Hello to all
I want to ask what is the default interpolation method of python matplotlib contourf? Where can I find relative documentation? Could someone help me?
Best regards

Hello Sakis,
All of Matplotlib’s contouring functions (contour, contourf, tricontour, tricontourf) use linear interpolation along grid edges. This is not explicitly documented anywhere.
Are there other interpolation options that you would like? I can think of logarithmic as one possibility.

Hello Ian
Another interpolation may come handy in the future. Is it possible to control the interpolation method?
The fact that the current interpolation method is not documented is a pity. I need to reference it in a manuscript…

Hi Sakis,
No, you cannot control the interpolation method, you are stuck with linear for now. It is on my wishlist for future improvements, but this is no help to you now.
To demonstrate that it is linear interpolation I would reference the code, e.g. https://github.com/matplotlib/matplotlib/blob/ea6803254567eaaa9adb027b541a6885d9fa246f/src/_contour.cpp#L1345-L1354 is the C++ interpolation function which is self-evidently linear interpolation. I am not sure if that link is good enough for a manuscript though.

Hello again Ian
I can work with linear, no problem!
Regarding, the reference: The link may not be sufficient. I depend. I guess I may have to find a general reference for the linear interpolation to incorporate in my manuscript.
Thank you very much!

Hi all,
Sakis, are you saying that if the (linear) interpolation scheme was simply mentionned in the relevant docstring (I imagine some place like `matplotlib.axes.contour{f}` or `matplotlib.contour.{Quad}ContourSet`), then it would be enough regarding your need for a reference? I guess that a quick PR to fix what seems to be a small yet quite unfortunate
hole in the documentation anyway would be welcome, would it not?
Best regards,
Adrien
