1) Suppose you've been mucking around, changing defaults for various
commands (e.g., ListPlot), and don't remember what the default options
were. Is there a way to set all the options for a given command back to
their default (startup) values?
(Other than shutting down and restarting.)
2) I still find the whole PrivateFontOptions and "OperatorSubstitution"
-> False options for use in graphics output confusing (and poorly
documented).
Suppose I want all the Ticks, Axes, Frame and Plot Labels, Text created
in Prologs and Epilogs, and generally any alphameric type appearing
anywhere in any graphics created by Plot, ListPlot, ParametricPlot,
DisplayTogether, etc, all to be Helvetica Font Family, FontSize 12,
FontWeight Bold, and no Operator Substitution, globally in a given
notebook.
What incantations of FormatType -> OutputForm or PrivateFontOptions or
"OperatorSubstitution" -> False do I put in the initialization section
of the notebook, in what form?
3) Trial and error seems to show that in the generation of a graphic,
graphic elements (lines, points, etc) are laid down in the order in
which they're invoked, e.g., Lines or Text in a Prolog are overwritten
by subsequent curves or points, whereas stuff in an Epilog overwrites
already generated graphic elements. (I assume layers are at work here.)
The axes and tick labels, however, always seem to be laid down first, so
that everything else overwrites them, which is opposite to how I'd like
to do it. (If a blue curve passes through a black tick label, seems
more sensible to have the tick label on top.) Is there a way to write
the axes, or at least the tick labels, last?
