Bug with nmin in hist()

[AstroRobin]

There seems to be a bug due to the addition of the nmin parameter in hist(). Minimum working example:

x=np.random.normal(2,1,10000)
y=np.random.gamma(4,0.5,10000)
z=np.cos(x*y)

fig, axes = splt.subplots()

splt.hist([x]*2,v=[y]*2,vstat=['median','mean'],plabel=['running median','running mean'],color='r',
linestyle=['dotted','dashed'])

plt.show()
