[pyngl-talk] double x-axis labels in Ngl.xy

[Mary Haley]

Matt,

You still need to use the tmXBMode / tmXBLabels / tmXBFormat resources, and
then you can use the string formatting capability in Python.

lats = [-30,   -20.41  , -9.21,   2.589, 14.316]
lons = [125.0, 143.123, 158.91, 173.689, 188.71]
tmXBLabels = (["{:0.2f}~C~{:0.2f}".format(lats[i],lons[i]) for i in
range(len(lats))])
print(tmXBLabels)

This should produce:

['-30.00~C~125.00', '-20.41~C~143.12', '-9.21~C~158.91', '2.59~C~173.69',
'14.32~C~188.71']

which you can use as your argument to xmXBLabels.
