Hi everyone,

I have to combine plot and area functions in a loop as below. I just want to show the legend for plot and not for area.

My code below show Graph 1:

f = figure;

hold on

for j = tt_n'

h1{j}=plot(Y, D{h}{j},'color',getprop(colors,j), 'linestyle',getprop(linestyle,j),'DisplayName', [num2str(year(Time{h}(j))+s1)]);

h2{j}=area(limx_tot_n{h}{j},limy_tot_n{h}{j},'FaceColor',getprop(colors,j));

end

grid on

legend('show','Location', 'NorthWest');

hold off

How can I delete the legend for the shaded area ?

When I modify the code as the following, I get Graph 2 below:

f = figure;

hold on

for j = tt_n'

h1{j}=plot(Y, D{h}{j},'color',getprop(colors,j), 'linestyle',getprop(linestyle,j));

labels_h1{j}=[num2str(year(Time{h}(j))+s1)];

h2{j}=area(limx_tot_n{h}{j},limy_tot_n{h}{j},'FaceColor',getprop(colors,j));

end

grid on

legend(labels_h1,'Location', 'NorthWest');

hold off

How can I solve this issue ?

Thank you in advance,

在 MATLAB Online 中打开

 f = figure;
 hold on
 for j = tt_n'
     % h1{j}=plot(Y, D{h}{j},'color',getprop(colors,j), 'linestyle',getprop(linestyle,j));
     h1(j)=plot(Y, D{h}{j},'color',getprop(colors,j), 'linestyle',getprop(linestyle,j));
     labels_h1{j}=[num2str(year(Time{h}(j))+s1)];
     h2{j}=area(limx_tot_n{h}{j},limy_tot_n{h}{j},'FaceColor',getprop(colors,j));  
 end
 grid on
 legend(h1, labels_h1,'Location', 'NorthWest');  % only include objects h1 in legend
 hold off
