For loop for multiple figures

I have just started learning image proccesing and I was following the tutorial on math works which has the following link : https://www.mathworks.com/help/images/image-enhancement-and-analysis.html I wanted to change the following part:

    grain = false(size(bw));
grain(cc.PixelIdxList{50}) = true;
imshow(grain);

with following code to obtain all grains in corresponding figure so I used the following code:

for a=1:95
  grain(cc.PixelIdxList{a}) = true;
figure; imshow(grain);
end

However, each time for loop plots over the previous figure. What did I do wrong?

Move the figure command and imshow outside the loop:

for a=1:95
  grain(cc.PixelIdxList{a}) = true;
end
figure;
imshow(grain);
