Node Graph isn't Showing Directional Arrow

[dooley]

• What Grafana version and what operating system are you using?
  Free v12.1.1

• What are you trying to achieve?
  I’m trying to create a node graph to show data lineage.

• How are you trying to achieve it?
  I’m achieving it using MySQL.

• What happened?
  I am able to graph the nodes and edges, however the edges have no directional arrow. This occurs with both complex and simple datasets.

• What did you expect to happen?
  I expect edges to have arrows to show direction.

• Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
  No errors.

• Did you follow any online instructions? If so, what is the URL?
  I have been using the node graph documentation. Node graph | Grafana documentation

Simple example:

Expected:

Any help is appreciated, thank you.

nodeGraph with mysql

It works for me. Grafana 8.5.2 - you don’t need a real tables for simple testing: [image] Start with this simple example and if it works fine, then add more fields. Fields are/have been case sensitive, so keep in mind mainstat!=mainStat. You can starts with nodes only, maybe string edge id is a problem.

Hey @jangaraj,
The string edge id was the problem thank you!
