How to change only 1 bar in a graphic bar that is grouped

Y1=[CO_P2_30, NOx_P2_30, UHC_P2_30

CO_P3_10, NOx_P2_10, UHC_P3_10

CO_P3_5, NOx_P2_5, UHC_P1_5

CO_P2_3, NOx_P1_3, UHC_P1_3];

b1=bar(X,Y1,'grouped');

b1(1).FaceColor='#000000'; % CO-P1

b1(2).FaceColor='#828282'; % NOx-P1

b1(3).FaceColor='#D5D5D5'; % UHC-P1

X = categorical({'30','10','5','3'});

X = reordercats(X,{'30','10','5','3'});

I want to change the color of the first bar of the bar group of 30. When I try to change it the program change de color of the first bar of all the groups.

Hi!

Try something like this:

y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
barH = bar(y) ;
barH(1).FaceColor = "flat" ;
barH(1).CData(1,:) = [0 1 0] ; % set the first bar color to green
