Plot a longitudinal water quality profile across reservoir segments

Source: R/plot.R
ok_plot_segments.Rd

ok_plot_segments() visualises the spatial gradient in water quality from riverine to lacustrine zones of a multi-segment reservoir, using the output of ok_segment_summary() or ok_segment_chain().

Usage

ok_plot_segments(
  segment_data,
  metrics = c("tp_inlake_ugl", "chla_ugl", "secchi_m", "tsi_mean"),
  lake_name = NULL
)

Arguments

segment_data

Either a named list of okBATHTUB objects from ok_segment_chain(), or a data frame from ok_segment_summary().

metrics

Character vector. Which metrics to plot. Any subset of c("tp_inlake_ugl", "chla_ugl", "secchi_m", "tsi_mean", "tp_retention_pct"). Default: first four.

lake_name

Character. Lake name for the plot title.

Value

A ggplot2 object.
