Wrong xlim for bar plot with just one bin

[janpipek]

In this degenerate case, xlim for a bar matplotlib plot is set to (0, 1):

import matplotlib.pyplot as plt
from physt.histogram1d import Histogram1D
h = Histogram1D([0, 10], [1])
h.plot()
plt.show()

However, this works:

import matplotlib.pyplot as plt
plt.bar([0], [1], [10], align="edge")
plt.show()
