Centering Tick Labels BETWEEN Tick Marks

Take a look at



From your references, I have been mostly able to figure out how to do it. Thank you.
So far, I have:

create transformation with x in data coords and y in axes coordinates

transLabels = matplotlib.transforms.blend_xy_sep_transform(
ax.transData, ax.transAxes)

get major locator and usurp major formatter for custom positioning

major_locator = ax.xaxis.get_major_locator()

major_formatter = ax.xaxis.get_major_formatter()

create custom text labels centered between major tick marks

major_locs = major_locator()

for i in range(1,len(major_locs)):
x_last,x = major_locs[i-1],major_locs[i]
ax.text(0.5*(x+x_last), -0.04, major_formatter(x, i),
transform=transLabels, horizontalalignment=‘center’)

When “zooming around” an interactive plot, however, my custom labels get pushed

off into the margins. I’m guessing I need to put them in a clip box somehow. Any hints?
