  1. Please stop/start node red and then copy the startup log and paste it to a reply.

  2. what nodes did you install?

How do you start node-red?
On a pi you open a terminal and enter ‘node-red’ and node-red will start running outputting information. That is the startup log I want to see.

im using windows and start using command prompt, here is the startup log

Good, that is what I wanted to see. It looks like your gauges are working at this point. Now for a chart you need to add in ui-chart. Have you tried that?

Here is one example of how charts work,

Click on the node id above the error and it will take you to the node showing the error. One of them is called decision tree classifier trainer.

I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
