# Plot TOXSWA surface water concentrations
Plot TOXSWA hourly concentrations of a chemical substance in a specific
segment of a TOXSWA surface water body.
## Usage
``` r
# S3 method for class '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
