Problems regarding complex Fourier plot of pulse wave

Hi,

I am trying to plot compute and plot the complex Fourier series of a even looking pulse wave with the mid point at the origin. First the pulse width is T/2 and then reduced to T/5. Where T is any arbitrary period. 

Problems:

 I have computed the Fourier series for the pulse wave, however the maximum amplitude does not match the required one. For the pulse width T/2; a 1.5 amplitude is produced which is not 1 as required. How should this be plotted, the Re and Im separately or just the modulus? I only plotted the modulus but the shift is not correct since the lowest value is not even touching the t axis.

Any response would greatly appreciated. I have attached a prime 6 sheet apologies if you don't have prime.
