How can I create a plot with subplots in a loop?

Question

Hi everyone,

I am trying to create a plot with subplots within a loop. The code so far is:

x = randn(100,13);
D = 1966
dis = 3
[T N] = size(x);
for i = 1 : N
VARNAMES{i} = i;
end
time = datetime(D,1:T,1);
figure;
for k = 1:N
    subplot (ceil(N/dis),dis,k)
    filename = plot( time' , x(:, k ) );
    xlim(datenum([min(time) max(time)]))
    title ( VARNAMES(k));
    hold on
end

But I get an Error message ''Error using xlim (line 31)

Limits must be a 2-element vector of increasing datetime values.''

Could you please point out where is the mistake?

The issue seems to be with xlim(), rather than with creating subplots within a loop.

If you remove the below line, subplots are created within a loop.

xlim(datenum([min(time) max(time)]))

However, you can use the xlim command in this code by removing the datenum function:

x = randn(100,13);
D = 1966
dis = 3
[T N] = size(x);
for i = 1 : N
VARNAMES{i} = i;
end
time = datetime(D,1:T,1);
figure;
for k = 1:N
    subplot (ceil(N/dis),dis,k)
    filename = plot( time' , x(:, k ) );
    xlim([min(time) max(time)])
    title ( VARNAMES(k));
    hold on
end
