Are you sure, you're using the most recent version of plot_options (i.e. have 
you done svn up, lately)? I have recently added another trick to make sure 
that in this case (xvar) missing, the code is not considered to be "valid" as 
long as only one of min/max is entered. Therefore, this code should never 
actually be run (the submit button is disabled, and the preview is not 
updated), and it doesn't here.

You are right though, in that it still should not generate any "min (...)" in 
this case, even if it's just temporary. I'll take care of that.
