我正在尝试将 dc.js 图表库集成到我的 angular 项目中。我遵循了 SO 上的链接，该链接指示如何将 dc.js 图表与 angular2+ dc.js charts with Angular2+ 集成.我运行以下行来安装所需的所有软件包。npm i --save dc @types/dc crossfilter2 d3 @types/d3我有一个基本的 Angular 项目。我的 Angular 版本是 7，我还附上了我的 app.component.html , app.component.ts , app.module.ts , package.json和我的 angular.json下面的文件。
app.component.html <div #nameOfDiv></div> app.component.ts
import * as d3 from "d3";
import * as dc from "dc";
import * as crossfilter from "crossfilter2";
import { Dimension } from "crossfilter2";
interface Data {
letter: string;
frequency: number;
}
@Component({
selector: "app-root",
templateUrl: "./app.component.html",
styleUrls: ["./app.component.css"]
})
export class AppComponent {
@ViewChild("nameOfDiv", { static: false }) chartDiv: ElementRef;
title = "DC";
private chart: dc.PieChart;
private ndx: any = crossfilter<Data>([
{ letter: "B", frequency: 2 },
{ letter: "A", frequency: 10 }
]);
paintChart(): void {
this.chart = dc.pieChart("#pie");
let dim = this.ndx.dimension((d: any) => d.letter);
let group = dim.group().reduceCount();
this.chart
.width(200)
.height(200)
.dimension(dim)
.group(group);
dc.renderAll();
}
}

我该如何解决这个问题？
最佳答案
我也遇到了同样的问题，以下方法对我有用。
import * as crossfilter from 'crossfilter2/crossfilter';
crossFilterObj = crossfilter(data);
关于angular - crossfilter2__WEBPACK_IMPORTED_MODULE_3__ 不是函数，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59925481/
