Plot of the discharge time series

Description

Part of flowHistory component. Allows discharge record to only show those discharges above a given threshold

Although there are a lot of optional arguments to this function, most are set to a logical default.

Data come from named list, which contains a Daily dataframe with the daily flow data, and an INFO dataframe with metadata.

plotQTimeDaily(eList, yearStart = NA, yearEnd = NA, qLower = NA,
  qUnit = 1, logScale = FALSE, tinyPlot = FALSE, printTitle = TRUE,
  lwd = 3, col = "red", cex.main = 1.2, cex.lab = 1.2,
  customPar = FALSE, prettyDate = TRUE, ...)

Arguments

eList

named list with at least the Daily and INFO dataframes

yearStart

numeric indicating the starting year for the graph

yearEnd

numeric indicating the ending year for the graph (should be a time in decimal years that is after the last observations to be plotted)

qLower

numeric specifying the lower bound on discharges that are to be plotted, must be in the units specified by qUnit, default is NA (lower bound is zero)

qUnit

object of qUnit class. printqUnitCheatSheet, or numeric represented the short code, or character representing the descriptive name. Default is qUnit=1 (cubic feet per second)

logScale

logical whether or not to use a log scale in the y axis. Default is FALSE.

tinyPlot

logical variable, if TRUE plot is designed to be short and wide, default is FALSE.

printTitle

logical variable if TRUE title is printed, if FALSE title is not printed (this is best for a multi-plot figure)

lwd

line width, a positive number, defaulting to 1

col

specification for the default plotting color

cex.main

magnification to be used for main titles relative to the current setting of cex

cex.lab

magnification to be used for x and y labels relative to the current setting of cex

customPar

logical defaults to FALSE. If TRUE, par() should be set by user before calling this function (for example, adjusting margins with par(mar=c(5,5,5,5))). If customPar FALSE, EGRET chooses the best margins depending on tinyPlot.

prettyDate

logical use 'pretty' limits for date axis if TRUE, or force the yearStart/yearEnd as limits if FALSE

...

arbitrary graphical parameters that will be passed to genericEGRETDotPlot function (see ?par for options)
