Avi/Jeff/Burt,

Here are the head and tail of one data file:

(Water years begin October 1st and end September 30th.)

The other three locations have the same format.

The boxplots for each PLACE (site_nbr) should summarize all MEASURE (cfs)
values for all recorded data (DATE).

The R tibbles have a datetime column which could be the DATE.

If I assemble all 4 sites into a single tupple I suppose it would have three
columns PLACE (the grouping factor), DATE (on the x axis), and MEASURE (cfs on
the y axis) and each boxplot would be grouped so the
command would be:

disc_plot <- ggplot(df, aes(x = group, y = cfs)) +
 	geom_boxplot()

Is this close?

Thanks,

Rich
