Cannot pass norm argument to hist2d

[Kinya Toride]

Description

There is an error message when I pass a norm argument to hist2d.

Steps to reproduce

import numpy as np
import proplot as pplt
import matplotlib as mpl

N = 500
state = np.random.RandomState(51423)
x = state.normal(size=(N,))
y = state.normal(size=(N,))

fig, ax = pplt.subplots()

_, _, _, m = ax.hist2d(x, y, norm=mpl.colors.LogNorm())
fig.colorbar(m)

      6 fig, ax = pplt.subplots()
      8 _, _, _, m = ax.hist2d(x, y, norm=mpl.colors.LogNorm())

ValueError: Invalid vmin or vmax

Equivalent steps in matplotlib

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

N = 500
state = np.random.RandomState(51423)
x = state.normal(size=(N,))
y = state.normal(size=(N,))

fig, ax = plt.subplots()

_, _, _, m = ax.hist2d(x, y, norm=mpl.colors.LogNorm())
fig.colorbar(m)
