[Paraview] color isosurface using another data file

[Yongcheng Zhou]

Thanks  a lot Cory - you saved my day!

While this must be trivial for experienced paraview users, I still 
want to share the detailed steps: (1) load two files one by one; make sure 
they have the same topology and different scalar array names; (2) 
select both files in the pipeline window by using Shift key and 
clicking two file names; (3) with two files selected, go to Filters 
and choose Append Attributes; This creates a new object AppendAttributes1; 
(4) using this new object to create contour and color it. Now there are 
options in Contour by and Coloring when creating contour. Choose the array
at your choice.

Thanks again.
