[HELP] XY Plot from Matrix

Unfortunately I can only read files in 3.0 format but not in 3.1 - PTC has decides that even every subversion should have its own file format and being incompatibel with older versions . crazy.

So unless you provide a screenshot or a pdf printout of your file, I am unable to see what you are trying to do.

Usually it should work without problems to plot one vector over another one, given they have the same dimension and given that they really are vectors.

If you feed your function with a range variable, neither that variable nor the function output are vectors. Maybe thats the problem.

If thats the case, try to turn Re into a vector and create Cf by feeding that vector into your function - possibly you have to vectorize that function call.

Cf is a vector, but Re is a range variable.   You need to make Re into a vector, so just type '=' after the expression.  This makes Prime iterate over the range variable and return a vector.
