I have 10 arrays of data. Each array creates 10 lines (data: 181X10) on a plot in the same color using plot(freq(:,i),data(:,:,i),ss{i}, 'LineWidth', 3). This give me 10 groups of 10 lines on the plot with each group color specified by SS. SS is a cell array that specifies the color used for each set of 10 lines: ss = {'b', 'g', 'r', 'c', 'm', 'y', 'k', 'b--', 'g--', 'r--', 'c--', 'm--', 'y--', 'k--', 'b*--', 'g*--', 'r*--', 'c*--', 'm*--', 'y*--', 'k*--'}. this all is contained in a FOR loop from 1:10. Labels are contained in a cell array: mb = {'data1' 'data2' .....}.

For example the first array of data plots 10 lines all in blue, the second array plots 10 lines all in green and so on up to 10 arrays (last array is 'g--'). My issue is how do you get the legend to display the correct label and cooresponding color for each group of 10 lines for the 10 arrays so the plot, legend color and style match ?
