Subject: [PATCH] In niceScale() when passed yMin and yMax indicate no data,
 cannot simply use w.globals.min and w.globals.max because the user may have
 configured one or both as a function, which can cause those global values to
 be poor substitutes causing undefined behaviour. Substitute sane default
 values in that case.
