I had an answer to a question which was recently migrated to SuperUser. I'm not completely sure why the question was migrated from StackOverflow. Is there a way to get an explanation as to why it was migrated? Is there a way to vote to move it back to StackOverflow?
I think that the question is perfectly appropriate for StackOverflow because it is a question about how to accomplish a particular task in
gnuplot -- which is a scripted plotting utility (i.e. a very special purpose programming language). If this question belongs on SuperUser, then pretty much every other gnuplot question on StackOverflow should be migrated as well.
As a side note, this question was also moved -- presumably in the same time range (and I'm not sure why).
