How to use dagre layout in cytoscape.js to draw a simple tree. I am putting layout{ name: ‘dagre’} and added dagre.js but not works.With arbor.js it works but I would like to use dagre to see the tree results. I'm newbie with javascript. Many thanks and sorry for my Englihs! My code:

(1) You shouldn't reference your JS file from your local drive. Use a http:// or https:// URL.
(2) You haven't specified 'dagre' to run at init. Set layout: { ... }.

This is the code sample that I am using in reactjs.
const node = graph.$(`#${selectedNode.id()}`);
graph.remove(node);
selectedNode.id is the id of the parent node but it deletes all the children nodes inside this parent node.
How can I delete the parent node only and not its descendants?
This question is similar to this on here Remove/hide compound node without removing/hiding descendants but I will appreciate it if some code samples are provided because in the doc here http://js.cytoscape.org/#collection/graph-manipulation/eles.move we have a shallow code example of edges but I am interested in nodes.
Thanks
You can delete a parent node by first moving its children to the parent's parent (if it exist, otherwise you should assig a null value) and then removing the parent node. Select a parent node and click on the delete button in the below example.
var cy = window.cy = cytoscape({
container: document.getElementById('cy'),
layout: {name: 'grid', rows: 2},
style: [{
selector: 'node',
css: {
'label': 'data(id)'
}
}
],
elements: {
nodes: [{
data: {
id: 'n0',
parent: 'n1'
}
},
{
data: {
id: 'n1',
parent: 'n2'
}
},
{
data: {
id: 'n2'
}
},
{
data: {
id: 'n3'
}
}
],
edges: [
{
data: {
id: 'n2n3',
source: 'n2',
target: 'n3',
weight: 7
}
}
]
}
});
document.getElementById("deleteButton").addEventListener("click", function() {
let selected = cy.nodes(':selected')[0];
selected.children().move({parent : (selected.parent().id() ? selected.parent().id() : null)});
selected.remove();
});
body {
font: 14px helvetica neue, helvetica, arial, sans-serif;

#button {
z-index = 1000;

#cy {

I have a problem with this plugin. I want to double click on nodes and the id of nodes should be displayed in console. I added the link of this extension from https://github.com/fixpoint/cytoscape-dblclick and followed by this post Cytoscape js - Call a function whenever a node is clicked, but still is not working.
Is anybody have any idea why it is not working, it would be nice if you share it.
You can see my code:
$(function() {
var elements = {
nodes: [

edges: [

};
function randomNumber(a) {
return Math.floor(Math.random() * (a));
}
var cy = window.cy = cytoscape({
container: document.getElementById('cy'),
ready: function() {},

}

});
cy.dblclick();
cy.on('dblclick', function(evt) {
console.log('dblclick');
cy.animate({
fit: {
eles: evt.target,
padding: 10,
},
});
});
cy.on('dblclick:timeout', function(evt) {
console.log('dblclick:timeout');
});
var ab = 12;
for (var i = 0; i < ab; i++) {
//elements.nodes.push({ "data": { "id": i } });
cy.add([{

Just follow the post you already linked and log the node information instead of fitting the graph to the clicked node. Also, your demo had some static scripts in the header, I removed them for that reason. That way, the qtip works again too:
$(function() {
var elements = {
nodes: [
],
edges: [
]
};
function randomNumber(a) {
return Math.floor(Math.random() * (a));
}
var cy = window.cy = cytoscape({
container: document.getElementById('cy'),
ready: function() {},
style: [{
selector: "node", //edge
style: {
content: "data(id)",
shape: "roundrectangle", //square, circle
"text-valign": "center",
"text-halign": "center",
height: "60px", //new
width: "100px", //new
//padding: "10px", //new
"text-wrap": 'wrap', //new
color: "#fff",
"background-color": "#11479e",
// "background-color": "data(faveColor)"
}
},
{
//arrows
selector: "edge",
style: {
"curve-style": "taxi",
//'background-color': '#008000',
width: 4,
"target-arrow-shape": "triangle",
"line-color": "#9dbaea",
"target-arrow-color": "#9dbaea"
}
}
],
});
cy.dblclick();
cy.on('dblclick', function(evt) {
console.log(evt.target.id());
});
var ab = 12;
for (var i = 0; i < ab; i++) {
//elements.nodes.push({ "data": { "id": i } });
cy.add([{
group: "nodes",
data: {
id: i
}
}
])
}
var cb = 20;
for (var i = 0; i < cb; i++) {
cy.add([{
group: "edges",
data: {
source: randomNumber(ab),
target: randomNumber(ab)
}
}])
}
cy.layout({

I am working on a cytoscape.js graph in browser. I want to show some information of nodes (e.g. node label) as the mouse hovers over the nodes in a cytoscape graph. The following code is working for console.log() but I want to show the information in the browser:
cy.on('mouseover', 'node', function(evt){
var node = evt.target;
console.log( 'mouse on node' + node.data('label') );
});
Please help !
Cytoscape.js has popper.js with tippy. I can give you a working exapmle for popper.js:
popper with tippy:
document.addEventListener("DOMContentLoaded", function() {
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),
style: [{
selector: "node",
style: {
content: "data(id)"
}
},
{

style: {
"curve-style": "bezier",
"target-arrow-shape": "triangle"
}
}
],
elements: {
nodes: [{
data: {
id: "a"
}
}, {
data: {
id: "b"
}
}],
edges: [{
data: {
id: "ab",
source: "a",
target: "b"
}
}]
},
layout: {
name: "grid"
}
}));
function makePopper(ele) {
let ref = ele.popperRef(); // used only for positioning
ele.tippy = tippy(ref, { // tippy options:
content: () => {
let content = document.createElement('div');
content.innerHTML = ele.id();
return content;
},
trigger: 'manual' // probably want manual mode
});
}
cy.ready(function() {
cy.elements().forEach(function(ele) {
makePopper(ele);
});
});
cy.elements().unbind('mouseover');
cy.elements().bind('mouseover', (event) => event.target.tippy.show());
cy.elements().unbind('mouseout');
cy.elements().bind('mouseout', (event) => event.target.tippy.hide());
});

Hi guys the Stephan's answer won't work using module based code like in React.js so I'm giving you an alternative without tippy
popper.css // popper style
.popper-div { // fill free to modify as you prefer
position: relative;
background-color: #333;
color: #fff;
border-radius: 4px;
font-size: 14px;
line-height: 1.4;
outline: 0;
padding: 5px 9px;
}
App.js
import cytoscape from "cytoscape";
import popper from "cytoscape-popper"; // you have to install it
import "./popper.css";
cytoscape.use(popper);
const cy = cytoscape({....});
cy.elements().unbind("mouseover");
cy.elements().bind("mouseover", (event) => {
event.target.popperRefObj = event.target.popper({
content: () => {
let content = document.createElement("div");
content.classList.add("popper-div");
content.innerHTML = event.target.id();
document.body.appendChild(content);
return content;
},
});
});
cy.elements().unbind("mouseout");
cy.elements().bind("mouseout", (event) => {
if (event.target.popper) {
event.target.popperRefObj.state.elements.popper.remove();
event.target.popperRefObj.destroy();
}
});
There are several posts about edge or edge label overlaps in Cytoscape.js but the answers given there, like smaller labels and more spaced out nodes, don't help for a multigraph, i.e. a graph where two nodes can have multiple edges between them.
Is there a way to spread out edge labels even if they all belong to edges between the same two nodes? The edge pairs occur both in the same direction and in the reverse one.
As my graph is verly large, I would prefer a solution with haystack edges as the performance is already low.
Well you can rotate the text with "text-rotation": "autorotate" in the labels css. You can also define the "text-margin-x/y" for each node itself, but how do you plan on defining the position for each and every label? Lets assume, you did that perfectly: you would still need to do a reposition event after moving just one node, because the offsets will be off by then:
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),

The problem breaks down to this: the task seems simple, but keeping track of the positions of all nodes and the edges aaaaand your rendered labels is a sisyphean task.
I'm looking for a way of getting QTip to concurrently display tooltips for each node in a Cytoscape.js graph, such that they are always displayed and anchored to the nodes in the graph without the user having to click or mouseover the node.
I got close with the code below:
$(document).ready(function(){
cy.nodes().qtip({
content: function(){ return 'Station: ' + this.id() +
'</br> Next Train: ' + this.data('nextTrain') +
'</br> Connections: ' + this.degree();
},
hide: false,
show: {
when: false,
ready: true
}
})
})
The above code displays tooltips on $(document).ready, but they are all located at one node in the Cytoscape graph and they disappear when I zoom in or pan at all.
The goal is to have tooltips anchored to each node in my graph such that when I zoom in and pan around they remain fixed to that node. I'm not sure if there is an easier way to do this just using Cytoscape (i.e., multi-feature labelling).
I'm using Qtip2, jQuery-2.0.3 and the most recent release of cytoscape.js
Any help is much appreciated.
EDIT: If you want to create these elements automatically, use a function and a loop to iterate over cy.nodes():
var makeTippy = function (nodeTemp, node) {
return tippy(node.popperRef(), {
html: (function () {
let div = document.createElement('div');
// do things in div
return div;
})(),
trigger: 'manual',
arrow: true,
placement: 'right',
hideOnClick: false,
multiple: true,
sticky: true
}).tooltips[0];
};
var nodes = cy.nodes();
for (var i = 0; i < nodes.length; i++) {
var tippy = makeTippy(nodes[i]);
tippy.show();
}
If you want a sticky qTip, I would instead recommend the cytoscape extension for popper.js and specificly the tippy version (sticky divs):
document.addEventListener('DOMContentLoaded', function() {
var cy = window.cy = cytoscape({
container: document.getElementById('cy'),
style: [{
selector: 'node',
style: {
'content': 'data(id)'
}
},
{
selector: 'edge',
style: {
'curve-style': 'bezier',
'target-arrow-shape': 'triangle'
}
}
],
elements: {
nodes: [{
data: {
id: 'a'
}
},
{
data: {
id: 'b'
}
}
],
edges: [{
data: {
source: 'a',
target: 'b'
}
}]
},
layout: {
name: 'grid'
}
});
var a = cy.getElementById('a');
var b = cy.getElementById('b');
var makeTippy = function(node, text) {
return tippy(node.popperRef(), {
html: (function() {
var div = document.createElement('div');
div.innerHTML = text;
return div;
})(),
trigger: 'manual',
arrow: true,
placement: 'bottom',
hideOnClick: false,
multiple: true,
sticky: true
}).tooltips[0];
};
var tippyA = makeTippy(a, 'foo');
tippyA.show();
var tippyB = makeTippy(b, 'bar');
tippyB.show();
});
body {
font-family: helvetica neue, helvetica, liberation sans, arial, sans-serif;
font-size: 14px
}
#cy {
position: absolute;
left: 0;
top: 0;
bottom: 0;
right: 0;
z-index: 1;
}
h1 {
opacity: 0.5;
font-size: 1em;
font-weight: bold;
}
/* makes sticky faster; disable if you want animated tippies */
.tippy-popper {
transition: none !important;
}

I think popper is just easier to handle when having the divs 'stick around'
