TypeError when plotting stacked bar chart with decimal #10788
Description
Bug report
Bug summary
When plotting bar graph, TypeError exception is raised if values for bar bases are Decimal types.
Code for reproduction
from decimal import Decimal
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
x = list(range(10))
y = [Decimal(x) for x in range(10)]
bar1 = ax.bar(x, y)
bar2 = ax.bar(x, y, bottom=y)Actual outcome
Traceback (most recent call last):

TypeError: ufunc 'isfinite' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''
Expected outcome
No exception is raised, bar2 line behaves the same way it would if y contained ints or floats.
