vis.js 大节点以分层模式重叠
vis.js 中的节点是否可以分层布局而不会在 X 轴上重叠？
我尝试添加选项：
var options = {
layout: {
hierarchical: {
direction: "UD",
sortMethod: "directed"
},
physics: {
solver: "barnesHut"
,barnesHut: {
avoidOverlap: 1
}
}
}
};
您可以增加layout.hierarchical.nodeSpacing初始布局。
// create an array with nodes
var nodes = new vis.DataSet([
{id: 1, label: 'Node 1 with lage text'},
{id: 2, label: 'Node 2 with lage text'},
{id: 3, label: 'Node 3 with lage text'},
{id: 4, label: 'Node 4 with lage text'},
{id: 5, label: 'Node 5 with lage text'}
]);
// create an array with edges
var edges = new vis.DataSet([
{from: 1, to: 3},
{from: 1, to: 2},
{from: 2, to: 4},
{from: 2, to: 5}
]);
// create a network
var container = document.getElementById('mynetwork');
var data = {
nodes: nodes,
edges: edges
};
var options = {
layout: {
hierarchical: {
direction: "UD",
sortMethod: "directed",
nodeSpacing: 200 // <-- !!!!!!!
}
},
physics: false
};
var network = new vis.Network(container, data, options);#mynetwork {
width: 100%;
height: 100%;
border: 1px solid lightgray;
