ch_booth_plot {CSHShydRology}R Documentation

Create Booth plot of peaks over a threshold

Description

A Booth plot is a plot of peaks over threshold flood events with duration on the horizontal and either magnitude (default) or volume on the vertical axis.

Usage

ch_booth_plot(events, threshold, title, type = "mag", colour1 = 1, colour2 = 1)

Arguments

events

A data frame of POT events from the function ch_get_peaks

threshold

The threshold used by ch_get_peaks

title

Plot title

type

The plot type, either mag (magnitude, the default) or vol (volume)

colour1

A vector of length 12 with line colours of rings or symbols. Defaults to those used by Booth.

colour2

A vector of length 12 with fill colours of rings or symbols. Defaults to those used by Booth.

Value

No value is returned; a standard R graphic is created.
