自定义 Sankey 图表

以下是一个自定义 Sankey 图表的示例。

我们已经在 Google 图表配置语法 章节中了解了用于绘制图表的配置。现在，让我们看看一个自定义 Sankey 图表的示例。

配置

我们使用 **Sankey** 选项来自定义 Sankey 图表。

options = {
   sankey: {  
      link:{
         color:{
            stroke:'black',
            strokeWidth:1
         }
      }    
   } 
};

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]
   ];
   columnNames = ['From', 'To','Weight'];
   options = {
      sankey: {  
         link:{
            color:{
               stroke:'black',
               strokeWidth:1
            }
         }    
      } 
   };
   width = 550;
   height = 400;
}

结果

验证结果。
