I want to make a facet figure with Linear and Polynomial regression in Altair. Stacking together scatter and regression plots seems understandable. However, adding additional polynomial analysis seems problematic. I cannot display the result. I was trying to go around by making a degree list for 1, 3, and 5 as in Altair Gallery, and I was unsuccessful again.
