I was suggesting:
plt.axvline(1, ymin=1, ymax=4, trans=plt.gca().transData)
plt.axvline(3, ymin=2, ymax=6, trans=plt.gca().transData)

when I got the following message :
TypeError: type object got multiple values for keyword argument

In fact, despite the doc tells axvline accepts the transform keyworg
argument, there is no special handling of this kwarg in axvline code (in There is a problem since axvline code (and axhline and
ax*span too I suppose) add a transform kwarg before adding the line to
the axes...
