It used to work, but since the latest update or so, when I click on the graph icon of any device that have temperature sensor, it returns to the main page of the app.
Depending on the language your phone is set to, that may be the issue. See Histogram lost?

I reordered them and histogram works. (English first)
I reordered them back again and histogram stopped working. (Portuguese first)
