Hi,

I want to plot a boxplot with multiple datasets(4 years in my case). I did something like this.

data=[a;b;c;d];

group = [repmat({'2011'}, length(a), 1); repmat({'2012'}, length(b), 1); ... repmat({'2013'}, length(c), 1); repmat({'2014'}, length(d), 1)]

boxplot(data, group,... 'symbol','','factordirection','auto')

How do I make the whiskers 5th and 95th ?

You could use the "whisker" parameter in the "boxplot" function. i.e

boxplot(data, group,... 'symbol','','factordirection','auto', 'whisker', multiplier)

According to the following answers post ( here ), the multiplier for 95 percentile is 0.7193. Check the linked answers post has some more details.

Do I have mention separately for 5th percentile ? Also when I calculate separately the percentiles for each dataset, they do not match with that on the figure ? What is the best way to plot a boxplot with multiple datasets and with whiskers being 5th and 95th percentile ?
