我正在尝试使用xrange类型的HighCharts:
import { ChartModule } from 'angular2-highcharts';
import * as highcharts from 'highcharts';
import { HighchartsStatic } from '../../../../node_modules/angular2-highcharts/dist/HighchartsService';
export function highchartsFactory() {
const hc = require('highcharts');
const dd = require('highcharts/modules/xrange');
dd(hc);
return hc;
}
@NgModule({
imports: [
/* case 1 */
ChartModule
// in this case the code compiles but I get Error 17 in console
/* case 2 */
/* ChartModule.forRoot(require('highcharts'), require('highcharts/modules/xrange')) */
// in this case the code doesn't compiles with the error:
// "Error encountered resolving symbol values statically.
// Calling function 'ChartModule', function calls are not supported."
],
providers: [
{
provide: HighchartsStatic,
useValue: highcharts,
useFactory: highchartsFactory
}
})
在两种情况下,我都无法创建图表。有人告诉我,第一种情况是更好的方法,我想朝这个方向继续。
我看到许多使用此方法的帖子,没有一个提及此错误。

我建议您使用像example这样的官方highcharts npm软件包,但是您想使用angular2-highcharts。
使用以下方式更新您的应用模块
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';
import { ChartModule } from 'angular2-highcharts';
import { HighchartsStatic } from 'angular2-highcharts/dist/HighchartsService';
import Highcharts from 'highcharts';
import Exporting from 'highcharts/modules/exporting';
import xrange from "highcharts/modules/xrange";
xrange(Highcharts);
Exporting(Highcharts);
export function highchartsFactory() {
return Highcharts;
}
@NgModule({
imports: [ BrowserModule, FormsModule , ChartModule],
declarations: [ AppComponent, HelloComponent ],
providers: [
{ provide: HighchartsStatic, useFactory: highchartsFactory } // add as factory to your providers
],
bootstrap: [ AppComponent ]
})
export class AppModule { }
