I'm making a plot with two axes (axUpper and axLower) that is a bit of a
copy of John's financial plot in
axUpper has it's y axis on the left and axLower has it on the right and
each of these sets of labels has an extraneous bit of a date label on
axUpper has a chunk of 'February' at the point where axUpper and axLower
meet and the axLower labels have an extra bit of '02' at the same spot.
Anyone have an idea of why that might be?
