In most cases, MD line cuts should have axes and units reported w.r.t their origin workspace. I generated a work around for this issue here http://trac.mantidproject.org/mantid/ticket/8104, but there should be a good way to access this information on the generated MDWorkspaces.

The following script illustrates the problem. The generated plot lines should completely overlap.

#!python
CreateMDWorkspace(Dimensions='2',EventType='MDEvent',Extents='-10,10,-10,10',Names='Q_lab_x,Q_lab_y',Units='A,B',OutputWorkspace='test')
FakeMDEventData(InputWorkspace='test',UniformParams='1000',PeakParams='100000,0,0,1')

line_md = BinMD(InputWorkspace='test',AxisAligned='0',BasisVector0='X,units,0.888154,0.459545',BasisVector1='Y,units,-0.459545,0.888154',Translation='-4.93562,-2.3918',OutputExtents='0,9.61632,-0.1,0.1',OutputBins='100,1')
save_path = "/Users/spu92482/Desktop/line_md.nxs"
SaveMD(Filename=save_path, InputWorkspace=line_md)
reloaded_line_md = LoadMD(Filename=save_path)
plotMD([line_md, reloaded_line_md]) # Should be the same!!!!
