Changing color in grouped barplot in Matlab

Question

This is my matrix

n =

   46.4000   51.8000
   44.8000   44.9000
   67.2000   85.0000
   54.4000   60.3000
   43.2000   57.0000
   51.2000   68.0000
   75.2000   76.0000
   44.8000   51.3000
   67.2000   72.2000
   70.4000   71.2000

If I plot it like bar(n, 'grouped') it shows

I want to change the default colors instead of blue red I want green and yellow

I tried like this way bar(n, 'grouped','g','y') But it is showing

can any one help me ?

You can use the 'FaceColor' property of the handles to the objects:

n=[46.4000   51.8000
   44.8000   44.9000
   67.2000   85.0000
   54.4000   60.3000
   43.2000   57.0000
   51.2000   68.0000
   75.2000   76.0000
   44.8000   51.3000
   67.2000   72.2000
   70.4000   71.2000];
bar_handle = bar(n,'grouped');
set(bar_handle(1),'FaceColor',[0,1,0])
set(bar_handle(2),'FaceColor',[1,1,0])

The documentation explains how to set the colors here.
