Horizon hydrograph 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)
  
}

#> Warning: Using the `size` aesthetic in this geom was deprecated in ggplot2 3.4.0.
#> ℹ Please use `linewidth` in the `default_aes` field and elsewhere instead.
#> ℹ The deprecated feature was likely used in the grwat package.
