Matlab - Extract values from boxplot（从箱图中获取数据）

How to extract values from built in boxplot function?

BOXPLOT returns the array of handles for different graphic objects.

At default parameters (plotstyle set to outline, etc) the output is 7 x M array of handles, where M is number of boxplot groups, each having the following 7 handles:

1. Upper Whisker
2. lower Whisker
3. Upper Adjacent value
4. Lower Adjacent value
5. Box
6. Median
7. Outliers

At different parameters boxplot may return different number of handles, so it's better to find what you need by tag.

To extract the data you have to access the Data property of particular object, if this property exists.

h = findobj(gcf,'tag','Outliers');

xdata = get(h,'XData');
ydata = get(h,'YData');
