the topic as how to define and use user defined functions / macros / procedure
could have some more explanation / samples.

also a suggested way as how to handle and use the definition of
multiple (different) graphics within a single file could be helpful.
e.g. where to put the graphics definitions. how to re-use pieces of
graphics for other images (like axis frames).
