I am trying to find any implementation or how to implement a 100% stacked area chart in MATLAB? Any ideas?

Excel has them: Excel charts

在 MATLAB Online 中打开

doc area

The example from the help:

Y = [1, 5, 3;
  3, 2, 7;
  1, 5, 3;
  2, 6, 1];
area(Y)
grid on
colormap summer
set(gca,'Layer','top')
title 'Stacked Area Plot'

EDIT: I forgot to normalize it...

% Modify Y to get 100% stacked
Y = bsxfun(@rdivide, Y, sum(Y,2));

I am interested in being able to reproduce the area plot (just a fill of 2d data to axis) and staggered behind each other as in the original link to the excel image.

You can use the AREA function:

Y = [1, 5, 3;
     3, 2, 7;
     1, 5, 3;
     2, 6, 1];
area(Y)
grid on
colormap summer
set(gca,'Layer','top')
title 'Stacked Area Plot'

Jesse, I'm not sure this is what you want. This is justed stacked area, not 100% stacked, correct?
