matplotlib gridspec

This example demonstrates the use of `.pyplot.subplot2grid` to generate subplots.  Using `.GridSpec`, as demonstrated in :doc:`/gallery/userdemo/demo_gridspec03` is generally preferred

custom boxstyle

This example demonstrates the implementation of a custom `.BoxStyle`. Custom `.ConnectionStyle`\s and `.ArrowStyle`\s can be similarly defined.

connection style

When creating an annotation using `~.Axes.annotate`, the arrow shape can be controlled via the *connectionstyle* parameter of *arrowprops*. For further details see the description of `.FancyArrowPatch`.

matplotlib connect

ConnectionPatch` can be used to draw a line (possibly with arrow head) between points defined in different coordinate systems and/or axes.
