Looking back through the archives, I found this discussion of manipulating
ticklabels.

I am having the same problem as Eugen, and the suggested solution of using
a.xaxis.get_major_locator().refresh()
to force the creation of the full set of ticklabels doesn't seem to work for
me.
Sample script:
from pylab import *
#ion()
a =axes([0.2,0.2,0.7,0.7])
t = arange(0.0, 2.0, 0.01)
s = sin(2*pi*t)
a.plot(t, s)
a.grid(True)
# matlab handle graphics style
a.xaxis.get_major_locator().refresh()
xticklabels = getp(a, 'xticklabels')
setp(xticklabels, 'color', 'r', fontsize='medium')
setp(xticklabels, dashdirection=0, dashlength=10, dashrotation=90)
#savefig('axprops_demo')
show()
even with a.xaxis.get_major_locator().refresh(), only the first ticklabel
has its position adjusted.
replacing
setp(xticklabels, dashdirection=0, dashlength=10, dashrotation=90)
with code modifying the position
for i in range(len(xticklabels)):
xtp = getp(xticklabels[i],'position')
setp(xticklabels[i],position=(xtp[0],-0.05))
also only effects the first ticklabel.
changes to color and fontsize of the first ticklabel do carry over the full
set of ticklabels, but TextWithDash properties do not carry over.
Uncommenting ion() at the beginning of the script generates the desired
image with offset ticklabels, but requires using interactive mode.
Any help either getting
a.xaxis.get_major_locator().refresh()
to work properly, or to get TextWithDash properties to carry over from the
initial single ticklabel to the full set of ticklabels would be greatly
appreciated.
