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