如何在Angular上使用Highchart?

问题描述 投票:-1回答:1

我想在我的角度上制作一个带有Highchart的图表,但由于在Highchart的官方网站上缺乏关于Angular中Highchart使用的信息,我不得不使用它。

这是queue-dashboard.component.ts上的高级图书馆:

import { Component, OnInit, ViewEncapsulation } from '@angular/core';
import { CountryunitService } from '../../countryunit.service';
import * as Highcharts from 'highcharts';
import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http';
import { map } from 'lodash';

这是ngOnInit() queue-dashboard.component.ts中的内容

ngOnInit() {

  var chart = Highcharts.chart('container', {

    title: {
      text: 'Chart.update'
    },

    subtitle: {
      text: 'Plain'
    },

    xAxis: {
      categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },

    series: [{
      type: 'column',
      colorByPoint: true,
      data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4],
      showInLegend: false
    }]

  });

如果要调用此队列中的图表 - dashboard.component.html,我该怎么办?

<div eds-tile class="xl-6" style="height: 350px">
<eds-tile-title>Count of Ticket ID by CU ID</eds-tile-title>
<!-- Highchart On This -->
</div>
javascript angular highcharts highcharts-ng

有多种方法可以使用HTML呈现图表。将尝试解释其中的一些

1.我们可以通过在图表配置对象中指定元素名称来渲染元素上的图表。因此,假设您要在HTML文件中提到的div上呈现图表。

<div eds-tile class="xl-6" style="height: 350px">
<eds-tile-title>Count of Ticket ID by CU ID</eds-tile-title>
<div id="chartContainer"></div>
<!-- Highchart On This -->
</div>

您可以通过在元素上呈现来配置图表对象

import { Component, OnInit, ViewEncapsulation } from '@angular/core';
import { CountryunitService } from '../../countryunit.service';
import * as Highcharts from 'highcharts';
import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http';
import { map } from 'lodash';

导出类YourComponentName实现OnInit {

setTimeout( ()=>{
  this.Highcharts.chart({
   chart: {
      type: 'column',
      renderTo:'chartContainer',
  },
  title: {
      text: 'Chart.update'
  },

  subtitle: {
      text: 'Plain'
  },

  xAxis: {
      categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
  },

  series: [{
      type: 'column',
      colorByPoint: true,
      data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4],
      showInLegend: false
  }]

})},3000);
  1. 另一种方法是您可以动态创建图表配置对象并绑定到您尝试绘制的容器内。 this.chartConfig = { title: { text: 'Chart.update' }, subtitle: { text: 'Plain' }, xAxis: { categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'] }, series: [{ type: 'column', colorByPoint: true, data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4], showInLegend: false }] }

在您的HTMl中,您可以动态绑定图表(指令)

 <div eds-tile class="xl-6" style="height: 350px">
<eds-tile-title>Count of Ticket ID by CU ID</eds-tile-title>
<div id="chartContainer">
<chart [options]="chartConfig"></chart>
 </div>
<!-- Highchart On This -->
</div>

可能有可能没有取高度和宽度的高图的css。要添加,你可以在你的组件css / scss中添加这个css。

chart {
 width: 100% !important;
 margin: 0 auto;
 display: block;
}

.highcharts-root {
  width: 100% !important;
  display: block;
  } 

 .highcharts-container {
   width: 100% !important;
  }
