I'm trying to copy the behaviour of this question: Using tikzlibrary spy without magnifying line width and/or mark size. I would like to change the shape of the spy to rectangle, but I'm failing at the scope (which I have to admin that I don't really understand why works in the original question). Could someone help me out?

The MWE:

You almost had it, you just need to define the \clip rectangle in terms of the spyviewer node:

\clip (spyviewer.south west) rectangle (spyviewer.north east);

  • Ah, awesomeness. Couldn't figure that one out...

  • This code doesn't have the same output as in your picture. The spy box is completely blank.

  • @joaocandre: Works for me (TikZ 2.1, pdflatex). What version of TikZ are you using, and which compiler?

  • Also TikZ 2.1, doesn't work with either latexmk and pdflatex. What exactly would I have to change in your code to just amplify 1000x the last, say, 20 values of the plot? I don't really mind having the spyfactor hardcoded into the file.
