In my code I have a for loop and with every iteration i tell matlab to draw real part of the curve as a solid line and imaginary part of the curve as a dashed line. What I would like to have is for each iteration the real and imaginary part of the same curve to have the same color, could anyone help?

Hi,
a fast and easy solution could be generate a triplette of RGB values randomly at each iteration and you use it as color for both plots, as you can see in the following code:
RGB = rand(3,1);
semilogx(imag(e),'--','Color',RGB)
set(gca,'FontSize',20);
set(gca,'Color','k');
title('Relative Permittivity of Water vs Frequency & Water Temperature', 'Fontsize', 40);
xlabel('Frequency (Hz)','Fontsize', 40) ;
ylabel('Relative Permittivity', 'Fontsize', 40) ;
hold on
semilogx(real(e),'Color',RGB)
I have defined RGB vector that I use as color property for both plots. In this way both plots have the same color.
An alternative you could define a matrix of RGB values in order to control which color you want at each iteration for both plots.
Hope this helps.
