I have a cell array and want to plot each of the cells on a tiled layout.

I have a cell array which contains nx2 matricies in each cell. I'm trying to figure out how to plot each of those cells (x vs y) in a loop. Any ideas?
This is what I have:
numColmns = size(Data, 2);
for i = 1:2:numCols-1
A{i} = Data(:, i:i+1);
end
B = A(:, 1:2:end); %removes empty cells in cell array A
numPlots = length(B); %number of plots to make
tiledlayout(numPlots,1) %total number of plots in a row by 1 column
%insert loop where it automatically plots all cells in B
B gives me B{1}, B{2}, ... , B{n}, etc.

So "A" is your cell array, but what is Data? Give an example of Data, either in a .mat file or with code to generate it.
And what is tiledlayout()? Is that a function you're supposed to build that uses plot()? How many plots do you want? Each curve in a separate plot (using the subplot() function), or all curves on the same plot?

Hi Khiana,
You can use the below code
A_new ={}; % Cell array declared as A in your code
numColmns = size(A, 2);
for i = 1:2:numColmns-1
A_new{i} = A(:, i:i+1);
end
B = A_new(:, 1:2:end); %removes empty cells in cell array A
numPlots = length(B); %number of plots to make
tiledlayout(numPlots,1) %total number of plots in a row by 1 column
for i = 1: numPlots
a = B{i}';
nexttile
plot(a(1,:),a(2,:))
end
