Details:

Hey! If I plot complex numbers in polar plot, the rho and theta values seems
to be flipped, so that the result plotted is wrong.

So insted the first value is the abs, and the complex number the argument
(arg), it is completeley the way round.
If I plot it via value (abs) and argument (rad) instead the complex numbers,
the result is correct.

For example:
polar(1+i,"+") should give me an abs of sqrt(2) and an angle of 45 degree.
Instead it is somewhere else, short before 60° at a value of 1. If i type
in:
polar(pi/4+sqrt(2)*i,"+")

the result is plotted correct. So for me a clear simple flip, that the complex
number isn't correctly interpreted.
