Problem using two-dimensional interpolation. Result looks bad

[player1682]

I suggest you find a more recent tutorial. From scipy documentation for interpolate.Rbf

https://docs.scipy.org/doc/scipy/referen...e.Rbf.html

Rbf is legacy code, for new usage please use RBFInterpolator instead.

It looks like you want change the axes for you plot. Try this:

fnew=newfunc(ynew, xnew)

Thanks for the advice I will start reading documentation on interpolate.Rbf.

I have tried swithching X and Y as you suggest. I get the attached figure. It has to be something else. I hope it has to do with the obsolete code.

Edit:

newfunc=scipy.interpolate.Rbf(resulttokenX2.astype('float'), resulttokenY2.astype('float'), resulttokenF2.astype('float'), function='linear')

returns the same values
