Question

我正在尝试动态地将自定义颜色应用于边缘并更新sigmajs中的图形画布和webgl渲染器工作正常，但svg渲染器不起作用。它采用边缘颜色的默认值。

这是图书馆的链接：https://github.com/jacomyal/sigma.js

如果需要额外配置，有人可以指出我吗？

我的代码将是这样的：

$.each(s.graph.edges(), function(index, edge) {
  edge.color = '#f00';
});

我正在使用forceAtlas2插件来进行布局：https://github.com/jacomyal/sigma.js/tree/master/plugins/sigma.layout.forceAtlas2

此颜色更改适用于canvas和webgl，但不适用于svg。我需要svg才能工作，因为画布分辨率低，webgl不支持弯曲边缘。欢迎任何其他帮助。

Answer 1

您使用的是sigmajs主代码还是最后一个版本？

好的愚蠢问题，1.0.3上没有SVG渲染。

我已尝试使用此代码，并且正在使用我的Firefox：http://jsfiddle.net/annavester/Zd6uX/
