def rotateTickLabels(ax, rotation, which, rotation_mode="anchor", ha="right"):

    """ Rotates the ticklabels of a matplotlib Axes
19
20
    Parameters
21
    ----------
22
    ax : matplotlib Axes
23
        The Axes object that will be modified.
24
    rotation : float
25
        The amount of rotation, in degrees, to be applied to the labels.
26
    which : string
27
        The axis whose ticklabels will be rotated. Valid values are 'x',
28
        'y', or 'both'.
29
    rotation_mode : string, optional
30
        The rotation point for the ticklabels. Highly recommended to use
31
        the default value ('anchor').
32
    ha : string
33
        The horizontal alignment of the ticks. Again, recommended to use
34
        the default ('right').
