我下载了聚合物入门套件1.2.3版的中级 - 高级用户版本。然后我跑了
bower install a-dot
在polymer-starter-kit目录中。
然后我添加了
<script src="../bower_components/platform/platform.js"></script>
之前
<script src="bower_components/webcomponentsjs/webcomponents-lite.js"></script>
我还添加了
<paper-material elevation="1">
<a-dot dot="digraph {1 -> 1 -> 2; 2 -> 3; 2 -- 4; 2 -> 1 }"></a-dot>
</paper-material>
<section data-route="home">
</section>
根据我所看到的情况，我没有看到图表：
有没有人知道我错过了什么？
谢谢

答案 0 :(得分：0)
我找到了解决方案。它工作正常，但没有设置a-dot的宽度和高度。
这是解决方案：
<paper-material elevation="1">
<a-dot style="width:100%;height:300px;" dot="digraph {1 -> 1 -> 2; 2 -> 3; 2 -- 4; 2 -> 1 }"></a-dot>
</paper-material>
