"""
Adjust the plotting range of two y axes to align the origins with
the position.
Parameters
----------
ax1 : matplotlib.axes.Axes
First axis object of matplotlib.
org1 : float
Origin of first axis to be aligned.
ax2 : matplotlib.axes.Axes
Second axis object of matplotlib.
org2 : float
Origin of second axis to be aligned.
pos : float or None, optional
Relative position to align the origins [0 < pos < 1].
When pos is None, the origins are aligned to the middle of them.
Returns
-------
Raises
------
TypeError
If 'ax1' and/or 'ax2' are not the Axes object of matplotlib.
ValueError
If 'pos' is less than or equal to 0, or more than or equal to 1.
Examples
--------
>>> import matplotlib.pyplot as plt
>>> from mpl_axes_aligner import align
>>> fig = plt.figure()
>>> ax1 = fig.add_subplot(111)
>>> ax2 = ax1.twinx()
>>> ax1.set_ylim(-1.0, 0.0)
(-1.0, 0.0)
>>> ax2.set_ylim(0.0, 1.0)
(0.0, 1.0)
>>> align.yaxes(ax1, -0.3, ax2, 0.3, 0.5)
>>> ax1.get_ylim()
(-1.0, 0.4)
>>> ax2.get_ylim()
(-0.4, 1.0)
