With 2 fields it works fine but not with 6. What do I need to change, in order to read more than 2 fields successfully?

I need to combine a bunch of different channels to make a dashboard for sensors all around my house!

Temperature corresponds to what I named my field in my channel. You can name the field what you want, but the name will have to match the code.

Think it was too late when I did this, too late for scrolling 🙂

Thanks that solved my problem!
Greetings from Austria

Glad that the example worked for you. In the example code, the box looks like it is cutting off 3 lines that need to be scrolled to see.

title(‘Temperature and Humidity Synchronized From Two Channels’)
xlabel(‘Temperature and Humidity in Natick, MA’)
legend(‘Temperature’,’Humidity’)

I hope that helps.

How did you get the legend (Temperature, Humidity), they don’t show up with this code (at least for me). am I missing something?
Thanks!
