Angular Highcharts - 基础柱形图

以下是柱形图示例。

我们在 Highcharts 配置语法 一章中已经了解了用于绘制图表的配置。现在，让我们看一个基础柱形图的示例。我们还将了解其他配置。我们在图表中更改了 type 属性。

图表

将图表类型配置为基于“柱形”。chart.type 确定了图表的系列类型。此处，默认值为“折线”。

var chart = {
   type: 'column'
};

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: 'column'
      },
      title: {
         text: 'Monthly Average Rainfall'
      },
      subtitle:{
         text: 'Source: WorldClimate.com' 
      },
      xAxis:{
         categories: ['Jan','Feb','Mar','Apr','May','Jun','Jul',
         'Aug','Sep','Oct','Nov','Dec'],
         crosshair: true        
      },     
      yAxis : {
         min: 0,
         title: {
            text: 'Rainfall (mm)'         
         }      
      },
      tooltip : {
         headerFormat: '<span style = "font-size:10px">{point.key}</span><table>',
         pointFormat: '<tr><td style = "color:{series.color};padding:0">{series.name}: </td>' +
            '<td style = "padding:0"><b>{point.y:.1f} mm</b></td></tr>', footerFormat: '</table>', shared: true, useHTML: true
      },
      plotOptions : {
         column: {
            pointPadding: 0.2,
            borderWidth: 0
         }
      },
      series: [{
         name: 'Tokyo',
         data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6,
            148.5, 216.4, 194.1, 95.6, 54.4]
      }, 
      {
         name: 'New York',
         data: [83.6, 78.8, 98.5, 93.4, 106.0, 84.5, 105.0, 104.3,
            91.2, 83.5, 106.6, 92.3]
      }, 
      {
         name: 'London',
         data: [48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6,
            52.4, 65.2, 59.3, 51.2]
      }, 
      {
         name: 'Berlin',
         data: [42.4, 33.2, 34.5, 39.7, 52.6, 75.5, 57.4, 60.4,
            47.6, 39.1, 46.8, 51.1]
      }]
   };
}
