Question about importing data into the dashboard

General

@ErnestoBalestro welcome to the forum!

While I wish I could give you an answer right away, you haven't provided information for anyone to act on.

  1. what device and OS are you running Node-RED on?
  2. what version of Node-RED and node.js are you running (you can get this from the NR startup log)
  3. are you using dashboard v1 or the newer V2?
  4. Please post your flow so people can see what you actually have done.

My guess is that number in the graph is actually a timestamp.

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)

```

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.
