具有多层级瀑布图

下面是一个具有多层级的 SanKey 图示例。

我们之前已在 Google Charts 配置语法 章节中学习用于绘制图表的配置。现在，让我们看一个具有多层级 SanKey 图的示例。

配置

我们使用 Sankey 类来显示具有多层级的 SanKey 图。

type = 'Sankey';

示例

app.component.ts

import { Component } from '@angular/core';
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   title = '';
   type = 'Sankey';
   data = [
      ["Brazil","Portugal",5],
      ["Brazil","France",1],
      ["Brazil","Spain",1],
      ["Brazil","England",1],
      ["Canada","Portugal",1],
      ["Canada","France",5],
      ["Canada","England",1],
      ["Mexico","Portugal",1], 
      ["Mexico","France",1],
      ["Mexico","Spain",5],
      ["Mexico","England",1], 
      ["USA","Portugal",1], 
      ["USA","France",1],
      ["USA","Spain",1],
      ["USA","England",5],
      ["Portugal","Angola",2], 
      ["Portugal","Senagal",1],
      ["Portugal","Morocco",1],
      ["Portugal","South Africa",3]
   ];
   columnNames = ['From', 'To','Weight'];
   options = {       
   };
   width = 550;
   height = 400;
}
