# The same as above, with manual filtering
# Note that you have to specify the factors and you have to set the xtics as well.
# However, you have greater control over the appearance of the plot
# e.g. the order of the boxplots, their colors, the tic labels
# The previous form is intended for interactive usage while the latter form is better suited
# to creating publication-ready graphs.
# Note: we turn off autoscaling for the last two categories so that outliers do not
# expand the range on y even though they are not shown.
