我是角度5实际上是全角2概念的新手。 我在visual studio 2017中创建了具有角度5和.net核心的新项目。 我正在尝试使用d3和ng2-nvd3。我在npm中添加了包。我尝试运行页面时遇到错误。
以下是错误。
NodeInvocationException: Template parse errors: Can't bind to 'options' since it isn't a known property of 'nvd3'. ("<div>
<nvd3 [ERROR ->][options]="options" [data]="data"></nvd3>
</div>

")

App.shared.module.ts如下所示。
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule } from '@angular/router';
import { AppComponent } from './components/app/app.component';
import { NavMenuComponent } from './components/navmenu/navmenu.component';
import { HomeComponent } from './components/home/home.component';
import { FetchDataComponent } from './components/fetchdata/fetchdata.component';
import { CounterComponent } from './components/counter/counter.component';
import { NvD3Module } from "ng2-nvd3";
// d3 and nvd3 should be included somewhere
import 'd3';
import 'nvd3';
@NgModule({
declarations: [
AppComponent,
NavMenuComponent,
CounterComponent,
FetchDataComponent,
NvD3Module,
HomeComponent
],
imports: [
CommonModule,
HttpModule,
FormsModule,
RouterModule.forRoot([
{ path: '', redirectTo: 'home', pathMatch: 'full' },
{ path: 'home', component: HomeComponent },
{ path: 'counter', component: CounterComponent },
{ path: 'fetch-data', component: FetchDataComponent },
{ path: '**', redirectTo: 'home' }
])
]
})
export class AppModuleShared {
}
</pre>
home.component.ts如下图所示我试图添加图表
import { Component, OnInit } from '@angular/core';
import { NvD3Module } from "ng2-nvd3";
import 'd3';
import 'nvd3';
@Component({
selector: 'home',
templateUrl: './home.component.html'
})
export class HomeComponent implements OnInit {
ngOnInit(): void {
}
options: any;
data: any;
constructor() {
this.options = {
chart: {
type: 'pieChart',
height: 500,
x: function (d) {
return d.key;
},
y: function (d) {
return d.y;
},
showLabels: true,
duration: 500,
labelThreshold: 0.01,
labelSunbeamLayout: true,
legend: {
margin: {
top: 5,
right: 35,
bottom: 5,
left: 0
}
}
}
};
this.data = [
{
key: "P60-1",
y: 500
},
{
key: "P60-2",
y: 445
},
{
key: "P40",
y: 225
},
{
key: "P73",
y: 127
},
{
key: "P71",
y: 128
}
];
}
}
App.server.module.ts如下所示
import { NgModule } from '@angular/core';
import { ServerModule } from '@angular/platform-server';
import { AppModuleShared } from './app.shared.module';
import { AppComponent } from './components/app/app.component';
@NgModule({
bootstrap: [ AppComponent ],
imports: [
ServerModule,
AppModuleShared
]
})
export class AppModule {
}
和home.component.html看起来像这样
<div>
<nvd3 [options]="options" [data]="data"></nvd3>
</div>
我做错了什么？
答案 0 :(得分：0)
您需要将NvD3Module添加到导入列表而不是声明。
@NgModule({
imports: [ // import Angular's modules
...
NvD3Module
...
],
})
