Ridgeline hydrograph plot — gr_plot

A convenient wrapper around ggridges::geom_ridgeline() to visualize multiple river hydrographs at once.

Usage

gr_plot_ridge(
  df,
  years,
  pal = 4,
  rev = FALSE,
  scale = 0.01,
  alpha = 0.8,
  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 ggridges::geom_ridgeline(). Defaults to 0.01.
alpha: Numeric opacity value of the ridgeline plot. Defaults to 0.8.
print: Boolean. Print plot? Defaults to TRUE. Use FALSE if you want to tweak the plot aesthetics before plotting.

Value

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

Examples

if (require("ggridges")) {
  
  library(grwat)
  
  data(spas) # example Spas-Zagorye data is included with grwat package
  
  # separate
  sep = gr_separate(spas, params = gr_get_params(reg = 'center'))
  
  # ridgline plot for selected years
  gr_plot_ridge(sep, years = c(1960, 1965, 1989, 2001, 2012)) 

}
