mpl_toolkits.axisartist.AxisArtistHelper¶AxisArtistHelper should define following method with given APIs. Note that the first axes argument will be axes attribute of the caller artist.:
# LINE (spinal line?)
def get_line(self, axes):
    # path : Path
    return path
def get_line_transform(self, axes):
    # ...
    # trans : transform
    return trans
# LABEL
def get_label_pos(self, axes):
    # x, y : position
    return (x, y), trans
def get_label_offset_transform(self,                 axes,
        pad_points, fontprops, renderer,
        bboxes,
        ):
    # va : vertical alignment
    # ha : horizontal alignment
    # a : angle
    return trans, va, ha, a
# TICK
def get_tick_transform(self, axes):
    return trans
def get_tick_iterators(self, axes):
    # iter : iterable object that yields (c, angle, l) where
    # c, angle, l is position, tick angle, and label
    return iter_major, iter_minor
Fixed(loc, nth_coord=None)¶Helper class for a fixed (in the axes coordinate) axis.
nth_coord = along which coordinate value varies in 2d, nth_coord = 0 -> x axis, nth_coord = 1 -> y axis
get_axislabel_pos_angle(axes)¶label reference position in transAxes.
get_label_transform() returns a transform of (transAxes+offset)
