You can access the minor tick labels and minor tick labels by getting
a list of the minor ticks and accessing the label attribute

  minlabels = [tick.label1 for tick in ax.xaxis.get_minor_ticks()]

The tick attributes are 

      tick1line  : a Line2D instance
      tick2line  : a Line2D instance
      gridline   : a Line2D instance
      label1     : an Text instance
      label2     : an Text instance
      gridOn     : a boolean which determines whether to draw the tickline
      tick1On    : a boolean which determines whether to draw the 1st tickline
                   (left for xtick and bottom for yticks)
      tick2On    : a boolean which determines whether to draw the 2nd tickline
                   (left for xtick and bottom for yticks)
      label1On    : a boolean which determines whether to draw tick label
      label2On    : a boolean which determines whether to draw tick label

which is also documented at
http://matplotlib.sf.net/matplotlib.axis.html#Tick .  The difference
between label1 and label2 is for left and right labeling for yticks,
and top and bottom labeling for xticks.

You can then call set on the list of labels to set the rotation,
etc...

Hope this helps.

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.

Yes, currently the pylab interface manipulates the current mappable
and colorbar is a pylab only construct.  These features are slated to
be ported into the object interface, where the current mappable will
likely be a figure property and the colorbar will be a figure method.

Glad you found the workaround for the time being...
