How to change what appears on top of a vertex AGE Viewer-CodePudding

I have created two vertices, one with label "Book" and another with label "User". The "Book" vertex has a property called "title" and the "User" vertex has the properties "first_name" and "last_name".

SELECT * FROM cypher ('goodreads_db', $$
MATCH (v)
RETURN v
$$) as (v agtype);

        v                                                                                                            
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
 {"id": 844424930131969, "label": "User", "properties": {"read": 9, "country": "Brazil", "reading": 2, "last_name": "Matsumoto", "first_name": "Matheus"}}::vertex
 {"id": 1125899906842625, "label": "Book", "properties": {"pages": 336, "title": "To Kill a Mockingbird", "author": "Harper Lee", "rating": 4.27, "ratings": 5574002, "reviews": 107847, "language": "English"}}::vertex
(2 rows)

When I try to visualize these nodes on AGE Viewer, it does not show the book title nor the user's first name on top of their vertices. Instead, it shows the book's id and nothing on the user's vertex (image below). Is there any way that I can output the book's title and the user's first name instead of what is currently displaying? If so, how?

CodePudding user response：

Yes! Apache-age provides you the facility to visualize the properties on the top of their vertices.

First properties inserted in the node while creating it will be shown on the top of the node. So in your case you should keep the book title and user's first name as the first property while creating the node.

Since it depends on the creation of nodes, if you had provided the query for creating nodes then I would be more clear to work on problem. But I have took example to show the working.
Let's walk through the example to clearly understand it.

First let's create PERSON nodes

SELECT * FROM cypher('graph_one', $$ CREATE (n:Person {name : "Kamlesh", bornIn : "Pakistan"}) $$) AS (a agtype);
SELECT * FROM cypher('graph_one', $$ CREATE (n:Person {name : "John", bornIn : "US"}) $$) AS (a agtype);
SELECT * FROM cypher('graph_one', $$ CREATE (n:Person {name : "Matheus", bornIn : "US"}) $$) AS (a agtype);
SELECT * FROM cypher('graph_one', $$ CREATE (n:Person {name : "akabr", bornIn : "Pakistan"}) $$) AS (a agtype);

Now creates some nodes for COUNTRY.

SELECT * FROM cypher('graph_one', $$ CREATE (n:Country{name : "Pakistan"}) $$) AS (a agtype);
SELECT * FROM cypher('graph_one', $$ CREATE (n:Country{name : "US"}) $$) AS (a agtype);

Create the relationship between nodes

SELECT * FROM cypher('graph_one', $$ MATCH (a:Person), (b:Country) WHERE a.bornIn = b.name CREATE (a)-[r:BORNIN]->(b) RETURN r $$) as (r agtype);

Visualizeing the graph created.

SELECT * from cypher('graph_one', $$ MATCH (a:Person)-[r]-(b:Country) WHERE a.bornIn = b.name RETURN a, r, b $$) as (a agtype, r agtype, b agtype);

Here is the result:

Thumbs up if you found it useful!

I don't think you can change what shows on the top as of now in Age Viewer. But you can do that on the console:

You can find a way to change the id value to an alias, but as of now we cannot change what's on top.
