If you are talking about the Ui-gauge, you send it data From another node. If that is not the case please explain what you want to do a bit more

You can use the `msg.ui_control` property to modify the configuration of some ui nodes. What properties you can modify, and how to do it, is documented here: [https://github.com/node-red/node-red-dashboard/blob/master/config-fields.md](https://github.com/node-red/node-red-dashboard/blob/master/config-fields.md)
