【问题描述】:
我在定位图表和更改气泡图中圆圈的颜色时遇到了一些问题。我需要通过消耗一些 json 内容来绘制一个包裹在 angular2 组件中的气泡图。我在指定空间/区域内定位图表时遇到了一些问题。
请参阅应用程序布局的快照。在基于一些用户点击事件的应用程序中,气泡图应该加载到正下方,但目前它是在页面下方加载方式,即在整个页面布局下方。此气泡图配置了 angular2 中的路由,预计将加载到指定的 router-outlet 标记中,但在
之外加载注意: 1. D3.js 用于绘制气泡图,封装在 angular2 组件中。 2. 我尝试减小图表组件的宽度和高度,但仍然没有渲染到想要的位置。
应在其中呈现图表的 HTML
<div class="container" style="overflow:scroll; height:100%; width:100%;">
<h2>Redis Administration</h2>
<ul class="nav nav-tabs">
<li class="active"><a data-toggle="tab" href="#ExtractorQueue" [routerLink]="['./']">ExtractorQueue</a></li>
<li><a data-toggle="tab" href="#Extractor" [routerLink]="['Extractor']">Extractor</a></li>
<li><a data-toggle="tab" href="#Schedule" [routerLink]="['Schedule']">Schedule</a></li>
<li><a data-toggle="tab" href="#CacheVisualization" [routerLink]="['CacheVisualization']">Cache Visualization</a></li>
</ul>
<div class="tab-content">
<router-outlet></router-outlet>
</div>
</div>
D3 封装在 angular2 组件代码中

【问题讨论】:
-
似乎图表是在 Angular2 根元素之外绘制为 SVG。您的代码未显示您如何集成 D3。
