折線圖，柱狀圖，餅狀圖。。。都在這里。https://www.djamware.com/post/598953f880aca768e4d2b12b/creating-beautiful-charts-easily-using-ionic-3-and-angular-4

1，首先確保項目能啟動，沒有問題。然后：

1.1 安裝 Angular 2 Charts and Charts.js

npm install ng2-charts --save
npm install chart.js --save、

1.2 導包

在你當前頁面（需要畫這些圖的文件夾），打開***.model.ts文件，

import { ChartsModule } from 'ng2-charts';
        
imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp),
    ChartsModule
],

這是所需要安裝的全部東西。

2. 編寫HTML和TS文件

2.1，MTHL中

    <ion-content padding>
      <div class="row">
        <div class="col-md-6">
          <div style="display: block;">
          <canvas baseChart width="300" height="400"
                      [datasets]="lineChartData"
                      [labels]="lineChartLabels"
                      [options]="lineChartOptions"
                      [colors]="lineChartColors"
                      [legend]="lineChartLegend"
                      [chartType]="lineChartType"
                      (chartHover)="chartHovered($event)"
                      (chartClick)="chartClicked($event)"></canvas>
          </div>
        </div>
      </div>
    </ion-content>

2.2 TS 中

    public lineChartData:Array<any> = [
      {data: [65, 59, 80, 81, 56, 55, 40], label: 'Series A'},
      {data: [28, 48, 40, 19, 86, 27, 90], label: 'Series B'},
      {data: [18, 48, 77, 9, 100, 27, 40], label: 'Series C'}
    ];
    public lineChartLabels:Array<any> = ['January', 'February', 'March', 'April', 'May', 'June', 'July'];
    public lineChartOptions:any = {
      responsive: true
    };
    public lineChartColors:Array<any> = [
      { // grey
        backgroundColor: 'rgba(148,159,177,0.2)',
        borderColor: 'rgba(148,159,177,1)',
        pointBackgroundColor: 'rgba(148,159,177,1)',
        pointBorderColor: '#fff',
        pointHoverBackgroundColor: '#fff',
        pointHoverBorderColor: 'rgba(148,159,177,0.8)'
      },
      { // dark grey
        backgroundColor: 'rgba(77,83,96,0.2)',
        borderColor: 'rgba(77,83,96,1)',
        pointBackgroundColor: 'rgba(77,83,96,1)',
        pointBorderColor: '#fff',
        pointHoverBackgroundColor: '#fff',
        pointHoverBorderColor: 'rgba(77,83,96,1)'
      },
      { // grey
        backgroundColor: 'rgba(148,159,177,0.2)',
        borderColor: 'rgba(148,159,177,1)',
        pointBackgroundColor: 'rgba(148,159,177,1)',
        pointBorderColor: '#fff',
        pointHoverBackgroundColor: '#fff',
        pointHoverBorderColor: 'rgba(148,159,177,0.8)'
      }
    ];
    public lineChartLegend:boolean = true;
    public lineChartType:string = 'line';
    
    public randomize():void {
      let _lineChartData:Array<any> = new Array(this.lineChartData.length);
      for (let i = 0; i < this.lineChartData.length; i++) {
        _lineChartData[i] = {data: new Array(this.lineChartData[i].data.length), label: this.lineChartData[i].label};
        for (let j = 0; j < this.lineChartData[i].data.length; j++) {
          _lineChartData[i].data[j] = Math.floor((Math.random() * 100) + 1);
        }
      }
      this.lineChartData = _lineChartData;
    }
    
    // events
    public chartClicked(e:any):void {
      console.log(e);
    }
    
    public chartHovered(e:any):void {
      console.log(e);
    }

好了，這使用的是假數據，啟動項目，看看是不是如下這樣的一個折線圖。
