# Errors when plotting zeta function parametrically

I have the following piece of code:

```
def f(x):
return(real_part(zeta(1+x*I)).n())
def g(x):
return(imag_part(zeta(1+x*I)).n())
parametric_plot([f(x),g(x)], (x,2,10))
```

It should be moderately clear what I'm trying to do - I want to produce a plot of Riemann zeta function on the line Re(z)=1 using parametric plotting. However, when I try to plot this, I get an error `TypeError: cannot evaluate symbolic expression numerically`

. I also tried the same thing without the `.n()`

, but then I get an error `TypeError: unable to coerce to a real number`

. I couldn't find any help online.

It's worth noting that trying to plot function f(x) I get the same error with `.n()`

, but it works just fine without it (as opposed to parametric plot). Does anyone have an idea how to fix the issue?

Thanks in advance.
