This cookbook flow will show you what you need to do to join the messages.

[https://cookbook.nodered.org/basic/join-streams](https://cookbook.nodered.org/basic/join-streams)

The dashboard info panel will then explain what format you need for the message you send the dashboard node

You don't need to join them ! - just make sure they have different `msg.topic` set and feed into the same chart .
