I think since the recent version of PyQtGraph lines only render if they have no NaNs. I see this by printing to the console the contents of data in lasagna.ingredients.lines.plotIngredient. When there are any NaNs it plots nothing. Seems like this bug: pyqtgraph/pyqtgraph#1057

Suggests that PyQt5 version 5.13.1 is bad but 5.13.0 is ok (pyqtgraph/pyqtgraph#1011). I see the problem with 5.14.1

Confirmed. You can side-step this issue by doing:

pip uninstall pyqt5
pip install pyqt5==5.13.0

Workaround for plotting data containing NaNs
75a1e6f 
Data containing NaNs doesn't render properly with the current versions
of PyQtGraph (0.11.0rc0) and PyQt (5.14.x). This commit adds a function
to work around this which is used in the distance detector.
