def add_colorbar(im, *, aspect=20, pad=0.5, **kwargs):

r"""Add a vertical color bar to a plot.

Parameters

----------

im : ScalarMappable

The output of `sfs.plot2d.amplitude()`, `sfs.plot2d.level()` or any

other `matplotlib.cm.ScalarMappable`.

aspect : float, optional

Aspect ratio of the colorbar. Strictly speaking, since the

colorbar is vertical, it's actually the inverse of the aspect

ratio.

pad : float, optional

Space between image plot and colorbar, as a fraction of the

width of the colorbar.

.. note:: The *pad* argument of

:meth:`matplotlib.figure.Figure.colorbar` has a

slightly different meaning ("fraction of original

axes")!

\**kwargs

All further arguments are forwarded to

:meth:`matplotlib.figure.Figure.colorbar`.
