contourf error

[sarahshi]

Hi Patricio,

Hope this message finds you well. I just wanted to write to alert you of a potential error introduced in the pairwise function. It appears that contour's collections have been modified. I just got a failed pytest after pushing some updates to my code. Find the error and the snippet of code involved attached.

Best, Sarah
