在力向图中高亮显示节点及其邻居节点

问题描述

限时删除！！

我已经使用D3.JS库

在mouseover上，我要突出显示一个节点及其邻居节点，然后淡出所有其他节点.

On mouseover what I would like to do is to highlight a node and its neighbour node and fade away all other nodes.

在mouseout事件上，我想按原样重设图形.

On mouseout event I want to reset the graph like the way it is.

我已尝试将以下代码用于突出显示部分，但无法正常工作:

I have tried the following code for the highlight part but its not working:

    .on("mouseover", function(d) {

d3.select(this).select("circle").style("stroke-width", 6);
var nodeNeighbors = graph.links.filter(function(link) {

 return link.source.index === d.index || link.target.index === d.index;})
                        .map(function(link) {

 return link.source.index === d.index ? link.target.index : link.source.index; });

以下是我的受力导向图的链接

推荐答案

这几乎是，有关详细信息，请参见此处.

This is almost a complete copy and paste from this question, see there for the explanation of the details.

我唯一要做的更改是通过过渡淡入/淡入节点/链接，并在两个方向上向用于确定邻居的数据结构添加连接.完整的演示此处.

The only things I have changed is to fade the nodes/links out/in with a transition and added connections in both directions to the data structure that is used to determine the neighbours. Complete demo here.
