It did when I tried it. First, make sure you haven't created your own
area.m function or variable that's shadowing the built-in function:

which -all area

Next, call AREA with an output argument (to store the handle to the
areaseries object AREA created) and GET the properties of that handle. Make
sure the FaceColor property of that object is cyan [0 1 1].

Looks like MATLAB thinks it is filling in the right color but it isn't being displayed as so. I've tried other colors too in the FaceColor property and it still results in a filled in dark blue color as seen in my link below. I may just have to live with this if there is no other choice.

What is your renderer set to?

What is a rendered set? (?) Thanks.

this reflects a false setup of your X/Y parameters for PATCH...
can you show CSSM how you called the function(?)...
note: PATCH is much more versatile compared to AREA, which comes with a simple level arg to close your patch...
