hi, i am ploting the argument of the complex number z:=a+b*I but i dont understand why i get two diferent plots for argument(z) and arctan(b/a)

 

it should be the same i guess, but there is a slight diference in the plots, i know the arctan(b/a) is the correct but i dont understand why argument(z) is not.

 

thanks
