Log Message:
-----------
Fixed bug #1889750.
Now an axes will not attempt to determine the default units to use if units have already been determined for a particular Axis.
Previously, by doing this it would override any axis labels set whenever any unit determination calls were made.  This can still happen, but now some of the unneccessary unit determination calls are no longer being made.
