[Paraview] Cube axes label format

Mon May 6 16:00:18 EDT 2013

Thanks Gudni,

I've just pushed something to next.

commit 89362b00ececb01765ce4683c4b6d40db4164370
Author: Sebastien Jourdain <sebastien.jourdain at kitware.com>
Date:   Mon May 6 15:55:27 2013 -0400

    Expose CubeAxes Label format to the proxy layer.

    Change-Id: I8af3ddf8ca33c8d27332cc5ae052e1e636388725

You should be able to get it inside the nightly binary by the end the week.

Then you will need to do inside the python shell:

>>> rep = Show(GetActiveSource())
>>> rep.CubeAxesXLabelFormat = "%-#1.4g"

The only thing that you might need to do, is to invalidate the bounds of
the cube axes (by changing your data in some way) to make sure the new
label get generated with the newly set format.
