[Paraview] Temperature visualisation

[Guido Staub]

OK, I did the following  (in this example I reduced the datasets) and 
it seems to work:

<Xdmf>
	<Domain>
		<Grid GridType="Uniform">
<Topology Type="Polyvertex" Dimensions="2 2 1"> </Topology>
<Geometry Type="X_Y_Z"> 
<DataItem DataType="Float" Precision="4" Dimensions="1 2 2" 
Format="HDF">
			test.h5:/bands/latitude
			</DataItem>
<DataItem DataType="Float" Precision="4" Dimensions="1 2 2" 
Format="HDF">
			test.h5:/bands/longitude
			</DataItem>
<DataItem DataType="Float" Precision="4" Dimensions="1 2 2" 
Format="HDF">
			test.h5:/bands/height
			</DataItem>
</Geometry>

<Attribute Type="Scalar" Name="Temp" Center="Cell">
<DataItem DataType="Float" Precision="4" Dimensions="4 1" Format="HDF">
			test.h5:/bands/temp
			</DataItem>
</Attribute>
		</Grid>
	</Domain>
</Xdmf>

But this means that I have to put the temperatures into a 4x1 dataset 
in this example. Or in the "real" case into a 58081x1 dataset. Copy/
paste will take a while.
Guess that this is a hdf related issue.

Thanks all!
