Currently Akima is not a valid interpolation method in Pandas. However scipy does have Akima1Dinterpolator. As Pandas uses SciPy for doing interpolation, adding the Akima method to pandas should be easy.

sure, requires scipy >= 0.14.0 though.

It looks like for the pchip interpolate that pandas just does a check to verify that it is there, and otherwise reports that scipy doesn't support it.

I was just doing some work that involved using the Akima interpolation function and it is not working as I would expect. I created a ticket with an example #21276
Any idea what might be going on here?
