本文介绍了NG2-图表无法绑定到“数据集"，因为它不是“画布"的已知属性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用NG2-Charts的基本示例( http://valor-software.com/ng2-charts/)

I am trying to use the basic example of NG2-Charts (http://valor-software.com/ng2-charts/)

我复制粘贴了HTML部分

I copy pasted the HTML part

  <div style="display: block">
    <canvas baseChart
        [datasets]="barChartData"
        [labels]="barChartLabels"
        [options]="barChartOptions"
        [legend]="barChartLegend"
        [chartType]="barChartType"
        (chartHover)="chartHovered($event)"
        (chartClick)="chartClicked($event)"></canvas>
  </div>

和TypeScript部分

and the TypeScript part

  private barChartOptions: any = {
    scaleShowVerticalLines: false,
    responsive: true
  };
  private barChartLabels: string[] = ['2006', '2007', '2008', '2009', '2010', '2011', '2012'];
  private barChartType: string = 'bar';
  private barChartLegend: boolean = true;

  private barChartData: any[] = [
    { data: [65, 59, 80, 81, 56, 55, 40], label: 'Series A' },
    { data: [28, 48, 40, 19, 86, 27, 90], label: 'Series B' }
  ];

  // events
  private chartClicked(e: any): void {
      console.log(e);
  }

  private chartHovered(e: any): void {
      console.log(e);
  }

我运行npm install ng2-charts --save，npm install chart.js --save和typings install dt~chart.js --save --global

我也在我的vendor.ts文件中导入了chart.js

I also imported chart.js in my vendor.ts file

import 'chart.js';

我的依赖项:

{
    "@angular/common": "^2.0.0",
    "@angular/compiler": "2.0.0",
    "@angular/core": "2.0.0",
    "@angular/forms": "2.0.0",
    "@angular/http": "2.0.0",

    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.11",
    "zone.js": "^0.6.23"
  }

这是错误

NG2-Charts网站上说我需要将其包含在HTML中

The NG2-Charts website says I need to include this in the HTML

<script src="node_modules/chart.js/src/chart.js"></script>

但是我认为这是不正确的，因为该声明如何在高效的缩小/内置应用中起作用?我还认为我的webpack import声明已经可以解决这个问题? 我四处搜寻，但遗憾的是在NG2图表上只找到了一些Angular 2 Beta版本的内容.

But I think thats not correct because how would that statement work in a productive minified / built app? I also thought my webpack import statement would already take care of that? I googled around but sadly only found stuff for some Angular 2 Beta version on NG2 Charts.

有人对如何解决这个问题有想法吗?

Does anyone has an idea on how to fix that?

推荐答案

尝试像这样在您的app.module.ts中导入ChartsModule-

Try importing ChartsModule in your app.module.ts like this-

import { ChartsModule } from 'ng2-charts/ng2-charts';

imports: [
   .....
   ChartsModule
   .....
]
