Is it possible to easily modify a
Manipulate such that the slider automagically skips certain values?
For example, say I am plotting an equation that's perfectly well behaved for all values of
x=1 except for
x=0.25 where it blows up and causes Mathematica to emit many error messages. I could, of course, check for
x=0.25 in the body of the
Manipulate and then do something sensible but it would be nice if I could just say to
Manipulate 'Avoid x=0.25.'
