Я создал диаграммы детализации, используя angular2-highcharts, включив детализацию модуля.

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { NgModule, Component }    from '@angular/core';
import { BrowserModule }          from '@angular/platform-browser';
import { ChartModule }            from 'angular2-highcharts'; 

@Component({
    selector: 'my-app',
    styles: [`
      chart {
        display: block;
      }
    `],
    template: `<chart [options]="options"></chart>`
})
class AppComponent {
    constructor() { 
        this.options = {
            chart: {
        type: 'column'
    },
    title: {
        text: 'Browser market shares. January, 2015 to May, 2015'
    },
    subtitle: {
        text: 'Click the columns to view versions. Source: <a href="http://netmarketshare.com">netmarketshare.com</a>.'
