matlab输出箱线图的五个特征值,绘制分组箱线图Matlab的最有效方法

I have 3 vectors: Y=rand(1000,1), X=Y-rand(1000,1) and ACTid=randi(6,1000,1).

I'd like to create boxplots by groups of Y and X corresponding to their group value 1:6 (from ACTid).

This is rather ad-hoc and looks nasty

for ii=

dummyY(ii)={Y(ACTid==ii)};

dummyX(ii)={X(ACTid==ii)}

end

Now I have the data in a cell but can't work out how to group it in a boxplot. Any thoughts?

I've found aboxplot function that looks like this but I don't want that, I'd like the builtin boxplot function because i'm converting it to matlab2tikz and this one doesn't do it well.

EDIT

Thanks to Oleg: we now have a grouped boxplot... but the labels are all skew-whiff.

xylabel = repmat({'Bleh','Blah'},1000,1); % need a legend instead, but doesn't appear possible
