Angular Highcharts - 基本面积图

我们已经在 Highcharts 配置语法 章节中看到了用于绘制此图表的配置。 现在让我们考虑以下示例以进一步理解基本面积图。

示例

app.component.ts

import { Component } from '@angular/core';
import * as Highcharts from 'highcharts';
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   highcharts = Highcharts;
   chartOptions = {   
      chart: {
         type: 'area'
      },
      title: {
         text: '一周平均水果消耗量'
      },
      subtitle : {
         style: {
            position: 'absolute',
            right: '0px',
            bottom: '10px'
         }
      },
      legend : {
         layout: 'vertical',
         align: 'left',
         verticalAlign: 'top',
         x: -150,
         y: 100,
         floating: true,
         borderWidth: 1,
         backgroundColor: (
            Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'
      },
      xAxis:{
         categories: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'] 
      },
      yAxis : {
         title: {
            text: 'Number of units'
         },
         labels: {
            formatter: function () {
               return this.value;
            }
         },
         min:0
      },
      tooltip : {
         formatter: function () {
            return '<b>' + this.series.name + '</b><br/>' +
               this.x + ': ' + this.y;
         }
      },
      plotOptions : {
         area: {
            fillOpacity: 0.5 
         }
      },
      credits:{
         enabled: false
      },
      series: [
         {
            name: 'John',
            data: [3, 4, 3, 5, 4, 10, 12]
         }, 
         {
            name: 'Jane',
            data: [1, 3, 4, 3, 3, 5, 4]
         }
      ]
   };
}

结果

验证结果。
