Wulff plot not working

[cedenoruel]

The Bug

The wulff.show() function which normally gives a static plot no longer works.
Instead, it returns <Figure size 576x576 with 0 Axes>
However, wulff.get_plotly() works (which gives an interactive plot).

To Reproduce

!pip install pymatgen
# Import the neccesary tools to generate surfaces
from pymatgen.core.surface import SlabGenerator, generate_all_slabs, Structure, Lattice
# Import the neccesary tools for making a Wulff shape
from pymatgen.analysis.wulff import WulffShape

lattice = Lattice.cubic(3.508)
Ni = Structure(
    lattice,
    ["Ni", "Ni", "Ni", "Ni"],
    [[0, 0, 0], [0, 0.5, 0], [0.5, 0, 0], [0, 0, 0.5]],)
surface_energies_Ni = {
    (3, 2, 0): 2.3869,
    (1, 1, 0): 2.2862,
    (3, 1, 0): 2.3964,
    (2, 1, 0): 2.3969,
    (3, 3, 2): 2.0944,
    (1, 0, 0): 2.2084,
    (2, 1, 1): 2.2353,
    (3, 2, 2): 2.1242,
    (3, 2, 1): 2.3183,
    (2, 2, 1): 2.1732,
    (3, 3, 1): 2.2288,
    (3, 1, 1): 2.3039,
    (1, 1, 1): 1.9235,
}
miller_list = surface_energies_Ni.keys()
e_surf_list = surface_energies_Ni.values()

# We can now construct a Wulff shape with an accuracy up to a max Miller index of 3
wulffshape = WulffShape(Ni.lattice, miller_list, e_surf_list)

# Let's get some useful information from our wulffshape object
print(
    "shape factor: %.3f, anisotropy: \
%.3f, weighted surface energy: %.3f J/m^2"
    % (
        wulffshape.shape_factor,
        wulffshape.anisotropy,
        wulffshape.weighted_surface_energy,
    )
)


# If we want to see what our Wulff shape looks like
wulffshape.show()

Bug confirmed.

@CifLord Are you familiar with this code? If you have time, maybe you could take look?

[CifLord]

Yeah I can take a look, thanks for letting me know!

Made a pull request to fix this. @cedenoruel do you know what version of matplotlib you're using? If its 3.6.0 or higher, its not compatible with the Wulffshape plotter. In any case, the pull request should fix the compatibility issue now

@CifLord @janosh Now, it's working again. Thank you very much.
