# ----------------------------------------------------------------------------
#  CLASSES: nightly
#
#  Test Case:  vector.py
#
#  Tests:      vector    - 3D rectilinear, unstructured single domain
#              plots     - vector, plus interactions with some operators.
#
#  Defect ID:  '4954
#
#  Programmer: Hank Childs
#  Date:       June 2, 2004
#
#  Modifications:
#    Jeremy Meredith, Thu Jun 24 12:58:06 PDT 2004
#    Set the vector origin explicitly for some cases because I changed the
#    default to Tail.
#
#    Jeremy Meredith, Tue Jul  8 12:54:58 EDT 2008
#    Added test for new limit to original cells/nodes only.
#
#    Mark C. Miller, Wed Jan 20 07:37:11 PST 2010
#    Added ability to swtich between Silo's HDF5 and PDB data.
#
#    Cyrus Harrison, Thu Mar 25 09:57:34 PDT 2010
#    Added call(s) to DrawPlots() b/c of changes to the default plot state 
#    behavior when an operator is added.
#
#    Kathleen Biagas, Tue Nov 29 10:41:39 PST 2022
#    Replace obsolte 'colorByMag' vector att with 'colorByMagnitude'.
