Hi everybody, I'm pretty new to NodeRed. I have a problem with making graph with data stored. My data are in Json format like :{"t":"2018-12-12T15:00:00.000Z","temp_in_cooling":"320.00"}. i Can make graph using directly these data by means of $.feeds.{"x":t, "y" :temp_in_cooling} with the exchange…
