      # return locs, labels where locs is an array of tick locations and
      # labels is an array of tick labels.
      locs, labels = xticks()

      # set the locations of the xticks
      xticks( arange(6) )

      # set the locations and labels of the xticks
      xticks( arange(5), ('Tom', 'Dick', 'Harry', 'Sally', 'Sue') )

    The keyword args, if any, are :class:`~matplotlib.text.Text`
