How do I plot rectangles with filled color on a 2D plot?

Hi all,

Seeking helps from esteemed Matlab users/experts.

I need help on how to plot rectangles with filled color on a cartesian coordinate (2D) plot. Please see attached figure below the expected plot I am looking forward to.

Regards,

Taufiq

Hi all, I think I have found the answer by further googling/refining the question.

In case others have similar question, below is the syntax from the Matlab's documentation itself.

You might want to have a look at the fill command as well - a bit more versatile

Thank you @David Fletcher 😊 for recommending an alternative to rectangle method, which looks me to a little bit more simple and more flexible as you said

Read about fill, patch. You need to have coordinates of the vertices.

Example:

% Vertices of rectangle 
P = [0 0 ;0 1; 1 1; 1 0] ;
patch(P(:,1),P(:,2),'r','EdgeColor','k')

Thank you @KSSV for recommending an alternative method to rectangle i.e. patch. As suggested by @David Fletcher earlier, now I know at least these are 3 methods I could use to accomplish my objective:

• rectangle
• fill
• patch

Truly appreciate it guys 😊
