gr_plot_ridge: Ridgeline hydrograph plot

In tsamsonov/grwat: River Hydrograph Separation and Analysis

Ridgeline hydrograph plot

Description

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))
