Will clear this up with only top topics.

pattern1: looking for regions of time where some color is all negative/positive

pattern2: looking for regions where some pattern1 switches from pos/neg to neg/pos (or vice versa)

round about 2002, program analysis jumped neg to pos
requirements is mostly neg since 2002

now if cites per year were effected by the pos/neg of the above, that would be interesting...
