At first this example confused me, because normally

  xticks([1.75,2.0])

w/o the labels will do the right thing, ie put labels on 1.75 and
2.0.  The reason it doesn't in your example is that you are using a
semilogx plot, and thus the default formatter is
ticker.LogFormatterMathtext , which only places labels on the
decades.  This may be considered a bug, wart, or minor annoyance.  As
you note, there is an easy workaround.  

Alternatively, it might be better to change the formatter when there
is a call to set_ticks just as we currently change the locator


    def set_ticks(self, ticks):
        """
        Set the locations of the tick marks from sequence ticks

        ACCEPTS: sequence of floats
        """
        self.set_major_locator( FixedLocator(ticks) )

        self.get_view_interval().update(ticks,0)
        return self.get_major_ticks()
