plot_cont: Contour plot of only simulation results of a water quality variable.

Description

Contour plot a matrix of values of a water quality variable,

Usage

plot_cont(
  sim,
  sim.start,
  sim.end,
  legend.title,
  min.depth,
  max.depth,
  by.value,
  nlevels
)

Value

This function returns a filled.contour object.

Arguments

sim

a matrix of simulated variables. This matrix can be generated by running the "interpol" function.

sim.start, sim.end

the start and end dates of the simulation period for the DYRESM-CAEDYM model run of interest. The date format must be "%Y-%m-%d".

legend.title

the legend title of the contour figure.

min.depth, max.depth, by.value

minimum and maximum depths used to be the start of y axis of the contour plot, at the increment of by.value.

nlevels

Number of levels which are used to partition the range of simulation variable.

Details

This function is NOT based on ggplot2. To save the produced figure, users can use functions like png, bmp, jpeg, etc.

Examples

sim <- matrix(c(28,28,28,27,25,24,12,13,14,15,16,17),
              nrow = 6,
              ncol = 2)

# contour plot of the sim data frame
  p <- plot_cont(sim = sim,
            sim.start = "2020-01-01",
            sim.end = "2020-01-02",
            legend.title = "T \u00B0C",
            min.depth = 0, max.depth = 5, by.value = 1,
            nlevels = 20)
