R Documentation

Horizon hydrograph plot

Description

A convenient wrapper around ggHoriPlot::geom_horizon() to visualize multiple river hydrographs at once.

Usage

gr_plot_hori(df, years, pal = "Blues", rev = TRUE, scale = 6, print = TRUE)

Arguments

`df`	`data.frame` with date (1st) and runoff (2nd) columns.
`years`	Integer vector of years to be plotted.
`pal`	Numeric or character string. Color palette identifier passed to `ggplot2::scale_fill_distiller()`.
`rev`	Boolean. Reverse the palette? Defaults to `FALSE`.
`scale`	Numeric scale factor passed to `ggHoriPlot::geom_horizon()`. Defaults to `6`.
`print`	Boolean. Print plot? Defaults to `TRUE`. Use `FALSE` if you want to tweak the plot aesthetics before plotting.

Value

ggplot2 object representing multiple river hydrographs at once using the horizon plot approach

Examples

if (require("ggHoriPlot") && require("ggthemes")) {
  
  library(grwat)
  
  data(spas) # example Spas-Zagorye data is included with grwat package
  
  # separate
  sep = gr_separate(spas, params = gr_get_params(reg = 'center'))
  
  # horizon plot for selected years
  gr_plot_hori(sep, years = 1960:1980)
  
}
