Hello everyone, I plot this bar plot in order to show the difference between each model (3 models) in condition A and condition B. x = rand(3,2);
x = rand(3,2);
h = bar (x);
I want to set, for example, red for the first model in condition A and blue for condition B (In this model).
As well as two different colors like green and yellow for the second model in each condition. Like this plot below:
And also, set the corresponding legend for each color. So I want to have 6 items in legend (different colors).
Any suggestion is really helpful
Thank you.

For the first part of your question, you can do so as follows:
x = rand(3,2);
h = bar (x);
h(1).FaceColor = 'red'
h(2).FaceColor = 'blue'
For the second part, patterned face colours aren't provided for with the bar() function. When you plot a bar chart such as:
h = bar(rand(3,6))
you can continue to modify the colors of any model using the same procedure as above. Additionally the legend will update for you accordingly:
legend('model A','model B','model C','model D','model E','model F')

You can modify the individual bars then as follows:
b(3).FaceColor = 'g';
b(4).FaceColor = 'm';
b(5).FaceColor = 'k';
b(6).FaceColor = 'y';

2nd Part of Question (Pattern Face)
This code is computation intesive and is just for display purpose. (considering that max value is less than 1)
figure,
x = rand(3,2);
c = [1 2 3];
h = bar (c,x,'BarWidth',1);
h(2).FaceColor = 'none';
h(2).LineWidth = 2;
%
jj = 1;
hold on
%
a =gca; clr_array = a.ColorOrder;
for mm = 1:3
for i = x(mm,2):-.01:0
if(jj == 1)
jj = 2;
bar(mm,[0;i],'FaceColor','w','EdgeColor','none','BarWidth',1)
else
bar(mm,[0;i],'FaceColor',clr_array(mm,:),'EdgeColor','none','BarWidth',1)
jj = 1;
end
end
bar(mm,[x(mm,1);0],'FaceColor',clr_array(mm,:),'LineWidth',2,'BarWidth',1)
bar(mm,[0;x(mm,2)],'FaceColor','none','LineWidth',2,'BarWidth',1)
end
