How to show the legends of this plot?

How to change the leg1 to show star shape instead of line and how to move the legend to the middle of the figure? Also, the size of first two subplots should be similar to the last one.

Style1 = {'Color',[.8 0.4 0.2], ...
        'LineWidth', 0.5,...
        'MarkerEdgeColor', [.8 0.4 0.2],...
        'MarkerFaceColor', [1 .6 0.2],...
        'MarkerSize',1};

  Style2 = {'kp--', ...
            'LineWidth', 1.5,...
            'MarkerEdgeColor', 'k',...
            'MarkerFaceColor', 'k',...
            'MarkerSize',7};

Record the handles of the objects you are going to produce legend() entries for. Pass those handles to legend() as the first parameter. This will prevent legend from looking for graphics objects and will always use the exact order of the handles that you pass in.

This helped me to understand the legend() a lot more better. Thanks !

• You can change the order of plots to assign the legend as required. So, if you want leg1 to show 1st line then you should plot it before others. For loop can be replaced by:

for nGen=plotthisnGen
   subplot(1,3,sp); 
    hold on
    plot(A, Style2{:});
    parallelcoords(data',Style1{:});
    sp = sp + 1;  
end

• To keep the plots of same size you can define the location of the legend to be inside the plotting area so MATLAB doesn't adjust the size of the subplot :

legend(legend_str{1},legend_str{2}, 'Fontsize',10,'Location', 'North', 'Orientation','horizontal'); 

• This one is little hard to understand but if you want legend to show in the middle of the Figure then you just put legend in the 2nd subplot since it is already in the middle. So, last line should be replaced by:

subplot(132)
legend(legend_str{1},legend_str{2}, 'Fontsize',10,'Location', 'North', 'Orientation','horizontal'); 

I hope it helps!

Thank you for your answer, in this code I need A to be ploted after data.

for nGen=plotthisnGen

subplot(1,3,sp);

hold on

plot(A, Style2{:});

parallelcoords(data',Style1{:});

sp = sp + 1;

end
