75Through Library

  • TikZ Library through

  • \usetikzlibrary{through} % and plain
    \usetikzlibrary[through] % Cont

    This library defines keys for creating shapes that go through given points.

  • /tikz/circle through=coordinate(no default)

  • When this key is given as an option to a node, the following happens:

    • 1. The inner sep and the outer sep are set to zero.

    • 2. The shape is set to circle.

    • 3. The minimum size is set such that the circle around the center of the node (which is specified using at), goes through coordinate.

    \usetikzlibrary {through}
    \draw[help lines] (0,0) grid (3,2);
    \node (a) at (2,1.5) {$a$};
    \node [draw] at (1,1) [circle through={(a)}] {$c$};
