I have this Cypher query:
MATCH (i:Issue {name:"SN-229"})-[d:ON_DATE]->(s:Stage)
RETURN i,(MAX(d.long)-MIN(d.long)+1) AS Days,s
and I get these results in the Neo4j Browser's Text view
Which are the answers I want.
But when I view the result in the Neo4j Browser's Graph view, it insists on displaying the individual dates in the relationships!?!?
What query could I write to show me this "ideal" Graph view (the displayed dates are the MIN(d.long) dates) or at least just display the relationship with the MIN date?
This query will return all of the required info for my ideal Graph view, but again, it insists on displaying all of the relations (and I don't know how to modify the caption for the relationship, via the query, to add the 'X Days' to the relation's displayed date):
MATCH (i:Issue {name:"SN-229"})-[d:ON_DATE]->(s:Stage) RETURN i,MIN(d),(MAX(d.long)-MIN(d.long)+1) AS Days,s
When the option "Connect result nodes" is checked, Neo4j browser will connect the resultant nodes in the graph visualization mode when a connection between these nodes exist.
To disable this behavior you should go to the section "Graph Visualization" of Neo4j Browser Settings and uncheck the option "Connect result nodes" as show in the image below:

I have built my first graph from real data using Neo4j Browser version 4.0.3, server version 3.5.6 and am getting query results.
For example, this query returns 112 records:
MATCH (pls:PLS)-[:LOCATED_AT]->(pl:PL)
WITH pl, count(pls) AS num_pls
WHERE num_pls > 20
RETURN pl.id, pl.node_name, num_pls
However, I cannot visualize my results because there is no graph button in the left margin of the browser results pane -- only the "Table", "Text", and "Code" buttons.
I've been searching the doco and Googling, but nothing I've found mentions this issue.
A query has to RETURN some nodes, relationships, and/or paths in order for the Browser to show a "Graph" visualization of them.
Your query is only returning a couple of properties and a calculated value.
I am new to neo4j and I am working on PoC. I succeeded in adding nodes and relations using import queries. But I can't find Rows tab to view query result data in tabular format. I can see Tabs Graph, Table, Text and code. I want Rows option also available in tabs. Please let me know if I have missed anything
What you are seeing is the way the browser is designed to work. The Table tab is returning your results in a tabular format. However, if a table column's value is a map (or a node or relationship), then the values in that column will be presented as a map (which looks like a JSON object). Also, if a column's value is a list, it will be presented as an array. Scalar column values (like numbers and strings) will be presented more in the way that you were probably expecting.
So, for example, the Table tab for the result of this query:
RETURN {a:1, b:2} AS map, [1,2,3] AS list, 123 as number, "abc" as string;
would look like this:
I have a scenario to verify the Sort&Filter functionality for Mobile App in Android.
Scenario:
Search for Item
Search Result Apper
Sort&Filter with some criteria
Have to Verify that Sort&Filter is applied correctly
Here results are added to RecyclerView.
As per RecyclerView/appium functionality, all the items are not loaded into view. Only visible Items are loaded into the view Hierarchy.
When I scroll Up the Linear Layout Indexes are re-arranged. I could not able to get all the Items.
Could you kindly provide me any sample scenario of this kind?
Or How can we achieve this kind of scenarios in Real Automation while working on the project?

Issue with Android as You stated is that it "sees" only what is visible on screen. I have similar issue, so I had to go deeper into element and fetch text. In your case I would do following:
1. Search Result Appear:
- fetch all visible elements, input search, fetch again -n results containing search result. Eg. if input 'beer' there should be eg. 4 elements with text containing "beer". Put elements in list and iterate:
List <MobileElement> listElements = driver.findElements(By.id("someId"));
for(MobileElement el : listElements){
if(el.getText().equalsIgnoreCase(expected)){
// do some validation //
}
}
Search Result Appear:
input exact value that will return unique, one result so You can easily count.
Sort&Filter with some criteria
remember initial values in items (text like 'Budweiser beer'), do some filtering / sorting, and check text in first element if is changed and if correct logic is applied (eg. sort desc.)
Have to Verify that Sort&Filter is applied correctly
think I answered in 3.
Basically:
'pick' text from items store them,
do some action (search, sort, filter),
'pick' newly changed items caused by 2. step, store them,
compare (depending on what You need...),
To get all items you have to swipe and store them in list.
my nodes have the following order in GrapheneDB neo4J hosted database:
<id>:3 human_date:Wednesday, July 5, 2017type:painuuid:7c74a49d-f102-4825-914b-87dcc88d339bvalue:Emptinessepoch_utc_i:1499285499
The input of the JSON object is I first create the node with the value, and then set properties: {uuid, epoch_utc, human_time}
It's hard to use the graphical UI to see different nodes because only human_time is displayed...and that is often the same for multiple nodes. I would prefer to see type or value
You can change the properties that were picked by Neo4j Browser to be displayed as captions.
Just click at the top of the window on a Label tag, and once selected, change the caption at the bottom to type or value.
For more advanced styling, like displaying multiple captions, you can edit the Graph Style Sheet (.grass file). Just enter :style in Neo4j Browser, click on the download icon, edit and upload the file back and the changes will be reflected.
You can read more on Neo4j Browser styling here.
I would like to compare mysql and neo4j and for that I have dumped a lot of data in neo4j as well mysql.
now the problem is In neo4j I cannot execute a query which returns more than 1000 rows therefore I cannot see the time of execution of that query.
In mysql I can eaily see the execution time in the console.
Also I would like to see a complete graphical view of all my nodes in Neo4j. Is it possible?
The limitation to 1000 result is a safety net withing Neo4j browser. Otherwise very long results might mess up your web browser in terms of memory and/or CPU for rendering.
To get the full plain results for comparison send your query as REST request using e.g. cURL. See http://docs.neo4j.org/chunked/stable/rest-api-transactional.html#rest-api-begin-and-commit-a-transaction-in-one-request for an example of the request, make sure you're using Accept and Content-Type header set to application/json. Additionally you might stream the result as documented at http://docs.neo4j.org/chunked/stable/rest-api-streaming.html.
There is a setting that limits the number of rows displayed, by default it's 1000. To change this setting Open Neo4j Browser -> Go to Settings and in the Graph Visualization section you can find Max Rows. You can change this to fit your needs. Also in this section another property can be found Initial Node Display - property that limit number of nodes displayed on the first load of the graph visualization.
