Akima interpolator
Fit piecewise cubic polynomials, given vectors x and y. The interpolation method by Akima uses a continuously differentiable sub-spline built from piecewise cubic polynomials. The resultant curve passes through the given data points and will appear smooth and natural.
Parameters: | x : ndarray, shape (m, )
y : ndarray, shape (m, ...)
axis : int, optional
|

Notes
New in version 0.14.
Use only for precise data, as the fitted curve passes through the given points exactly. This routine is useful for plotting a pleasingly smooth curve through a few given points for purposes of plotting.
