Rotate minor tick labels

Hi :

I hava a plot with mayor and minor ticks and
formatters. I want to rotate the labels of both the
mayor and minor ticks. I tried with the following
code:

#...
ax.xaxis.set_major_locator(major)
ax.xaxis.set_major_formatter(fmt_ma)
ax.xaxis.set_minor_locator(minor)
ax.xaxis.set_minor_formatter(fmt_mi)
labels = ax.get_xticklabels()
pylab.set(labels, rotation=30, fontsize=10)

However, only the mayor labels are rotated. How can I
rotate both the major and minor labels?

Regards,
Alejandro.
