Sure, the mathematica command

ComplexPlot[Im[Zeta[s]], {s, -10 - 10 I, 10 + 10 I}, 
 PlotLegends -> Automatic]

Does it and produces the plot below (notice that the color corresponds to the argument, so red is positive, and blue(?) is negative. I am not sure how much of the complex plane you want, but this is in the square with vertices at $-10 - 10 i$ and $10+10 i.$
