Digital Filter Design Graphics

Hello.

I am using MATLAB 2010B / win7 and have the filter and signal proc toolbox.

I have some filtering code up and running and it works fine. I would like to include a schematic/ graphic of the design in my work. I have heard there is a function in MATLAB that will design filter layout graphics for you, but I cant seem to find it.

Can anyone tell me what the function/package is called? Thank you
