无论如何在line chart使用中禁用插值chartjs？我只是红色整个文档,并没有找到任何关于这个.

升级到之后RC6,会发生以下错误:

zone.js:101 GET http://localhost/traceur 404 (Not Found)
zone.js:484 Unhandled Promise rejection: Error: XHR error (404 Not Found) loading http://localhost/traceur

更新我的项目后RC6发生以下错误:

Error: Typescript found the following errors:

  Object literal may only specify known properties, and 'directives' does not exist in type 'ComponentMetadataType'.

app.component.ts

import {NavbarComponent} from "./shared/navbar/navbar.component";
import {ROUTER_DIRECTIVES} from "@angular/router";

是否可以更新任何chart从ng2-charts动态？我知道还有其他类似的库angular2-highcharts,但我想用它来处理它ng2-charts.主要问题是如何chart在按钮点击后重绘？我可以调整窗口大小并更新数据,因此必须手动执行此操作.

我有以下问题:让我们假设我Component A有两个subcomponents Ar和Ad.Subcomponent Ar是递归创建的树,subcomponent Ad是在递归树(subcomponent Ar)中显示有关选择节点的详细信息的组件.如何将所选节点从子(子)组件Ar发送到Component Ad使用@Output？应该是@Output或其他什么？

app.component.html:

<tree [input]="fooTree" [output]="updateDetails($event)"></tree>
<tree-details [input]="input"></tree-details>

tree.component.html:

<tree [input]="fooTree.children"></tree>

树details.component.html

<div>{{input.name}}</div>
<div>{{input.id}}</div>

在这种情况下,我将只看到根树详细信息,如何从其他节点(递归创建之一)获取信息,何时选中？
