Crashes consistently on Sankey diagrams

[graphadvantage]

Seems very unstable in the upgraded desktop and using Neo4j 4.2+. Many of the chart types don't work or cant render labels properly.

Do you have any sample queries that you can share which are crashing the app?

[graphadvantage]

Using MacOS Catalina 10.15.7
Neo4j 4.2.3, Desktop 1.4.1
Updated Chart App 1.0.7, all permissions granted

encounter problems right away
having created a test dashboard, clicking on Help crashes the app. Restarting the app does not recover the dashboard, and it has to be recreated.

For Sankey, and Vertical Sankey

MATCH (actor:Person)-[:ACTED_IN]-(m:Movie)-[:DIRECTED]-(director:Person)
WITH actor.name AS from, director.name AS to, COUNT(DISTINCT m) AS value
RETURN from,to,value ORDER BY value DESC

App crashes and dashboard is lost

Chord does work, but seems to truncate the data

The bar charts seem to have problems rending axis labels properly:

MATCH (n)
RETURN 1 AS index, labels(n)[0] AS key, COUNT(n) AS value

Line Charts not labeled correctly, and disappear when expanded, but the hover tips still render, some kind of canvas issue?

MATCH (n:Movie)
RETURN (n.released) AS key, COUNT(n) AS value ORDER by key

Radar charts don't seem to work right, crashes the app

MATCH (n:Movie {title:"The Matrix"})<-[:ACTED_IN]-(actor)
RETURN actor.name AS key, n.released-actor.born AS value ORDER by key

There also seems to be some issue with saving data for the dashboards in general.
I have yet to be able to load a saved dashboard, maybe there's a files permissions issue.

Perfect, thanks. When the app crashes can you open up the Developer > Developer Tools and check for errors?

Sankey

It looks like the Sankey charts don't like circular references. The error is thrown by the underlying library so it can't be caught and turns the screen white which is frustrating. If I use this query instead it works:

MATCH (actor:Person)-[:ACTED_IN]-(m:Movie)-[:DIRECTED]-(director:Person)
WHERE actor <> director
WITH actor.name AS from, director.name AS to, COUNT(DISTINCT m) AS value
RETURN from, to, value ORDER BY value DESC

I've added a check to remove circular references.

Help Page

Same problem with the Help page - for some reason the library supplies some invalid styles to a Transition component which throws an error - I've disabled animation which will hopefully solve the issue.

Bar/Line labels

This seems to work fine for me here so there must be some rendering issue somewhere. I'll see if I can replicate it with another browser.

Issues Saving & Opening

Are you opening the app in Neo4j Desktop?

If so, when the app opens it will look for graphpanel-dashboards.json and graphpanel-queries.json file in the current active project (the project with the current active database). Every time you change something, this file should be updated. If you switch active databases then the file may be saved to another project. When the app loads, it checks for files with these names in the active project and loads them into memory. This is done by a GraphQL query - so there may be an error message in the Network tab of Developer Tools.

If you're not using Neo4j Desktop then the information is saved to local storage in the browser.

Feel free to drop me an email on adam at neo4j.com or send me a message on the Slack channel if you want to into more depth on this

Hi Adam - Thanks for taking a look. I updated using your latest build - still seeing issues. I am launching through the desktop. Help is crashing the app, and updating the Sankey queries to remove the circular references didn't fix the crash issue. I don't see anything coming through in the logs that was informative. I am not seeing the .json files being created in /project folders.

got the same issues as the original author regarding help and missing .json files.
