In a more recent version (`2022.3.0`), both 1D and 2D case return the same `ValueError` with a relatively clear message `x and y arrays must have at least 2 entries`.

I'm still proposing that any valid code with `sel` should behave the same with `interp`, and thus that `interp` should work when a dimension has a single entry. But this is a low priority issue with easy workarounds.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,666270493
