Angular Highcharts:基本折线图(Basic Line Chart)

  折线图用于绘制基于线/样条线的图表。在本节中,我们将讨论不同类型的基于线和样条线的图表。

基本折线图

  我们已经在“配置语法”一章中看到了用于绘制图表的配置。现在让我们考虑下面的例子来进一步理解一个基本的折线图。

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: "spline"
      },
      title: {
         text: "Monthly Average Temperature"
      },
      subtitle: {
         text: "Source: WorldClimate.com"
      },
      xAxis:{
         categories:["Jan", "Feb", "Mar", "Apr", "May", "Jun",
            "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]
      },
      yAxis: {          
         title:{
            text:"Temperature °C"
         } 
      },
      tooltip: {
         valueSuffix:" °C"
      },
      series: [{
         name: 'Tokyo',
         data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2,26.5, 23.3, 18.3, 13.9, 9.6]
      },
      {
         name: 'New York',
         data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8,24.1, 20.1, 14.1, 8.6, 2.5]
      },
      {
         name: 'Berlin',
         data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
      },
      {
         name: 'London',
         data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
      }]
   };
}
