In the visualization, a lot of nodes don't show their node names. They look blank. Is that because for the node, I didn't create a 'name' attribute for it? In another words, in order to show the node with a text, must I create a 'name' property for that node?
By default neo4j looks for a name property to show as the node caption. But you can change it. In the admin console, write your cypher to get a graph back. Then at the top click on the label of the nodes you want to change caption for. Then at the bottom of the UI, next to the color pallet, there is a Caption section where you can choose a property to be shown as the caption for all the nodes of the selected label.

I am creating a set of nodes and would like to incorporate the concept of a Tag in Neo4j. When I create a node and use the specific word "Tag" for the label, it never shows up with "Tag" as the label. I can create the node exactly the same, but use a different word other than "Tag" and it will work. This only happens with the word "Tag", "tag", "TAG"
create (a:Product{name:'VirusScan Enterprise'})
create (b:Product{name:'Norton'})
create (c:Vendor{name:'Clam'})
create (d:Vendor{name:'McAfee'})
create (e:Vendor{name:'Symantec'})
create (n:Tag{name:'Antivirus'})
To point out, the "Tag" label is right there, in gray in the lower left of your screenshot.
But if you're talking about the caption instead, there's nothing that enforces what property should be used as a default caption in the graph result view, and sometimes no property is chosen as a caption by default.
To choose it yourself, click on the "Tag" label (the labels are shown in the upper-left of the graph results view), and that should reveal some options at the bottom of the results view for the color and size of the nodes, and which property to use as a caption.
A node's label won't be an option for the caption, so if you want the caption to be the label, add a property whose value is the string of the label, and select that as the caption.
I have a query I am working on neo4j making my first queries in Cypher, I noticed that when the graph is generated, when establishing the names of the properties, the generated graph only shows the id, to save this difficulty I noticed that for example for a person node instead of placing the property nom (with this name the problem already mentioned is presented) I put name and in that case if I can see the node, attached image. Why does this happen?
CREATE (Peter:Persona {nombre:'Peter Sagan', fechanac:'26-01-1990', pais:'Slovaquia'})
CREATE (Peter:Person {name:'Peter Sagan', fechanac:'26-01-1990', pais:'Slovaquia'})
I want to be able to establish my own names of nodes and properties and that in the graph view the textual value of the first property appears. How do I do it?
I hope you understand my query from now thank you very much :slight_smile:
The Neo4j Browser UI Guide should be helpful in learning how to use the neo4j browser.
The neo4j browser allows you to change the caption for each node label. If you click the red Persona(1) button at the top of the result panel, you will see several options appear at the bottom, including the available Captions. You can then select the caption you want to use for all Persona nodes.
Click on a node for which node you want to change the view.
Go to the top as shown in the image and click the label
Then you can select the color, size and the caption listed.
I am using Neo4j for the first time. When I am querying nodes, it would only show their name. Would it be possible to show multiple fields beside a name, like age, location, etc..?
If you are using the neo4j Browser, the default Graph tab (in the light-gray vertical panel to the left of the visualization) only supports showing a single value for a node at a time (since there is not much room to display such data when a lot of nodes and relationships are displayed).
But you can see node (and relationship) properties by clicking on the Table or Text tab.
How we can change Property name/Values manually in Neo4j. Which Property should be in centre to show relationships with other nodes.
An example just to elaborate the question
In graph output,How "Tom Hanks" can be replaced with some other property of Tom Hanks.
This is related to the visualizer running in the browser view, and not neo4j itself.
If you check the node labels at the top of the output view, tap on the label related to the thing you want to change (it may also show if you tap on the node in question to give it focus). Now, at the bottom of the window, you should see properties of that node. Tap on the one that you want to show up for nodes of that label in the visualizer.
When I created my graph database in Neo4j, I thought the node label was the same thing as what the node caption would be in the web browser visualizer. Instead, the node captions are set to the first property of the node by default. Is there a way to set the node captions to be the same string as the node labels? I see that there is the graph style sheet where I can change the node captions manually, but I don't know how to set the caption variable equal to the label.
There is a way to use a node label as a caption in the neo4j browser, but there is a caveat (see below).
You can modify the Graph Style Sheet to hard-code the caption for the node. (Click the star in the leftmost vertical panel, click the "Graph Style Sheet" button to see the sheet in a pop-up window, export the sheet to a file, make your changes, and drag-and-drop your edited file onto the "Drop a grass-file here to import" line at the bottom of the pop-up window).
For example, if your node label of interest is Person and its caption is currently the name property, then your style sheet may currently contain something like this:
node.Person {
color: #FFD86E;
border-color: #EDBA39;
text-color-internal: #604A0E;
caption: '{name}';
}
You can change the caption to hardcode the label to "Person", as in:
node.Person {
color: #FFD86E;
border-color: #EDBA39;
text-color-internal: #604A0E;
caption: 'Person';
}
That is all fine; but, in general, a node can have multiple labels -- and the above approach will only display one of those labels for a node. Doing a little experimentation, it seems like the label displayed is the first label that was added to the node.
