How to edit node in graph?

[SN1979]

Hi

I can get the all the nodes in graph.
But they can't be updated.
I have to drop them first, and add them again after update.
Are there any other ways to do that?

Thanks

Sigma has it's own bind method that might be more convenient, ie clicknode....

sigma.js/src/sigma.core.js

Lines 345 to 363 in 188a0bf

	// Bind events:
	if (renderer.bind)
	renderer.bind(
	[
	'click',
	'clickStage',
	'clickNode',
	'clickNodes',
	'overNode',
	'overNodes',
	'outNode',
	'outNodes',
	'downNode',
	'downNodes',
	'upNode',
	'upNodes'
	],
	this._handler
	);

Hi

I add a click function to dom, and it works, as following code shows. But I can only get all the nodes in graph.
How to get the node that I just click? Thanks.

dom = document.querySelector('#graph-container canvas:last-child');
dom.addEventListener('click', function (e) {
var clickedNode = s.graph.nodes();
window.console.log("clicked!!!!");
s.refresh();
}, false);

Hello @SN1979

When iterating on graph's nodes, you are given a reference to said nodes so you can modify them.

For instance:

// Modifying nodes
sigmaInstance.graph.nodes().forEach(node) {
  // Node is a reference to your node in the graph
  node.color = 'your-new-color';
});

// Don't forget to refresh to display your changes
sigmaInstance.refresh();
