Arduino with load cell and matlab grapher help

I am doing a school project and i am using an arduino uno with a load cell (s-type, 200kg capacity) and i need to combine 3 sketches–the load cell sketch, the data logger sketch, and the lcd sketch. i am new to arduino and i am still learning the basics of it like serial communication and that sort of stuff. to make things more difficult i am going to use serial communication to create graphs with a matlab program. i’m decent at programming (new to matlab but good at c++) but i need some help combining those sketches.

Did you have any luck with your project? I am facing a similar situation with the same problem.

Thank you.
