Hi,
I'd like to have something like that
I know that I can use rectangle function, but then it is not appearing on a legend.
Any suggestions how to solve the issue?

Use fill() such as
fill([xmin xmax xmax xmin], [ymin ymin ymax ymax], 'facecolor', 'y')

If I'm using the fill multiple times, how do I create a legend so that the it will appear only once?
Maybe I shall use the fill in different way?

Record the handle of one of the fill() calls. Pass only that handle to legend() (along with the handles of any other objects you do wish to legend() )
