# Create a function y(x) with uncertainty
x = linspace(0, 1, 21)
y = np.sin(x * 2.0 * constants.pi)
yerr = np.random.rand(len(y))
# Create an uncertainties array, which has both value and error bar
yarr = uarray(y, yerr)
# Make the plot
fig, ax = plt.subplots(nrows=3)
# uerrorbar has an error bar on each point
uerrorbar(x, yarr, ax=ax[0])
ax[0].set_title('uerrorbar')
# uband is an band encompassing the uncertainty

# They can be combined
