Hi Mike,
thanks for your interest in pgfplots! I am glad it proves to be useful.
Concerning your request to typeset ticks without math mode: you almost
had it except that \pgfmathprintnumber beats you a bit. You are right;
it really starts math mode implicitly.
There are two potential cures: the first is to write
\pgfmathprintnumber[assume math mode,verbatim]{\tick}%
and the second is to use \pgfmathprintnumberto instead of
\pgfmathprintnumber, i.e. something like
yticklabel={
\pgfmathprintnumberto[verbatim]{\tick}\TEMP
%
\TEMP =
%
\romannumeral \TEMP%
},
In the first solution, the 'assume math mode' key tells pgfmath that it
should not ensure math mode on its own; it silently assumes that you
know what you are doing.
The second solution does not typeout the numbers: it stores the result
into the argument which comes after the number (in our case, it is
\TEMP). We can use this value in many ways; the simplest is to typeset
it (by writing \TEMP). A more complicated way is to prefix it by
\romannumeral (which is a bit strange, I admit it ;-) ).
This should allow your use-case.
Kind regards
Christian
