从'@ angular / core'导入{NgModule,ViewChild,ElementRef};
从'@ angular / platform-b​​rowser'导入{BrowserModule};
从'@ angular / core'导入{Component};
导入*为'highcharts / highstock'的高级图表;
从'@ angular / http'导入{Jsonp,JsonpModule};

@ViewChild(container,{read:ElementRef})container:ElementRef;

构造函数(jsonp:Jsonp){
jsonp.request('https://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json& callscribe = JSONP_CALLBACK')。subscribe(res => {


Highcharts.stockChart(this.container.nativeElement,{

console.log('click clickd');

},{
键入:'ytd',
text:'YTD'
},{

},{
type:'all',
text:'All1'
}]
},
图表:{
zoomType:'x'
},
series:[{

data:res.json(),
tooltip :{
valueDecimals:2
}
}],
xAxis:{
events:{
afterSetExtremes:(e)=> {
// console.log(e);
// this.button = e.rangeSelectorButton.count;


$ b},
})
})
}
}


I want to access highstock rangeSelector button event inside my angular component.I am using the angular2-highcharts package to use the highcharts library. Tried to access it using the (afterSetExtremes) binding but without any success. The code is here. Please help.

Thanks!!

Check TypeScript highcharts version installation and implementation below.

stackblitz Demo

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { NgModule, ViewChild, ElementRef } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { Component } from '@angular/core';
import * as Highcharts from 'highcharts/highstock';
import { Jsonp, JsonpModule } from '@angular/http';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],

})
export class AppComponent {
  name = 'Angular 5 Highstock';
  @ViewChild("container", { read: ElementRef }) container: ElementRef;

  constructor(jsonp: Jsonp) {
    jsonp.request('https://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=JSONP_CALLBACK').subscribe(res => {


      Highcharts.stockChart(this.container.nativeElement, {
        rangeSelector: {
          buttons: [{
            type: 'month',
            count: 1,
            text: '1m',
            events: {
              click: function (e) {
                console.log('button clickd');
              }
            }
          }, {
            type: 'month',
            count: 3,
            text: '3m'
          }, {
            type: 'month',
            count: 6,
            text: '6m'
          }, {

          data: res.json(),
          tooltip: {
            valueDecimals: 2
          }

        xAxis: {
          events: {
            afterSetExtremes: (e) => {
              // console.log(e);
              // this.button = e.rangeSelectorButton.count;
