Hi,

Apparently I'm somehow misusing the functionality of interp1d(.) or does following behavior imply a bug in scipy. A minimum snippet (with plots) to demonstrate the problem:
In []: from scipy.interpolate import interp1d

In []: n= 1000
In []: x, y= randn(n), linspace(0, 1, n)
In []: x.sort()

In []: plot(x, y, lw= 2)
Out[]: [<matplotlib.lines.Line2D object at 0x12E190D0>]

In []: f= interp1d(x, y, 'cubic')
In []: xi= linspace(x.min(), x.max(), n)
In []: plot(xi, f(xi))

Out[]: [<matplotlib.lines.Line2D object at 0x12E20830>]
