Your "x" is 2-D; what you want is rand(10); or you can do scatter(x.ravel(), x.ravel()). Your example does point to a bug in scatter, however; it should not be failing with an obscure error message like that. (In mpl from svn trunk it still fails, but with a different obscure error message.) I don't know any good reason why it should not be able to handle the 2-D inputs. I will take a look.
