Do you mean "graph" in:
  • the mathematical sense, or
  • a colloquial "picture" sense?
If it is the former, the presumably some metrics of an image could be represented in a graph, but this depends on exactly what metrics you want to visualize.
If it is the latter, then the very first result I got searching a major search-engine for the term "matlab image" was for this page:
http://www.mathworks.com/help/matlab/ref/image.html
Perhaps those examples might be of interest to you.

I too, have no idea what this means. Christina, please clarify. Presumably you already know about imread() and multibandread().

Hi Christina,
Do you know that you can simply view the image in MATLAB by using
imshow('c:\mypicture.jpg')
If processing required on the image, you can read the image into MATLAB, perform the process and then view you as above
myPicData = imread('c:\mypicture.jpg')
%%process
imshow(myPicData)
Let us know what exactly you want to do, so that we can help better.
