Angular 角度及；图表

我第一次尝试在我的演示中应用图表，我已经完成了下面的示例，但它没有显示任何内容，HTML结果是一个空白页面

从'@angular/core'导入{Component，AfterViewInit}；
从“角度”导入*作为角度；
@组成部分({
选择器：“ea启动器”，
templateUrl:“./starter.component.html”
})
导出类StarterComponent实现AfterViewInit{
标题：字符串；
字幕：字符串；
构造函数（）{
angular.module（“angular2demo”，[“chart.js”]）.controller（“DoughnutCtrl”，函数（$scope）{
$scope.labels=[“下载销售”、“店内销售”、“邮购销售”]；
$scope.data=[300500100]；
});         
}
ngAfterViewInit（）{
}
}

日志结果：

Angular is running in the development mode. Call enableProdMode() to enable the production mode.  core.es5.js:2925

您将angularjs和angularjs混合在一起，为了使用angularjs生成图表，您可以使用一些库，其中ng2图表是一种流行的图表

您需要在

NgModule

中导入

图表模块

import { ChartsModule } from 'ng2-charts';

<div id="chart-container">
    <canvas #myCanvas id="canvas" baseChart [chartType]="chartType" [datasets]="chartData" [labels]="chartLabels" [colors]="chartColors" [options]="chartOptions"></canvas>
</div>

this.chartData = [{
      data: [3, 1, 4, 2, 5],
      label: 'Anthracnose',
      fill: false
    }];
    this.chartLabels = ['Jan', 'Feb', 'Mar', 'Apr', 'May'];
    this.chartColors = [{
      backgroundColor: 'rgba(0, 0, 0, 0.2)',
         borderColor: 'rgba(0, 0, 0, 1)'
    }];
    this.chartOptions = {
      scales: {
        yAxes: [{
          ticks: {
            beginAtZero: true,
            stepSize: 1
          }
        }]
      }
    }
  };

以及您的
组件.html

import { ChartsModule } from 'ng2-charts';

<div id="chart-container">
    <canvas #myCanvas id="canvas" baseChart [chartType]="chartType" [datasets]="chartData" [labels]="chartLabels" [colors]="chartColors" [options]="chartOptions"></canvas>

    }];
    this.chartLabels = ['Jan', 'Feb', 'Mar', 'Apr', 'May'];
    this.chartColors = [{
      backgroundColor: 'rgba(0, 0, 0, 0.2)',
         borderColor: 'rgba(0, 0, 0, 1)'

您似乎随机混合了角度和角度，这不太可能导致成功。你在控制台中看到任何错误吗？你正在混合angular和AngularJS检查如何在angular中使用图表我已经用日志结果更新了记录单你似乎随机混合AngularJS和AngularJS，这不太可能成功。您在控制台中看到任何错误吗？您正在混合角度和角度JS检查如何在角度中使用图表我已经用日志结果更新了记录单
