3#  COMPONENT: ResultViewer - plots a collection of related results
4#
5#  This widget plots a collection of results that all represent
6#  the same quantity, but for various ranges of input values.  It
7#  is normally used as part of an Analyzer, to plot the various
8#  results selected by a ResultSet.
