If you can do what you need with the raw data, why worry about
the aggregated data?

I assume you are using the packages Histograms` and
StatisticalPlots` to create the plots with the raw data. And as
you seem to have found out, both are designed to work with what
you are calling the raw data.

=46or the aggregated data perhaps something like the following
will work for a histogram

data = Transpose@{Range[0, 1, .1], RandomInteger[10, {11}]};
ListPlot[data, Filling -> Axis]

=46or a BoxWhiskerPlot, you will need to write your own routine to
handle the aggregated data.
