I want to know how to display one or two working space gamuts in any of four different color spaces such as lab\xyY. The working space include CIE RGB/sRGB.etc. It was like the picture in below.

I have a gamut display app (attached) I wrote but it's pretty primitive. I've been asking for something like this for a long time. I know a developer on the Image Processing team wrote a much better one but it's not released yet as part of the toolbox. You can call the Mathworks and ask for it and they might give it to you.

Yes, you can use rgb2xyz() or rgb2lab() and get new images in those color spaces. Then you can use the same code with those images to make a 3D scatterplot.
