This appears to be a bug in your code
xmajorLocator = MultipleLocator(0.3)
xmajorFormatter = FormatStrFormatter('%d')
You are telling it to format the numbers as integers. Try
xmajorFormatter = FormatStrFormatter('%1.2f')

This is a problem with matplotlib but I don't have a quick fix for
you. I'll look into it more when I get some time. For now, sharing
the same tick locator between multiple axes is not recommended, though
I understand this is a desirable thing to be able to do. You can make
two identical locators, however, and shouldn't have troubles, which if
I understand you correctly, is what you observe.
