples”, 3, 2, 2.5], [“Oranges”,2, 3, 2.5], [“Pears”, 1, 5, 3], [“Bananas”, 3, 9, 6], [“Plums”, 4, 2, 3] ]; columnNames = [”Fruits”, ”Jane”,”Jone”,”Average”]; options = { hAxis: { title: ”Person” }, vAxis:{ title: ”Fruits” }, seriesType: ”bars”, series: {2: {type: ”line”}} }; width = 550; height = 400; } Result Verify the result.

Angular Google Charts – Configuration Syntax ”; Previous Next 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.
