plot of differernt regions of specific area in a matrix

I wonder where in the follwing code i can add a condition which i can have the same plot but for regions (connected pixels) which have more than 10 pixels? I really apperciate your help.

Hi Hassan! Try this code:

L = bwlabel(m2 == 2);
lns = 1:max(L(:));
ln = regionprops(L, 'Area');
pm1 = find(ismember(L(:),lns([ln(:).Area]>=10)));
lidx = sortrows([L(pm1) pm1],1);
dplt = mat2cell([(1:size(lidx,1))' m1(lidx(:,2))],...
                arrayfun(@(i1)nnz(lidx(:,1)==i1),unique(lidx(:,1))) ,ones(1,2));
n = size(dplt,1);
k=reshape('ymcrgbwk+o*.xv^>--------',[],3);
dplt2 = [dplt mat2cell([repmat(k,fix(n/8),1);k(1:rem(n,8),:)],ones(n,1),3)]';
plot(dplt2{:})

thanks a lot Anrei.

Another question. I want to make the same plot but for the mean value of each region. I wrote the following code which works. However, I want to show the color of each mean value with the same color was used in the above code for each region.

STATS = regionprops(L,m1,'MeanIntensity','Area','PixelValues');

n_stats = size(STATS,1);

mean_=zeros(n_stats,1);

[m_,n_] = find(cat(1,STATS.Area) >=10);

for i=1:n_stats

mean_(i)=STATS(i,:).MeanIntensity;

end

mean1=mean_(m_);

figure

plot(mean1)
