As the old proverb goes:
"Give a man a fish and you feed him for a day. Teach a man to fish
and you feed him for a lifetime."
You seem to have a grave misunderstanding of what complex numbers are
and how they are represented. I highly recommend you brush up on your
knowledge. Said links should be sufficient for you to correct your
own mistakes.

Unfortunately, this plot does not indicate how to interpret the data I
am reading. Moreover, you did not supply the means of how you created
the graph with both the script or the source data. On top of that, I
have no idea how the data was captured or what the expected result
should be. There are a lot of holes here when it comes to the simple
question: "why this?"
Please take the time to read:

Please, don't forget to perform "Step 6" before mailing the list for help.

Think of this as a learning opportunity as to both learn and teach
others. Feel free to complete the howto on the wiki once you have
gained adequate knowledge and if you still feel the wiki is still
incomplete.
There has been plenty of information given in this thread to
understand how numbers are represented using the file_sink. It's now
up to you to learn from the posts and gain that knowledge for
yourself.
Good luck!
Brian
