end
what I would like to do is a boxplot having Year on the x-axis and Trials on the y axis. For each year, I would like to produce a box plot over recalled dummy.
Please, notice that I am trying to do it all in one plot and not something like:
Code:
bys Year:
. Is it possible to achieve it?

Thank you all,

Federico
