Usually, Mathematica returns a syntacticly correct expression unevaluated when it does not know what to do with it. Plot will return some pair of axes. For instance, if one evaluate the following expressions, f[x] is a function without any definition and Plot just draws a pair of axes. ClearAll[f] (* To be sure that f will not be defined. *) Plot[f[x], {x, 0, 10}] -- Jean-Marc
