The general syntax to plot multiple lines within a single plan is: plot (X1,Y1,...,Xn,Yn) Whereas depending on the attributes used in order to customize the display of the lines, the syntax is defined as: plot (X1,Y1,LineSpec1,...,Xn,Yn,LineSpecn) This syntax sets the line style, marker type, and color for each line. legend( arrayfun( @num2str, alpha, 'UniformOutput' , false ) ) I don't understand what you are doing creating the full legend within the loop that is doing the plots though. You may receive emails, depending on your. To use a color like this I have to use 'color' before using the 1:3 color matrix with the plot command.
