Answer 1

In order to draw a line with the linewidth in data units, you may want to have a look at this answer.

It uses a class data_linewidth_plot which closely resembles the plt.plot() command's signature.

l = data_linewidth_plot( x, y, ax=ax, label='some line', linewidth = 1, alpha = 0.4)

The linewidth argument is interpreted in (y-)data units.
