Hi!
I am trying to plot my data with an area plot and I have several subplots for several countries. I just wanted to know how to set a common legend for all subplots describing each color of the plot. Thanks!

What have you done so far?

figure(1)
for i=1:11
subplot(4,3,i)
area(dates,[global(:,i),regional(:,i),local(:,i)],'FaceColor','flat')
a11 = sprintf('%s',country{i});
title(a11);
legend({'World','Regional','Local'},'Location','SouthOutside');
end
But this is giving me a legend for each plot separately.

Some version of this idea could work:
dates = 1:5; % Create Data
G = rand(5, 11); % Create Data
R = rand(5, 11); % Create Data
L = rand(5, 11); % Create Data
country = num2cell('A'+(0:10)); % Create Data
figure(1)
for i=1:12
if i < 12
subplot(4,3,i)
area(dates,[G(:,i),R(:,i),L(:,i)],'FaceColor','flat')
a11 = sprintf('%s',country{i});
title(a11);
elseif i == 12
subplot(4,3,i)
i = 11;
area(dates,[G(:,i),R(:,i),L(:,i)],'FaceColor','flat')
set(gca,'Position',[7.5 1.25 1 1]*0.1)
set(gca, 'Visible','off')
legend({'World','Regional','Local'},'Location','best');
end
end
Run this first. (I am using R2018b.)
Then experiment with your own data to get the result you want.

Thank you for your response!
Here is a little tweaked version I opted for instead which is giving me the result I wanted with a row legend underneath the figure. Any suggestions on optimizing this line would still be appreciated.
clear all;
dates = 1:5; % Create Data
G = rand(5, 11); % Create Data
R = rand(5, 11); % Create Data
L = rand(5, 11); % Create Data
country = num2cell('A'+(0:10)); % Create Data
figure(1)
for i=1:11
subplot(4,4,i)
area(dates,[G(:,i),R(:,i),L(:,i)],'FaceColor','flat')
a11 = sprintf('%s',country{i});
title(a11);
end
legend=columnlegend(3,{'World','Regional','Country-specific'});
set(legend,'Position',[1.1 1.3 7 1]*0.1);

My pleasure.
I cannot run that because the ‘columnlegend’ variable does not exist in the code you posted. Also, ‘columnlegend’ is not a MATLAB function.
