How to change the appearance of the boxplot with a whiskers?

Hello everyone. I have the following code:

A = [1.128 0.701 0.562 0.469 0.836 0.644 0.510 0.535 0.528 0.585]';
B = [0.630 0.630 1.079 0.635 0.983 0.875 0.747 0.811 0.878 0.943]';
group = [ ones(size(A)); 2 * ones(size(B))];
figure
boxplot([A; B],group)
set(gca,'XTickLabel',{'group A','group B'})

I want to change the appearance of the two boxplots as shown in the figure on the right:

• change dashed line to continuous line
• change the sign of outliers form "+" with a dot or "o"

How is it possible to fix the code?

A = [1.128 0.701 0.562 0.469 0.836 0.644 0.510 0.535 0.528 0.585]';
B = [0.630 0.630 1.079 0.635 0.983 0.875 0.747 0.811 0.878 0.943]';
group = [ ones(size(A)); 2 * ones(size(B))];
figure
boxplot([A; B],group)
set(gca,'XTickLabel',{'group A','group B'})

h=findobj('LineStyle','--'); set(h, 'LineStyle','-');
h=findobj('Marker','+'); set(h, 'Marker','o'); set(h,'MarkerFaceColor','r')

thanks, that's exactly what I wanted!

Can you tell me how to fill each box with different colors? Using the 3 values of RGB.

For that you should probably check some of the other box plotting routines on the File Exchange. This is just one example which seems to offer that kind of control:
