Short Answer: No. It displays within the Tk window space
Long answer: I assume you are referring that question to me and the Superformula link I left above.
If that is the case, the issue with the separate window comes what Gnuplot driver you are using. Read the docs or google for "Gnuplot drivers". You may a default setting in the Gnuplot resource file, to pop a separate window.
