MATLAB legend iteration - ntuzxy/blog GitHub Wiki
Welcome to the blog wiki!
To plot figures using for
loop and generate legend spontaneously.
%% plot
x=1:9;
str = strings(1,15);
str_num = 1;
figure;
for i= 1:2
for j = 3:4
y = x.*(i*j);
hold on
plot(1:9, y,'-o');
str(str_num) = strcat('i=', num2str(i), ',j=', num2str(j));
str_num = str_num + 1;
end
end
legend(str)
You can also plot separately and save in .fig format.
%% plot and save
x=1:9;
str = strings(1,15);
str_num = 1;
figure;
for i= 1:2
for j = 3:4
y = x.*(i*j);
% hold on
plot(1:9, y,'-o');
str(str_num) = strcat('i=', num2str(i), ',j=', num2str(j));
savefig(strcat(str(str_num),'.fig'))
str_num = str_num + 1;
end
end
legend(str)
