Grafana: выделения времени суток на шкале TimeScale
В одном из проектов (умный дом) у меня мониторится температура окружающего воздуха. Но график… ну так себе если честно..
Ну совершенно не понятно не поёрзав мышкой, где день, где ночь.. Решил неказисто,.. но хотя бы уже понятно:
Просто наложив поверх еще один запрос, где вывожу в зависимости от часа суток предопределенные значения.
