Hello,

If I'm understanding it well, this is a time series problem, use time series
functions.

You can use 'stats::ts' or, what seems to be better for your problem,
package zoo.
Here is an example.

library(zoo)

flow <- read.delim( ... etc ...


flow$Date <- as.Date(flow$Date, format="%m/%d/%Y")
head(flow$Date)  # see if it worked

zflow <- zoo(flow[,-1], order.by=flow$Date)  # make the time series

plot(zflow)                      # all 8 series, ugly axes
plot(zflow$USGS700)  # just the first series, ugly axes

If this helps, then make it pretty with Jim's ideas.
See also the 'plot.zoo' help page, it has several examples with fancy
labels.
