I am building a charting tool in ember using cytoscape js and I can render chart data however I do not know how to set each node to display with a image that has other images/buttons that function within it. Basically I want it to look like this:
In the image there are two buttons (I will most likely add icons as well) and also there are labels that exist within the node which I don't know how to do either.
Here is the code I currently have.
Template:
<div class="container" >
<div id="cy"></div>
</div>
Component JS:
import Ember from 'ember';
export default Ember.Component.extend({
tagName: '',
map: Ember.computed('model.map_data', function()
{
if(this.get('model.map_data')){
return JSON.parse(this.get('model.map_data').data)
} else {
return {};
}
}),
cytoscape_data: Ember.computed('model.sub_apps.[]',function() {
var ret = {
nodes: [],
edges: []
};
var red = 50;//replace with threshold
var green = 25;//replace with threshold
var _this = this;
this.get("model").map_data.forEach(function(node) {
var y= 0;
var x = 0;
var color = 'green';
if(node.value >= red ){
color = 'red';
}else {
if(node.value > green){
color = 'orange';
}
}
var position = _this.get("map")["app" + node.id];
if(position){
x = parseInt(position.split(',')[0]);
y = parseInt(position.split(',')[1]);
}
ret["nodes"].push({
data: {
id: node.id,
label: node.name,
node_type: 'app',
tooltip: node.description,
color: color
},
position: {
x: x,
y: y
}
});
if(node.relations) {
node.relations.forEach(function(parent) {
ret["edges"].push({
data: {
source: node.id,
target: parent.app_to_id
}
});
});
}
});
return ret;
}),
didInsertElement: function() {
this._super();
var cy = cytoscape({
container: Ember.$('#cy')[0],
elements: this.get("cytoscape_data"),
zoom: 1,
pan: { x: 0, y: 0 },
fit: true,
randomize: false,
layout: {
name: 'preset'
},
style: [
{
selector: 'node',
style: {
'content': 'data(label)',
'text-opacity': 0.8,
'text-valign': 'center',
'text-halign': 'right',
'width': '200px',
'height': '200px',
'border-color': 'green',
'border-width': 3,
'border-opacity': 0.5,
'background-image': 'url(../assets/images/base_node_image.svg)'
// 'background-color': 'data(color)'
}
},
{
selector: 'edge',
style: {
'width': 6,
'border-color': 'green',
'target-arrow-shape': 'triangle',
'target-arrow-color': 'red',
'opacity': 1,
'curve-style': 'bezier'
}
},
{
selector: ':selected',
style: {
'background-color': 'orange',
'opacity': 1
}
},
{
selector: '.faded',
style: {
'opacity': 0.0,
'text-opacity': 0
}
},
],
});
Ember.run.scheduleOnce('afterRender', this, function(){
cy;
});
cy.on('click', 'node', function(evt){
var node = evt.target;
console.log( 'clicked ' + node.data('label') );
});
},
});
The chart this code renders looks like this:
I can display a background-image however it displays in a circle which I dont know how to get rid of. The color of the circle is determined by some logic above which was a test to see if it works and that is fine (going to use that for one of the icons on the node later). I can also display the label for the node but I don't know how to display that within the node itself.
Any help is appreciated, thanks!
