How to have a common label for all x and y axes in case of subplots?

问题

I have used the following loop to get subplots:

for j=1:19;
    Aj=B(j,:);
    subplot(5,4,j);
    plot(Aj,h)
end

For all these subplots, I need to have only one x-label and one y-label. How to do this? Also how to insert legend to all the subplots?

回答1:

You can use suplabel from the FileExchange to have combined x and y label for all subplots.

Example:

subplot(1,2,1);
plot(randperm(40)); hold on; plot(randperm(40));  %Plotting some random data
legend('show')   %To show the legend

subplot(1,2,2);
plot(randperm(40)); hold on; plot(randperm(40));  %Plotting some random data
legend('show')   %To show the legend

%Using suplabel from the FileExchange to give a single x and y label for all subplots
suplabel('Combined X label','x');
suplabel('Combined Y label','y');

Output:

---

^{Sometimes you have to maximize the figure window to see the xlabel when using suplabel.}
