javascript - Highcharts - 无法在角度 6 中调整 onclick 按钮的大小

问题描述

我有一个角度为 6 的 Highcharts，它工作正常，但是每当我单击一个按钮时，我想通过添加类来调整其大小/增加它的宽度。div 增加了，但图表没有增加。我尝试了 reflow 和 window resize 属性，但它没有已解决。任何人都可以帮助我。这是下面的代码。

app.component.html

<button (click)="change()">change</button>
<div [ngClass]="{'old': toggle, 'new': !toggle}" class="old" id="chart1"></div>

app.component.ts

declare var require: any;
import { Component } from '@angular/core';
import * as Highcharts from 'highcharts';
import * as Exporting from 'highcharts/modules/exporting';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements ResultPageInterface{
  title = 'projectchart';
  toggle:boolean = true;
  change(){
    this.toggle = !this.toggle;
  }
  ngOnInit(){
  this.chartFunc('chart1');
  }
chartFunc(chartId){
  Highcharts.chart(chartId,{
   chart: {
         type: "spline"
      },
      title: {
         text: "Monthly Average Temperature"
      },

      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]
         }
      ]
   });
}

}

解决方案

看; 调整图表 div 容器的大小并不总是调整图表本身的大小。

试试我的解决方案：

  • 将图表声明为组件变量：

    chartElement: Highcharts.Chart;

  • 使用图表模块创建图表。

    import { chart } from 'highcharts'; ... ngOnInit() { // this.chart = chart(chartId, {chart: {}...}) }

  • 使用this.chart.redraw()函数调整图表大小。
