As you can see below not all the node style that i declare are working. I want to make the text inside the node larger and in the documentation i found the code: 'labelFontSize': 100. Than, i want to make the edge weight (that you cannot see in the picture but are present) white, and the code "labelFontColor": "white" isn't working. I am using CytoscapeJs.
Can someone explain to me why this happen?
My code is the following:
var json_obj = response.Cy_json_archi_prima_di_chiusura_atk_supp
var cy = cytoscape({
container: document.getElementById('cy_atk_supp'),
elements: JSON.parse(json_obj),
style: [
{
selector: 'node',
style: {
'shape': 'circle',
'labelFontSize': 100,
'label': 'data(label)',
'text-valign': 'center',
'text-halign': 'center',
'color': 'black',
"height": 150,
"width": 150,
'border-width': '2px',
'border-color': 'black',
'background-color': '#399AF9'
//'font-size': 20
}
},
{
selector: 'edge',
style:{
'label': 'data(weight)',
'labelFontSize': 300,
"labelFontColor": "white",
'labelFontWeight': 'bold',
'lineColor': 'data(color)',
'width': 3,
'target-arrow-color': 'data(color)',
"curve-style": "bezier",
'target-arrow-shape': 'triangle',
}
}
],
layout: {
name : 'circle'
}
});
And this is the resulting Graph:
I was checking the wrong library.
For cytoscapeJS these is the correct style option: https://js.cytoscape.org/#style/labels

I made a simple page with the "PhotoSphereViewer" library and i want to add a couple of links, with the "Markers Plugin".
http://klappfon.info/xxxemanuel/2/
It works like a charm on firefox and safari, but unfortunately not at all on touch screens / phone browsers...
The links seems "clickable" (turning to active state, red) but does not open...
My theory is that it has something to do with the navigation of the sphere since link does open when "PhotoSphereViewer" is set to "TwoFingerMode"...
Any ideas how to work around that?
THANKS!!!
plugins: [PhotoSphereViewer.GyroscopePlugin,
[PhotoSphereViewer.MarkersPlugin,{markers:[{

You cannot add links to html markers because the click is intercepted. Instead you should attach custom datato the marker and use the select-marker event.
https://photo-sphere-viewer.js.org/plugins/plugin-markers.html#select-marker-marker-data
const viewer = new PhotoSphereViewer({
plugins: [PhotoSphereViewer.GyroscopePlugin,
[PhotoSphereViewer.MarkersPlugin,{markers:[{
id: '1',
className: 'link',
longitude: 0.7,
latitude: 0,
html: '1234',
anchor: 'bottom right',
scale: [0.5, 1.5],
style: {
maxWidth: '200px',
color: 'white',
fontSize: '30px',
fontFamily: 'Helvetica, sans-serif',
textAlign: 'center',
},
},
data: { href: 'http://google.com' },
]
}]
]
});
const markersPlugin = viewer.getPlugin(PhotoSphereViewer.MarkersPlugin);
markersPlugin.on('select-marker', (e, marker) => {
window.location.href = marker.data.href;
});
I have a text object in fabric.js that I am creating with:
fbText = new fabric.Textbox('#TEST', {
width: 700,
fill: '#303846',
top: 150,
left: 50,
fontSize: 150,
textAlign: 'left',
fixedWidth: 700,
// fontWeight: 'bold',
editable: false,
originY: 'center',
styles: {
// first word of text i.e Test
0: {
//first letter of first word i.e T
0: { fill: '#21bba6', fontSize: 130}
},
}
})
I would like to make the 1st letter higher than the rest of the word. Any thoughts on how that might be possible?
This is what I want to happen:
This is currently happening:
You can use deltaY negative value. There are more available style properties that can be used, have a look at [http://fabricjs.com/docs/fabric.Textbox.html#_styleProperties][1].
var fbText = new fabric.Textbox('#TEST', {
...,
styles: {
0: {
0: {
fill: '#21bba6',
fontSize: 130,
deltaY: -30
}
},
}
})
A major part of the project I'm building involves allowing users to create and edit DAGs fluidly. I'm using React, cytoscape.js, cytoscape edgehandles, and the dagre layout to accomplish this, and it's working pretty well, except for one annoying problem. When the graph only has a few nodes, the nodes are huge!
This is because I have fit set to true (the default) in the layout options. I need to keep this setting, because as the graphs grow I want them to zoom out to fit unless the user chooses to zoom in. I just don't want the first 1 - 4 nodes to be huge! Is there any way to define a max height/width for the nodes, or control the zoom level, or something, so that the nodes start off at a reasonable size and only start getting smaller when they have to?
Here's my layout:
cy.layout({
name: 'dagre',
ranker: 'longest-path',
padding: 15
}).run();
And here's my style settings:
const cyConfig = {
elements: [],
style: [
{
selector: 'node',
style: {
'label': 'data(name)',
'color': '#2C2029',
'text-valign':'center',
'text-halign': 'center',
'font-size': '25px',
'font-family': 'Nixie One, cursive',
'shape': 'roundrectangle',
'background-color': 'mapData(inDegree, 1, 8, rgba(163, 154, 164), rgba(240, 146, 60))',
'background-opacity': 'mapData(inDegree, 1, 8, .3, 1)',
'border-color': 'transparent',
'width': 'label',
'height': 'label',
'padding': '7px'
}
}, {
selector: 'edge',
style: {
'curve-style': 'bezier',
'target-arrow-shape': 'triangle',
'target-arrow-fill': 'hollow',
'target-arrow-color': '#2C2029',
'width': '1px',
'color': '#2C2029',
}
}
]
};
You can always define your nodes like this:
style: [
{
selector: 'node',
style: {
'shape': 'data(faveShape)',
'content': 'data(DisplayName)',
'height': 'data(faveHeight)',
'width': 'data(faveWidth)',
'background-color': 'data(faveColor)',
'line-color': '#a8eae5',
'font-family': 'Segoe UI',
'font-size': '15px',
}
}
]
If you do so, you can check how many nodes you want to add to your cytoscape window and then define their width and height properties according to the number of nodes you want to add:
jsonNew.push({
data: {
id: yourId,
parent: '',
faveShape: 'yourShape',
faveHeight: ((nodes.length > 7) ? nodes.length * 3 : nodes.length * 6),
faveWidth: ((nodes.length > 7) ? nodes.length * 5 : nodes.length * 10),
faveColor: '#ffffff'
},
position: {
x: '',
y: ''
},
parents: '',
group: 'nodes',
removed: false,
selected: false,
selectable: true,
locked: false,
grabbable: true,
classes: ''
});
I am trying to resize the shapes of the nodes to the size of the node text. I followed instructions from https://github.com/cytoscape/cytoscape.js/issues/649 . However:
The shapes always end up with height = width
The size of all shapes is the same.
The shape size seems to reach a max above which it can't grow.
(I am not sure if this has something to do with dagre layout.)
I am using the following libraries with the dagre layout:
cytoscape.min.js
dagre.min.js
cytoscape-dagre.js
container: document.getElementById('cy'),
boxSelectionEnabled: false, autounselectify: true,
layout: {name: 'dagre', rankDir: 'LR', align: 'LR'},
style: [{
selector: 'node',
style: {
'content': 'data(name)',
'label': 'data(name)',
'text-opacity': 1,
'text-valign': 'center',
'text-halign': 'center',
'text-wrap': 'wrap',
'font-size': 9,
'background-color': '#AAA',
'shape':'rectangle',
'width': 'data(width)' * 50,
'height': 'data(height)' * 50 }
},{
selector: 'edge',
style: {
'width': 4,
'content': 'data(name)',
'target-arrow-shape': 'triangle',
'line-color': 'data(color)',
'text-wrap': 'wrap',
'target-arrow-color': 'data(color)',
'font-size': 10,
}
}]
You've specified invalid style. "somestring" * 50 is NaN.
You want width: label, as indicated in the docs: http://js.cytoscape.org/#style/node-body
I created a custom element with the JointJS library . The object have two nested Rectangles with two associated Texts.
I want to change his atributtes inside de Model... I only get through JQUERY change his attributes and css, through its ids.
I want to change the attrs in the model and then, update the node to show his new look.
Sorry if I can not explain it well enough, I leave a jsFiddle ->
http://jsfiddle.net/y9ucn/
If you need additional information, please ask.
Thank you.
Here's the class who defines my custom object and on the jsfiddle you can play an example:
MyRect = joint.shapes.basic.Generic.extend({
markup: [
'<g class="rotatable">',
'<g class="scalable">',
'<rect class="firstRect"/><rect class="secondRect"/>',
'</g>',
'<text class="textFirstRect"/><text class="textSecondRect"/>',
'</g>'].join(''),
defaults: joint.util.deepSupplement({
type: 'basic.MyRect',
attrs: {
'.firstRect': {
'stroke': '#0A1317',
'stroke-width': 1,
'fill': '#DBF024',
'width': 100,
'height': 30,
},
'.secondRect': {
'stroke': '#0A1317',
'stroke-width': 1,
'fill': '#DBF024',
'width': 100,
'height': 30,
},
'.textFirstRect': {
'ref': '.firstRect',
'ref-x': .5,
'ref-y': .5,
'y-alignment': 'middle',
'x-alignment': 'middle',
'fill': '#333',
'font-size': 12,
'font-family': 'Calibri,Arial',
},
'.textSecondRect': {
'ref': '.secondRect',
'ref-y': .5,
'ref-x': .5,
'y-alignment': 'middle',
'x-alignment': 'middle',
'fill': '#333',
'font-size': 12,
'font-family': 'Calibri,Arial'
}
}
}, joint.shapes.basic.Generic.prototype.defaults),
initialize: function () {
_.bindAll(this, 'format');
this.format();
joint.shapes.basic.Generic.prototype.initialize.apply(this, arguments);
},
format: function () {
var attrs = this.get('attrs');
attrs['.secondRect'].transform = 'translate(0,30)';
}
});
You can use the attr() method:
cellView.model.attr('.textSecondRect/text', 'foo');
