Cypher Query to show Node Labels in Graph

Neo4j Graph Platform Cypher
1

Hello

So i have a simple cypher query that returns the below graph image. However, the graph at some locations contains NO node labels and in other locations DOES contain node labels.

I recall that there is a cypher query statement that can be implemented to force all node labels to show in the graph? I was wondering if someone could assist me with this query.

Not aware of a Cypher query for this, but you can pick the right property to show for the labels that do not have a value displayed from the browser/Neo4j desktop browser

There are a few things that could be happening here, but to be more precise, we'll need the Cypher query you're running.

  1. The text on a node in the Browser defaults to the value of the name property of that node.
  2. In the browser, you can select which property will be used for the text, for specific Labels.

The nodes which have no text have no value to display. It's that simple.

Breakdown

CREATE (a:Example {name:'this', name2: 'that'})

Click the Label at the top

And then chose a property at the bottom:

If you delete that property...

Showing labels in your graph.

The only way to do that reliably, without mutating your data, is with virtual nodes.

That's a deep rabbit-hole, so I'm not going into it.

The other thing you can do is just create a new property, and set it to the string of your labels...

MATCH (a)
SET a :Ex2
SET a.nameLabel = REDUCE(res = "", x in labels(a) | x + ", " + res)
RETURN a
