Auto update, Sorting and Labels

Hi guy´s

New to grafana, but excellent system :slight_smile:
Have a few questions to you guy´s that knows what you are doing

  1. According to picture, where can i put in labels for the sensors, they all correspond to different places, so it would be nice to be able to put a label for each one like (sensor1, In the city)
  2. How can i sort these, they are in the order from the Mysql DB, is there any sort function in grafana?
  3. Last question, can you set this to be continusly uppdated and send this info every xx min so that the snapshot.raintank also is updated??
