我制作了一个力导向图,我想更改包含的数据节点的形状,"entity":"company"
以便它们具有矩形形状,而没有这部分数据的另一个节点将像现在一样是圆形。
你可以在这里看到我只有圆形节点的工作示例:http: //jsfiddle.net/dzorz/uWtSk/
我尝试if else
在部分代码中添加带有语句的矩形,在其中我将形状附加到节点,如下所示:
function(d)
{
if (d.entity == "company")
{
node.append("rect")
.attr("class", function(d){ return "node type"+d.type})
.attr("width", 100)
.attr("height", 50)
.call(force.drag);
}
else
{
node.append("circle")
.attr("class", function(d){ return "node type"+d.type})
.attr("r", function(d) { return radius(d.value) || 10 })
//.style("fill", function(d) { return fill(d.type); })
.call(force.drag);
}
}
但是后来我在任何节点上都没有得到任何形状。
什么是正确的设置方法?
整个代码如下所示: 脚本:
var data = {"nodes":[
{"name":"Action 4", "type":5, "slug": "", "value":265000},
{"name":"Action 5", "type":6, "slug": "", "value":23000},

{"name":"Action 1", "type":2, "slug": "",},
{"name":"Action 2", "type":3, "slug": "",},
{"name":"Bing", "type":1, "slug": "www.bing.com", "entity":"company"},
