plot filled rectangle and appear on legend

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?

[Walter Roberson]

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() )
