Plot TOXSWA surface water concentrations — plot.TOXSWA

Plot TOXSWA hourly concentrations of a chemical substance in a specific segment of a TOXSWA surface water body.

# S3 method for TOXSWA_cwa
plot(
  x,
  time_column = c("datetime", "t", "t_firstjan", "t_rel_to_max"),
  xlab = "default",
  ylab = "default",
  add = FALSE,
  threshold_factor = 1000,
  thin_low = 1,
  total = FALSE,
  LC_TIME = "C",
  ...
)

Arguments

x: The TOXSWA_cwa object to be plotted.
time_column: What should be used for the time axis. If "t_firstjan" is chosen, the time is given in days relative to the first of January in the first year.
xlab, ylab: Labels for x and y axis.
add: Should we add to an existing plot?
threshold_factor: The factor by which the data have to be lower than the maximum in order to get thinned for plotting (see next argument).
thin_low: If an integer greater than 1, the data close to zero (smaller than 1/threshold_factor of the maximum) in the series will be thinned by this factor in order to decrease the amount of data that is included in the plots
total: Should the total concentration in water be plotted, including substance sorbed to suspended matter?
LC_TIME: Specification of the locale used to format dates
...: Further arguments passed to plot if we are not adding to an existing plot
