Hi, I would like to draw two area graphs in one plot to overlay each other and have transparent colors. but the area plot library in my Matlab 2014b doesn't have faceAlpha properties.
MATLAB: No FaceAlpha property for area plot

Your code works correctly for me in R2016a.
As an alternative, you can use the patch function:
figure(2)a = patch([1:10 10:-1:1], [1:10 zeros(1,10)], 'b');grida.FaceAlpha = 0.2;Note that you have to change your code to define the patch object, here adding a zeros vector to complete it.
Patch wants to draw closed polygons. If you don't want the line from the end of the second patch back to the beginning, then the easiest way is to add a nan like this:
x = linspace(0,10);y1 = 4 + sin(x).*exp(0.1*x);y2 = 4 + cos(x).*exp(0.1*x);patch(x, y2, 'w', 'EdgeColor', 'r', 'EdgeAlpha', 1, 'FaceColor', 'r', 'FaceAlpha', 1)hold onpatch([x nan], [y1 nan], 'w', 'Edgecolor', 'b', 'EdgeAlpha', 0.3, 'FaceColor', 'w', 'FaceAlpha', 0)hold off
