plotHydroConc

Description

Function to generate a two panel graph with hydrograph(s) in the top panel and concentration or other water quality parameter (e.g. flux) in the lower panel with corresponding date axes for the top and bottom panels

Usage

plotHydroConc(
  Q,
  QVars,
  QDateVars,
  smooth,
  sites,
  Conc,
  CVars,
  CDateVar,
  CVarsDisplay,
  dates,
  sampDates,
  eventDates,
  Qcols,
  Ccols,
  leftBuffer,
  rightBuffer,
  concLines = TRUE,
  Qylab = "Discharge (cfs)",
  Cylab = "Concentration",
  title1 = "Flow",
  title2 = "and concentration"
)

Arguments

Q	dataframe list with flow variables and POSIXct date variables. The list contains one file per Q record (usually one dataframe per site).
QVars	vector of strings that signify the column names that represent the flow variables in the dataframes defined in Q
QDateVars	vector of strings that signify the column names that represent the POSIXct date variables in the dataframes defined in Q
smooth	Boolean vector to trigger lowess smooth in graphing rather than direct flow graphing (useful for sites impacted by seiche)
sites	Sites for Q data. This will be used in the legend of the Q panel
Conc	dataframe with variables to be plotted in the second panel
CVars	vector of strings that represent the variables in Conc to include in the graphs in the second panel
CDateVar	column name in Conc for sample dates and times in POSIXct
CVarsDisplay	variable names from CVars to be displayed on the legend
dates	dataframe with beginning and ending sample dates and times and beginning and ending hydrograph dates and times
sampDates	vector of length two that contains strings representing the column names for beginning and ending dates and times for samples
eventDates	vector of length two that contains strings representing the column names for beginning and ending dates and times for the sampling event. This is the hydrograph segment that the samples are intended to represent (often a runoff hydrograph or a baseflow period)
Qcols	vector of colors for ploting hydrographs from the Q dataframe
Ccols	vector of colors for plotting from the Conc dataframe
leftBuffer	time in days to plot before the beginning of the event period
rightBuffer	time in days to plot after the end of the event period
concLines	Boolean variable to signify whether a line should be drawn between consecutive data points from the Conc dataframe in the second graph panel
Qylab	y-axis label for the first graph panel
Cylab	y-axis label for the second graph panel
title1	Line 1 of plot title
title2	Line 2 of plot title
