Answer 1

For text near your line as in this example use:

vline_value = 3

fig, ax = plt.subplots(figsize=(10,10))
ax.axvline(x=vline_value, ymin=0, ymax=1) 
x_bounds = ax.get_xlim()
ax.annotate(s='vline_value', xy =(((vline_value-x_bounds[0])/(x_bounds[1]-x_bounds[0])),1.01), xycoords='axes fraction', verticalalignment='right', horizontalalignment='right bottom' , rotation = 270)
fig.savefig('example')
