【问题描述】:
我尝试将 ChartJS 添加到 Angular2,但它一直说 Chart 未定义。我安装了 ChartJS 类型并引用了它。我还将 chartjs 脚本添加到 index.html 文件中。我做错了什么?
/// <reference path="../../website/typings/main/ambient/chart/index.d.ts" />
import {Directive, ElementRef, Renderer, Input} from 'angular2/core';
@Directive({
selector: '[chart]'
})
export class ChartDirective {
constructor(el: ElementRef, renderer: Renderer) {
//el.nativeElement.style.backgroundColor = 'yellow';
var data = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [
{
label: "My First dataset",
fillColor: "rgba(220,220,220,0.2)",
strokeColor: "rgba(220,220,220,1)",
pointColor: "rgba(220,220,220,1)",
pointStrokeColor: "#fff",
pointHighlightFill: "#fff",
pointHighlightStroke: "rgba(220,220,220,1)",
data: [65, 59, 80, 81, 56, 55, 40]
},
{
label: "My Second dataset",
fillColor: "rgba(151,187,205,0.2)",
strokeColor: "rgba(151,187,205,1)",
pointColor: "rgba(151,187,205,1)",
pointStrokeColor: "#fff",
pointHighlightFill: "#fff",
pointHighlightStroke: "rgba(151,187,205,1)",
data: [28, 48, 40, 19, 86, 27, 90]
}
]
};
var ctx: any = el.nativeElement.getContext("2d");
var lineChart = new Chart(ctx);
////var lineChartOptions = areaChartOptions;
////lineChartOptions.datasetFill = false;
lineChart.Line(data);
}
}
更新:
这是我的 index.html 文件:
