plots 1 of the 15 graphs of streamflow statistics on a single page

Description

Part of the flowHistory system. It is designed to create each of the component graphs for the function plot15. The 15 graphs include annual and four seasonal graphs for each of 3 flow statistics: 1-day maximum, mean, and 7-day minimum. The computations involved are the same as the ones used in plotFlowSingle or in makeAnnualSeries

Usage

plot1of15(eList, yearStart, yearEnd, qf, istat, isBottom = FALSE)

Arguments

eList	named list with at least the Daily and INFO dataframes
yearStart	A numeric value for the year in which the graph should start
yearEnd	A numeric value for the year in which the graph should end
qf	a scale factor to convert discharge in cubic feet per second to mm/day, it is 86 / (drainage area in square kilometers)
istat	A numeric value selecting the flow statistic to be plotted, must be an integer from 1 to 8
isBottom	logical, if TRUE the graph is from the bottom row and thus needs x axis labels, if FALSE it does not need labels

Examples

eList <- Choptank_eList
plot1of15(eList, 1980, 2010, 0.2938476, 5)
