我正在使用 Cytoscape.js 构建一个 Web 应用程序，它可以可视化蛋白质相互作用数据。
蛋白质(节点)需要具有对应于表示其染色体位置的字符串的 ID，因为这是通用的。但是，我希望将它们可视化或显示在它们的常用名称旁边，而不是它们的 ID。
知道怎么做吗？ Cytoscape 文档似乎没有答案。
最佳答案
您可以在数据字段中指定节点名称。如果您想将该名称显示为节点标签，只需使用字段 label: "data(name)" :
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),
boxSelectionEnabled: false,
autounselectify: true,
style: [{
selector: "node",
css: {
label: "data(name)", //access the nodes data with "data(...)"
// label: "data(id)",
"text-valign": "center",
"text-halign": "center",
height: "60px",
width: "100px",
shape: "rectangle",
"background-color": "data(faveColor)"
}
},
{
selector: "edge",
css: {
"curve-style": "bezier",
"control-point-step-size": 40,
"target-arrow-shape": "triangle"
}
}
],
elements: {
nodes: [{
data: {
id: "Top",
faveColor: "#2763c4",
name: "Steve"
}
},
{
data: {
id: "yes",
faveColor: "#37a32d",
name: "Larry"
}
},
{
data: {
id: "no",
faveColor: "#2763c4",
name: "Kiwi"
}
},
{
data: {
id: "Third",
faveColor: "#2763c4",
name: "Alex"
}
},
{
data: {
id: "Fourth",
faveColor: "#56a9f7",
name: "Vader"
}
}
],
edges: [{
data: {
source: "Top",
target: "yes"
}
},
{
data: {
source: "Top",
target: "no"
}
},
{
data: {
source: "no",
target: "Third"
}
},
{
data: {
source: "Third",
target: "Fourth"
}
},
{
data: {
source: "Fourth",
target: "Third"
}
}
]
},
layout: {
name: "dagre"
}
}));body {
font: 14px helvetica neue, helvetica, arial, sans-serif;
}
#cy {
height: 100%;
width: 100%;
left: 0;
top: 0;
float: left;
position: absolute;
