CytoscapeJS - show node neighborhood?

由 [亡魂溺海] 提交于 2019-12-10 20:59:11
问题 I have a dataset in JSON format containing information about nodes and edges which I am using to generate a network graph in cytoscapeJS. The JSON data contains id, value, shape, colour and visibleDisplay ('element' or 'none') attributes for nodes and id, source, target and label for edges . My stylesheet uses this 'visibleDisplay' property to show/ hide nodes, as needed, when the cy container is first initialised. I want to allow users to unhide nodes with an option to "Show neighbourhood" .

Cytoscape.js - selector for edges attached to selected node

由 社会主义新天地 提交于 2019-12-10 13:46:29
问题 I want to set the color of all edges that are attached to a selected node, so that each time a user selects a node any edges that the node is either a source or target of will be a different color. What would the selector look like for this, or is it not possible? 回答1: You can't just use a selector, because you need a small graph traversal in addition to the initial filter, e.g.: cy.$('node:selected').neighborhood('edge') ; i.e. for selected nodes get all connected edges Or cy.$('node

问题 I am having trouble having two instances of cytoscape setup on same webpage. I have two window vars "cy" and "cy2" that are being used for different graphs. They are functionally different graphs and need to be available on different parts of the page. I wanted to know how to get that setup correctly? When I look at page elements, the one not showing has the width and height of the underlying canvases set to 0 by cytoscape.js. Can you please help me to understand what is being initialized
