Histograms next to one another with same x and y scale
KDB
I am creating several histograms for several size classes. Is there an
easy way to plot histograms next to one another with ggplot2 on the
same graph with the same continuous x and y scale. It should look
something like the lower part of this graph without the quantile
regression fitting:

Probably the easiest way is to facet on time. If needed I'll be happy
to give a more detailed explanation if you provide a reproducible
example.

My data would look something like this
sizeclass = c(rep(1,times = 15),rep(3, times = 25), rep(7, times =
20))
parameter = c(rnorm(15, mean = 5), rnorm(25, mean = 15),rnorm(20, mean
= 35))
sizeclass <- data.frame(sizeclass,parameter)
I would like to have histograms of the parameter (rotated as in the
example in the link i gave before) ordered along the x-axis according
to their size classes. The histograms should have a common y-axis and
the spacing of the histograms should be in proportion to the
proportions between their respective sizeclasses. I hope this is
understandable. Can this be done with ggplot2 ???

So, i guess there is really no way to do this, i just figured if
something like this can be done for boxplots, it should also be
possible for histograms...

complication is that the y-axis isn't mapped to one variable - but is
a linear combination of time and count. I think this sort of plot
very often makes sense, but it's not entirely clear to me how it
should fit into the grammar.

This parameter is currently fixed in ggplot2 - mainly because I think
it easily confuses readers who probably expect a standard boxplot.
