Hi, my code below takes values for different muscles in different condition. Does anyone know how I can change my plot line colours and styles so when my figure is created it is easy to tell which line is for which muscle in each condition.

I have 8 muscles and 3 conditions.

Maybe the colours for each muscle would be different and the the line style for each condition will be different (i.e, line, dashed and stars) ?

Also does anyone know how I can automate the legend?

I have attached a picture of my current graph

for i=1:length(mod_dirs) 
    %% ----------------------------------------------------MA data
    % read the MomentArm (MA) data
    filename = [ base_dir mod_dirs{i} '\MA_MTL\' 'right_hip_muscle_flexion_MA.sto'];
    variables = { 'time','add_mag1_r','add_mag2_r','gem_r','glut_med1_r','glut_min1_r','glut_min2_r','grac_r','quad_fem_r' };
    [ data, var_names, info ] = read_select_opensim_data(filename, variables);
    time             = data.matrix(:,1);
    ma_flexion   = data.matrix(:,2:8);
    ma_flexion_cm=ma_flexion*100;
    [cycle_time,TN_ma_flexion]=normalise_data_points(time,ma_flexion_cm,t_cycle_start,t_cycle_end);
   
    % create a plot of the MA of a selected muscle around the flex/ext axis
    h1=figure(100);hold on;
    plot(cycle_time, TN_ma_flexion);
    xlabel('Time [%gait cycle]');
    ylabel('Muscle moment arms [cm]');
    title({'Adductor moment arms',' during walking'});
    legend( ); 
    %'sw_+0.00' , 'sw_+0.01', 'sw_+0.06'
    set(h1,'Position',[10 10 500 500])
