How to highlight the path between two nodes in CYTOSCAPE JS

How to highlight the path between two nodes in CYTOSCAPE JS - javascript

i can create a graph using cytoscape js library . i am following the this tutorial and i implement like this.
CODE:
$(function(){ // on dom ready
$('#cy').cytoscape({
style: cytoscape.stylesheet()
.selector('node')
.css({
'content': 'data(id)'
})
.selector('edge')
.css({
'target-arrow-shape': 'triangle',
'width': 4,
'line-color': '#ddd',
'target-arrow-color': '#ddd'
})
.selector('.highlighted')
.css({
'background-color': '#61bffc',
'line-color': '#61bffc',
'target-arrow-color': '#61bffc',
'transition-property': 'background-color, line-color, target-arrow-color',
'transition-duration': '0.5s'
}),
elements: {
nodes: [
{ data: { id: 'a' } },
{ data: { id: 'b' } },
{ data: { id: 'c' } },
{ data: { id: 'd' } },
{ data: { id: 'e' } },
{ data: { id: 'f' } },
{ data: { id: 'g' } }
],
edges: [
{ data: { id: 'ab', weight: 1, source: 'a', target: 'b' } },
{ data: { id: 'ac', weight: 2, source: 'a', target: 'c' } },
{ data: { id: 'bd', weight: 3, source: 'b', target: 'd' } },
{ data: { id: 'be', weight: 4, source: 'b', target: 'e' } },
{ data: { id: 'cf', weight: 5, source: 'c', target: 'f' } },
{ data: { id: 'cg', weight: 6, source: 'c', target: 'g' } }
]
},
layout: {
name: 'breadthfirst',
directed: true,
roots: '#a',
padding: 5
},
ready: function(){
window.cy = this;
var bfs = cy.elements().bfs('#a', function(){}, true);
var i = 0;
var highlightNextEle = function(){
bfs.path[i].addClass('highlighted');
if( i < bfs.path.length ){
i++;
setTimeout(highlightNextEle, 1000);
}
};
// kick off first highlight
highlightNextEle();
}
});
}); // on dom ready
on my implementation i need to highlight the path between the nodes d and g.
How to find the path between the nodes and highlight them?

Using dijkstra algorithm method we can find the path between the nodes.
var dijkstra = cy.elements().dijkstra('#e',function(){
return this.data('weight');
},false);
var bfs = dijkstra.pathTo( cy.$('#i') );
Complete CODE :
$(function(){ // on dom ready
$('#cy').cytoscape({
style: cytoscape.stylesheet()
.selector('node')
.css({
'content': 'data(id)'
})
.selector('edge')
.css({
'target-arrow-shape': 'triangle',
'width': 4,
'line-color': '#ddd',
'target-arrow-color': '#ddd'
})
.selector('.highlighted')
.css({
'background-color': '#61bffc',
'line-color': '#61bffc',
'target-arrow-color': '#61bffc',
'transition-property': 'background-color, line-color, target-arrow-color',
'transition-duration': '0.5s'
}),
elements: {
nodes: [
{ data: { id: 'a' } },
{ data: { id: 'b' } },
{ data: { id: 'c' } },
{ data: { id: 'd' } },
{ data: { id: 'e' } },
{ data: { id: 'f' } },
{ data: { id: 'g' } },
{ data: { id: 'h' } },
{ data: { id: 'i' } }
],
edges: [
{ data: { id: 'ab', weight: 1, source: 'a', target: 'b' } },
{ data: { id: 'ac', weight: 2, source: 'a', target: 'c' } },
{ data: { id: 'bd', weight: 3, source: 'b', target: 'd' } },
{ data: { id: 'be', weight: 4, source: 'b', target: 'e' } },
{ data: { id: 'cf', weight: 5, source: 'c', target: 'f' } },
{ data: { id: 'cg', weight: 6, source: 'c', target: 'g' } },
{ data: { id: 'ah', weight: 7, source: 'a', target: 'h' } },
{ data: { id: 'hi', weight: 8, source: 'h', target: 'i' } }
]
},
layout: {
name: 'breadthfirst',
directed: true,
roots: '#a',
padding: 5
},
ready: function(){
window.cy = this;
var dijkstra = cy.elements().dijkstra('#e',function(){
return this.data('weight');
},false);
var bfs = dijkstra.pathTo( cy.$('#i') );
var x=0;
var highlightNextEle = function(){
var el=bfs[x];
el.addClass('highlighted');
if(x<bfs.length){
x++;
setTimeout(highlightNextEle, 500);
}
};
highlightNextEle();
}
});
}); // on dom ready

I you want to highlight all the possible paths
event.target- is the starting node
event.target.successors().animate({
style: { lineColor: 'red' }
});

Assuming you have picked two nodes and stored them in source_node and target_node, and you want to label everything in between with class 'path_element':
p = cy.elements().aStar({root: source_node, goal: target_node, directed: true}).path;
if (p) {
p.filter(function(i,x) { return x != source_node && x != target_node; })
.addClass('path_element');
p.edgesWith(p)
.addClass('path_element');
}

EdgeClick on reactflow's subflow doesn't trigger

I have my nodes like this
const nodes = [
{
id: 'A',
type: 'group',
data: { label: null },
position: { x: 0, y: 0 },
style: {
width: 170,
height: 140,
},
},
{
id: 'B',
type: 'input',
data: { label: 'child node 1' },
position: { x: 10, y: 10 },
parentNode: 'A',
extent: 'parent',
},
{
id: 'C',
data: { label: 'child node 2' },
position: { x: 10, y: 90 },
parentNode: 'A',
extent: 'parent',
},
];
export default nodes;
..and have connection between them
export default [{ id: 'b-c', source: 'B', target: 'C' }];
A is a parent node and B,C are its child nodes. But when clicking on edges with in a subflow group, the onEdgeClick does not trigger. But the same prop works when the edge is not inside a group ( subflow ) !
Highly appreciate any help on which direction to look for a solution!

Cytoscape.js - Find all common nodes and retain them

I have a graph: B -> A, C -> A, C -> D where node B and node C are of the same type.
I would like to find and retain only the common nodes shared between the nodes which is node A.
How do i filter and remove out the nodes C -> D while retaining the rest of the graph?

You can filter the graph with some handy methods:
// get node a
let node_a = cy.$('#a');
// get edges to -> b and c
let connected_edges = node_a.connectedEdges()
// get source and target nodes -> a, b and c
let connedted_nodes = connected_edges.connectedNodes()
// get target nodes -> b and c
let target_nodes = connected_edges.targets()
// Then you can remove the unwanted nodes (you may have to manage the edges too)
let removed_nodes = cy.remove(cy.nodes().not(connected_nodes)
Here is a working example:
var cy = window.cy = cytoscape({
container: document.getElementById('cy'),
boxSelectionEnabled: false,
autounselectify: true,

Cytoscape.js all nodes are on top of each other when created in a loop

I'm displaying a flowchart with values from a JSON file.
When I create my element in a static way, like this :
elements: {
nodes: [
{ data: { id: 'INIT' } },
{ data: { id: 'BUSINESS_RULES_1' } },
{ data: { id: 'EXPORT_STC' } },
{ data: { id: 'EXPORT_SPEC' } },
{ data: { id: 'COPY' } },
{ data: { id: 'MERGE' } },
{ data: { id: 'BUSINESS_RULES_2' } },
{ data: { id: 'TRANSFORM_ARP' } },
{ data: { id: 'TRANSFORM_APS' } },
{ data: { id: 'PUBLISH_APS' } },
{ data: { id: 'PUBLISH_ARP' } },
{ data: { id: 'ARCHIVE' } }
],
edges: [
{ data: { source: 'INIT', target: 'BUSINESS_RULES_1' } },
{ data: { source: 'BUSINESS_RULES_1', target: 'EXPORT_SPEC' } },
{ data: { source: 'BUSINESS_RULES_1', target: 'EXPORT_STC' } },
{ data: { source: 'EXPORT_STC', target: 'COPY' } },
{ data: { source: 'EXPORT_SPEC', target: 'COPY' } },
{ data: { source: 'COPY', target: 'MERGE' } },
{ data: { source: 'MERGE', target: 'BUSINESS_RULES_2' } },
{ data: { source: 'BUSINESS_RULES_2', target: 'TRANSFORM_APS' } },
{ data: { source: 'BUSINESS_RULES_2', target: 'TRANSFORM_ARP' } },
{ data: { source: 'TRANSFORM_ARP', target: 'PUBLISH_ARP' } },
{ data: { source: 'TRANSFORM_APS', target: 'PUBLISH_APS' } },
{ data: { source: 'PUBLISH_APS', target: 'ARCHIVE' } },
{ data: { source: 'PUBLISH_ARP', target: 'ARCHIVE' } }
]
}
It is well displayed as you can see :
But when I create the element in a dynamic way, like this :
// Fill array with nodes and edges
var arrayNodesAndEdges = [];
for (var i = 0; i < myJSONdata.length; i++) {
if(i < myJSONdata.length - 1 && (myJSONdata[i].OPERATION_NAME != myJSONdata[i+1].OPERATION_NAME)) {
console.log(i + " " +myJSONdata[i].OPERATION_NAME);
arrayNodesAndEdges.push({
group: "nodes",
data: {
id: myJSONdata[i].OPERATION_NAME
}
});
} else if(i == myJSONdata.length - 1) {
console.log(i + " " +myJSONdata[i].OPERATION_NAME);
arrayNodesAndEdges.push({
group: "nodes",
data: {
id: myJSONdata[i].OPERATION_NAME
}
});
}
}
for (var i = 0; i < myJSONdata.length; i++) {
var source = myJSONdata[i].OPERATION_NAME;
if(myJSONdata[i].NEXT_OPERATION_NAME !== "" && myJSONdata[i].NEXT_OPERATION_NAME !== null) {
console.log("Source: " + myJSONdata[i].OPERATION_NAME + ", " + "Target: " +myJSONdata[i].NEXT_OPERATION_NAME);
arrayNodesAndEdges.push({
group: "edges",
data: {
id: "e"+i,
source: source,
target: myJSONdata[i].NEXT_OPERATION_NAME
}
});
}
}
cy.add(arrayNodesAndEdges);
It is bad displayed, all nodes are on top of each other, as you can see:
(I moved some to explain how they are positionned, but they are all on top of each other)
Here's the console log, you can see this is the same structure in static or dynamic way :
NODES
0 INIT
2 BUSINESS_RULES_1
3 EXPORT_STC
4 EXPORT_SPEC
5 COPY
6 MERGE
8 BUSINESS_RULES_2
9 TRANSFORM_ARP
10 TRANSFORM_APS
11 PUBLISH_APS
12 PUBLISH_ARP
13 ARCHIVE
EDGES
Source: INIT, Target: BUSINESS_RULES_1
Source: BUSINESS_RULES_1, Target: EXPORT_SPEC
Source: BUSINESS_RULES_1, Target: EXPORT_STC
Source: EXPORT_STC, Target: COPY
Source: EXPORT_SPEC, Target: COPY
Source: COPY, Target: MERGE
Source: MERGE, Target: BUSINESS_RULES_2
Source: BUSINESS_RULES_2, Target: TRANSFORM_APS
Source: BUSINESS_RULES_2, Target: TRANSFORM_ARP
Source: TRANSFORM_ARP, Target: PUBLISH_ARP
Source: TRANSFORM_APS, Target: PUBLISH_APS
Source: PUBLISH_APS, Target: ARCHIVE
Source: PUBLISH_ARP, Target: ARCHIVE
I can't understand what I'm doing wrong ?

How to select nodes by class in cytoscape.js?

CYTOSCAPE.JS
I can't manage to apply styles to a class defined in node-data (clLevel0). I wrote a function to work around the problem. So, the function also explains what i want to do, in a much simpler way that is ;-)
function setNodesClassStyles(cy, clas, styleobject)
{
var all = cy.nodes();
for (i = 0; i < all.length; i++) {
the_node = all[i];
all_classes = the_node.data().classes;
//alert(all_classes);
if (all_classes != undefined) {
all_classes = all_classes.split(' ');
for (i = 0; i < all_classes.length; i++) {
alert(all_classes[i]);
if (clas == all_classes[i]) {
the_node.style(styleobject)
}
}
}
}
};
setNodesClassStyles(cy, "clLevel0", {'background-color':'#00E'});
I tried this (not working):
{
selector: ".clLevel0",
style: {
'background-color': '#EAA',
}
},
What's the right way to apply styles on a node with a class 'clas'?
More code:
var cy = cytoscape({

Highcharts - drill down to multiple series

I have a parent chart that I need to drill down to a child chart with multiple series. Here is a toy example of what I would like to do. (I know this does not work)
Notice I'm trying to pass in an array of ids to display in the child chart.
Does anybody know a way to do this? If someone from Highcharts reads this, can this be added as a feature?
$(function () {
// Create the chart
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Basic drilldown'
},
xAxis: {
type: 'category'
},
plotOptions: {
column : {
stacking : 'normal'
}
},
series: [{
name: 'Yearly Orders',
data: [{
name: 'Location 1',
y: 100,
drilldown: ['l1-wa', 'l1-wb']
}, {
name: 'Location 2',
y: 150,
drilldown: ['l2-wa', 'l2-wb']
}]
}],
drilldown: {
series: [{
name: 'Widget A',
type: 'line',
id: 'l1-wa',
data: [
{name: 'Qtr 1', y: 5},
{name: 'Qtr 2', y: 25},
{name: 'Qtr 3', y: 25},
{name: 'Qtr 4', y: 20}
]
},{
name: 'Widget B',
type: 'line',
id: 'l1-wb',
data: [
{name: 'Qtr 1', y: 10},
{name: 'Qtr 2', y: 5},
{name: 'Qtr 3', y: 5},
{name: 'Qtr 4', y: 5}
]
}, {
name: 'Widget A',
type: 'line',
id: 'l2-wa',
data: [
{name: 'Qtr 1', y: 25},
{name: 'Qtr 2', y: 5},
{name: 'Qtr 3', y: 5},
{name: 'Qtr 4', y: 15}
]
},{
name: 'Widget B',
type: 'line',
id: 'l2-wb',
data: [
{name: 'Qtr 1', y: 30},
{name: 'Qtr 2', y: 30},
{name: 'Qtr 3', y: 15},
{name: 'Qtr 4', y: 25}
]
}
]
}
})
});
Here is a JSFiddle of this drilling down to just one series http://jsfiddle.net/F7z3D/2/

Found a neat solution here
Uses a drillup option,
Highcharts.setOptions({
lang: {
drillUpText: '<< Go Back {series.name}'
}
});

A workaround for a drillup button in combination with the setChart() solution, can be to add a hyperlink (e.g. in a subtitle). Then give the original data to setChart()
$(document).on('click', '#drillup', function () {
var data = {categories: categories, series: series};
setChart('new title', categories, data, chart.type);
});
