How do I make a boxplot with a few groups?

a = rand(10,2);
b = rand(10,2);
boxplot([a,b]);

I want to have one figure with to groups - a and b, where the two vectors of 'a' will be close and the two vectors of 'b' will be close, but the two groups will be far from one another.

Thanks,

Ziv

In addition to Abdolkarim Mohammadi-Balani's perfectly fine answer,

• Use a grouping variable along with the "Group Appearance" options described in Matlab's boxplot() documentation.
• Checkout boxplot2 from the file exchange
• Check out boxplotGroup from the file exhchange.

You can add some columns of NaN.

a = rand(10,2);
b = rand(10,2);

c = nan(10,2);

boxplot([a,c,b]);

xticks ([1,2,5,6]);
xticklabels (["a1","a2","b1","b2"]);
