Plotting Bug from CutMD

[OwenArnold]

Here's the issue as reported by Russell

#Set things up
hkl = LoadMD(Filename='C:\Russell\Software\Mantid\VATES\VATESdemoSSC15\Templates\FeDataset.nxs' ,FileBackEnd=1)

#Create projections (equivalent of proj in Horace):
projection = CreateEmptyTableWorkspace()
projection.addColumn("double", "u")
projection.addColumn("double", "v")
projection.addColumn("double", "w")
projection.addColumn("double", "offsets")
projection.addColumn("str", "type")
projection.addRow([1, 1, 0, 0, "r"])
projection.addRow([1, -1, 0, 0, "r"]) 
projection.addRow([0, 0, 1, 0, "r"]) 


#QE slice and look at it in the sliceviewer
horace_style = CutMD(hkl,projection, [-3,0.05,3], [0.9,1.1], [-0.1,0.1], [0,4,300], NoPix=True, CheckAxes=False)
sv=plotSlice(horace_style)
sv.setNormalization(2)#set norm to number of events
sv.setXYDim(0,3)#Choose the correct plot axes (0th and 3rd in Python!)
sv.setColorScaleMin(0)#set colour scale limits
sv.setColorScaleMax(1)
sv.setXYLimits(-2,2,0,200)

#If you try to make a 1d cut along (1,1,0), integrating in energy, direct in line mode in the sliceviewer, something weird happens to the integration box – it becomes a trapezium… Nevertheless, if you manage to make the 1d cut this way, and then plotMD, the result has the correct x-axis of (H,H,0).

horace_1d=CutMD(hkl,projection, [-2,0.05,2], [0.9,1.1], [-0.1,0.1], [33,40], NoPix=True, CheckAxes=True)
pm=plotMD(horace_1d,error_bars=1,normalization=mantid.api.MDNormalization.NumEventsNormalization)

#The plotMD here has axes of (H,0,0), with the “correct” (H,H,0) not available as an option.
