parts chart

[Dan J. <ji...@ji...>]

Maybe as quick way to find how to adjust different parts of a graph,
there should be distributed in the docs some .png files with arrows
pointing to each part of a graph, with names of that part.

E.g. it took me an hour to find out the name of the part that was
bothering me was "key", I needed to unset "key", and not "title",
"label" etc.

Splotting a sphere looks squashed.  I don't know how you can convey
whatever one needs to do to unsquash it on the diagram I call for
above, unless it is axis related...
