Go back and read the instructions for posting, please.  You described a figure, but you DID NOT ask a question.  You DID NOT explain what it is that you don't understand.  You DID NOT show any of the work you have done so far or what you have tried. If you want help with this, repost it following the instruction.  Do not e-mail a response as that will likely be ignored.
