I want to apply a different color to the bar in yyaxis.
Without yyaxis, the color applies well on the bar graph,
If I try to use yyaxis function, the colors are unified blue.
For example,
figure(2), grid on, hold on
X = [1, 2, 3] ;
Y_1 = [ 1, 2, 3 ; 6, 4, 2 ; 1, 7, 4 ];
Y_2 = [ 10, 12, 21];
yyaxis left
bar(X , Y_1(: ,1 : 3)');
yyaxis right
plot(X , Y_2(:, 1 : 3 ),'-o');
legend('Y_1_1', 'Y_1_2', 'Y_1_3', 'Y_2_1')
Thank you for help!

Hello 승현 이
To add colours to the bars, you just need to use the colororder() function as demonstrated below:
figure(2), grid on, hold on
X = [1, 2, 3] ;
Y_1 = [ 1, 2, 3 ; 6, 4, 2 ; 1, 7, 4 ];
Y_2 = [ 10, 12, 21];
yyaxis left
bar(X , Y_1(: ,1 : 3)');
colororder('default')
yyaxis right
plot(X , Y_2(:, 1 : 3 ),'-o');
legend('Y_1_1', 'Y_1_2', 'Y_1_3', 'Y_2_1')

Ran in:

X = [1, 2, 3] ;
Y_1 = [ 1, 2, 3 ; 6, 4, 2 ; 1, 7, 4 ];
Y_2 = [ 10, 12, 21];
yyaxis left
h = bar(X , Y_1(: ,1 : 3)');
yyaxis right
plot(X , Y_2(:, 1 : 3 ),'-o');
legend('Y_1_1', 'Y_1_2', 'Y_1_3', 'Y_2_1')
color = {'r','g','b'} ;
for i = 1:3
set(h(i),'FaceColor',color{i})
end

Hi,
It is possible to do so by specifying different colour for each bar. This can be accomplished by changing 'FaceColor' for each plotted bar. There are multiple ways to do so, one of which is:
X = [1, 2, 3] ;
Y_1 = [ 1, 2, 3 ; 6, 4, 2 ; 1, 7, 4 ];
Y_2 = [ 10, 12, 21];
yyaxis left
b = bar(X , Y_1(: ,1 : 3)');
b(1).FaceColor = 'blue';
b(2).FaceColor = 'green';
b(3).FaceColor = 'yellow';
yyaxis right
plot(X , Y_2(:, 1 : 3 ),'-o');
legend('Y_1_1', 'Y_1_2', 'Y_1_3', 'Y_2_1')
This might be useful:

one more simple solution without any extra line, just interchange 2 lines
figure(3), grid on, hold on
X = [1, 2, 3] ;
Y_1 = [ 1, 2, 3 ; 6, 4, 2 ; 1, 7, 4 ];
Y_2 = [ 10, 12, 21];
bar(X , Y_1(: ,1 : 3)');
yyaxis left
yyaxis right
plot(X , Y_2(:, 1 : 3 ),'-o');
legend('Y_1_1', 'Y_1_2', 'Y_1_3', 'Y_2_1')
