How to plot a bar on a bar in a bar graph

Hi,

I would like to plot a bar graph, and then have a percentage of each bar "shaded out" or change color to indicated what percentage of this data passed a check.

The link below is a picture depicting what I would like to plot:

Realize this can be done more easily using optional inputs to the bar function.

x=1:2;
y=[10 12];
new_y=[3,5];
bar(x,[y',new_y'],'stack')

x=1:2;
y=[10 12];
perc=[25 50];
new_y=[y.*perc/100];
bar(x,y,'b'),
hold on, 
bar(x,new_y,'b')
alpha(0.2)
hold off
