Horizon hydrograph plot — gr_plot

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)
  
}
