在Angular 5中制作饼图

Question

如何在Angular 5中制作饼图。我是硬编码数据（数据不是来自API），并希望在到期和批次的基础上制作饼图。以下是我的代码

component.html

<ng-container matColumnDef="expiration">
  <mat-header-cell *matHeaderCellDef> Expiration </mat-header-cell>
  <mat-cell *matCellDef="let csvdata"> {{csvdata.expiration}} </mat-cell>
</ng-container>

<ng-container matColumnDef="lotstatus">
  <mat-header-cell *matHeaderCellDef> Lot Status </mat-header-cell>
  <mat-cell *matCellDef="let csvdata"> {{csvdata.lotstatus}} </mat-cell>
</ng-container>

component.ts

const ELEMENT_DATA: Element[] = [
  { type: 'MEDIA', id: 'SAB', name: 'Sabour aud Dextros e Agar', location: 'SLAB', department: 'MICS', workstation: '', manufacturer: '', lotnumber: '2337515', opened: '28/7/17', closed: '', recieved: '', registration: '', expiration: '', lotstatus: 'A', norecieved: '1 Packs', units: '1 Packs', subunits: '0', test: '' },

Answer 1

我建议你使用D3js

你可以做很多图表。像PieChart

你可以在这里找到一个教程：Create a Pie Chart with Dynamic Data Using D3.js & Angular 2

Answer 2

我建议你看看chart.js。

我最近在Angular 6中使用它来渲染在点击时相互影响的饼图和条形图。我认为它易于使用，您可以在线找到答案，文档也很有帮助。

Answer 3

正如其他人提到的，您可以使用chart.js作为依赖项并根据需要生成饼图，

import { Chart } from 'chart.js';

就个人而言，我已经使用了带有角度和角度的chart.js，它的效果非常好。如果你想使用任何软件包，请使用ngx-charts，内部使用chart.js
