Javascript Angular.js自定义指令和d3.js

由于stackoverflow的存在，使angular.js指令与d3结合使用并不难。但是我不能让那些箭起作用。代码取自M.Bostock的一个示例。 我只是想把它写进指令，但失败了。当我检查DOM时，可以看到箭头，但它们不会出现。有人有线索吗

我根据您提供的内容创建了一个plnkr，它工作正常-您对AngularJS和D3的引用是否正常

首先，感谢您的快速回复。我知道样式问题只是没有提供任何css。该图在我的系统上也运行良好。这只是一个大问题，图形不会呈现博斯托克在原稿中看到的箭头。问题一定与angular.js指令生命周期有关？@MunichAngularMan为什么你认为指令生命周期有问题，你会去他的Plnkr吗？除非你用的是像IE这样糟糕的浏览器，否则它看起来很棒。我用的是chrome。看看我第一篇文章中的新Plunkr，告诉我你看到了那些该死的箭头。我认为这可能与线条路径上的marker end属性有关。在我的plnkr示例中，URL与Bostock示例中的URL不同。你知道吗，我认为指令链接代码实际上发生了变化，因为当我添加CSS时，它使行变细，但是没有箭头。我复制并粘贴了他示例中的链接函数，我更改了我的链接函数，因此希望它与原始链接相同，并将其修复。我刚刚看了你最近的plnkr，我可以看到你有细线，但没有箭头，所以它可能是值得更新的指令链接功能和比较，看看有什么不同。
