Hexagonal limits

    Available with ``mpltern>=1.0.0``

Suppose we would like to crop or expand the following gray-shaded region.

.. plot::
    :context: reset
    :include-source: false

    import numpy as np
    import matplotlib.pyplot as plt
    from mpltern.datasets import get_spiral

    ax = plt.subplot(projection='ternary')
    ax.plot(*get_spiral(), color="k")
    points = np.array([
        [0.7, 0.1, 0.2],
        [0.7, 0.2, 0.1],
        [0.2, 0.7, 0.1],
        [0.1, 0.7, 0.2],
        [0.1, 0.2, 0.7],
        [0.2, 0.1, 0.7],
    ])
    ax.fill(points[:, 0], points[:, 1], points[:, 2], color="0.6")

    ax.set_tlabel("T")
    ax.set_llabel("L")
    ax.set_rlabel("R")

The region is defined as the intersect of :math:`t \in [0.1, 0.7]`,
:math:`l \in [0.1, 0.7]`, :math:`r \in [0.1, 0.7]`.

.. plot::
    :context:
    :include-source: false

    ax.axtspan(0.1, 0.7, color="C0", fc="none", hatch="....")
    ax.axlspan(0.1, 0.7, color="C1", fc="none", hatch="....")
    ax.axrspan(0.1, 0.7, color="C2", fc="none", hatch="....")

Using `set_ternary_lim`, we explicitly specify the min and the max values
for all the ternary axes.

    ax.set_ternary_lim(

    # For a hexagonal plotting region, it may be better to put the axis labels on
    # the sides (either "tick1" or "tick2") rather than the default "corner" to
    # avoid confusion.

    ax.laxis.set_label_position("tick1")
    ax.raxis.set_label_position("tick1")

We can also set the min and the max values of each ternary axis one by one.
