Which data are stored in handles of boxplot?

I created a boxplot with

H=boxplot(x);

Could someone which data are contained in H? I think they are not the statistical values (e.g. median).

They're the handles of the line objects it created. They've been cast to double (because it's rather old code), but if you're using R2014b or newer, you can get to the objects like this:

load carsmall
h = boxplot(MPG, Origin);
h = handle(h)

h = 

7x6 Line array:

    Line    Line    Line    Line    Line    Line
    Line    Line    Line    Line    Line    Line
    Line    Line    Line    Line    Line    Line
    Line    Line    Line    Line    Line    Line
    Line    Line    Line    Line    Line    Line
    Line    Line    Line    Line    Line    Line
    Line    Line    Line    Line    Line    Line

Then you can set properties on them, such as color and line width.
