Please first enter your formulae onto a Mathcad worksheet and attach that worksheet to your posting.

 

Success!

    You can define the frequency range taking as minimum frequency the smallest value among the absolute values of the poles and zeros and as maximum value of the frequency range, the maximum value among the absolute values of the poles and zeros. The step amplitude can be defined dividing the difference of the previous values by the number of steps. I have considered as a minimum value of the frequency Fz divided by a thousand and as a maximum value, Fp multiplied by one hundred. To have a larger diagram you can replace a thousand with ten thousand and one hundred with a thousand or ten thousand or even more, that is, they are chosen according to your needs.
