I am a complete noob at Node-red and could use a little help with tweaking two graphs on my Homey MQTT Node-red Dashboard. I managed to obtain the temperature and humidity values from my sensors and to display them as lines in two graphs. One graph displays the temperature in 6 rooms and the other the humidity in those same 6 rooms. However, I am unable to set the same colour of the lines for the temperature and humidity of the same room in the two graphs (i.e. the legends of the graphs do not match). Please see the screenshots of my Node-red flow and the dashboard. Could someone please explain to me how I can get this done? Thanks in advance!
