Large Graph Example - Find Neighbors Functionality Not Working

[mzhukovs]

Describe the bug

Thank you for this great library and excellent example: https://g6.antv.vision/en/examples/case/graphDemos#largeGraph

In that Large Graph Example though, if you right click on a real (non-aggregated node) and select "Find N-degree Neighbors" from the context menu - it will add a bunch of new nodes to the graph with "undefined" labels. Does not seem to be working correctly.

P.S. is there another example, or a recommended way to update this current example, to handle the case of multiple levels of clustered groups? For example, a top-level cluster could contain a few sub-clusters, and each of those may contain either the "real nodes" or even more child clusters of their own). Please let me know, would be much appreciated.

Steps to Reproduce the Bug or Issue

if you view that Example and right click on a real (non-aggregated node) and select "Find N-degree Neighbors" - it will add a bunch of new nodes to the graph with "undefined" labels.

Expected behavior

It would highlight in some way the first/second/third degree neighbors to the current node that the context menu option was used on.

The label with undefined-xxx is generate by G6.Util.uniqueId() which is defined as

export const uniqueId = (type: string): string => {
  return `${type}-${Math.random()}${Date.now()}`;
};

So the undefined comes from the undefined param type. In the large graph example, the type is missed when calling uniqueId, I will update the code ASAP.

P.S. is there another example, or a recommended way to update this current example, to handle the case of multiple levels of clustered groups? For example, a top-level cluster could contain a few sub-clusters, and each of those may contain either the "real nodes" or even more child clusters of their own).

I think it just some different implementation for the function generateNeighbors in the large graph demo

I have the same problem. What shoud I do to show the label nodes of the N-degree neighbors?
