from dust_extinction.grain_models import C11

fig, ax = plt.subplots()

lam = np.logspace(np.log10(1.0/ext_model.x_range[1]),
                  np.log10(1.0/ext_model.x_range[0]),
                  num=1000)
x = (1.0 / lam) / u.micron

# define the extinction model
ax.plot(lam,ext_model(x),label=ext_model.__class__.__name__)

ax.set_xlabel(r'$\lambda$ [$\mu m$]')
