MATLAB: Imshow() for multiple selected objects

Question

Hi,

I have an image with ~200-250 labeled objects. How can I use imshow() to display multiple selected objects?

When I try this:

imshow(LL == 200)

It works to show the object labeled 200. Say I want to see 200 and 201. I tried:

imshow(LL == 200)
hold on
imshow(LL == 201)

This erases 200 and shows just 201.

Thanks for your suggestions and tips!

image(): https://www.mathworks.com/help/matlab/ref/image.html is better suited for this case. Or even pcolor(): https://www.mathworks.com/help/matlab/ref/pcolor.html.
