decreasing gap between horizontal boxplots

Dear All,

I have 5 boxplots that are aligned horizontally using 'orientation' argument. So, y axis includes the names of each boxplot.

I am trying to decrease the gap between horizontal boxplots. I failed to do so. Any help or suggestion is so much appreciated.

I tried decreasing the width of the boxplots using 'widths', I also tried using the 'positions' argument. I realized that they act reversely, meaning that when I decrease the 'widths' the gap between the plots increase. I also used 'positions' argument, by first specifying a vector named X5. CE50 is a matrix which has 5 coloumns of data, so that is why I have 5 boxplots.

X5=[0 0.2 0.4 0.6 0.8]

figure

boxplot(CE50,'Notch','on','Labels',{'box1','box2','box3','box4','box5'},'orientation','horizontal','Colors','k','OutlierSize',2,'Symbol' , 'o', 'positions', X5)

PS. I donot want the type called 'compact', just donot like its appearance. So, I want to do what I want keeping the type as 'traditional'.
