Hi Nathan,
Did you ever solve this problem?
I have the same problem with OH3.1.4 milestone trying to display a weather meteogram. As you said, it was oh-so simple in OH2, 1 line of code. Tbh, I don’t think Matt Skinah really understood what you were asking judging by the questions he asked & his answers.
Isn’t is frustrating that now in November, one still can’t do a simple thing like this?!!
I have posted my problem a few days ago but no replies yet..
