ch_polar_plot: Polar plot of daily streamflows

Description

Produces a polar plot similar to that used in Whitfield and Cannon, 2000. It uses output from the function ch_binned_MannWhitney or a data structure created using the function ch_polar_plot_prep.

Usage

ch_polar_plot(
  bmw,
  lcol1 = c("black", "gray50"),
  lcol2 = c("black", "gray50"),
  lfill = c("yellow", "green"),
  lsig = c("red", "blue")
)

Value

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

Arguments

bmw

output from ch_binned_MannWhitney

lcol1

line colour, default is c("black","gray50")

lcol2

point colour, default is c("black","gray50")

lfill

fill colour, default is c("yellow","green")

lsig

significance symbol colour, default is c("red","blue")
