#' #' @title Base clock plot function
#' #'
#' #' @description
#' #' Create a "clock plot" showing PM2.5 data for a single day for the given
#' #' monitors. A colored bar curves around in a clockwise manner with 12/4 of the
#' #' bar colored for each hour of the local time day.
#' #'
#' #' This function will typically be called from \code{\link{clockPlot}} which
#' #' presents a simplified interface.
#' #'
#' #' Room for annotations can be created by setting \code{plotRadius = 1.2}.
#' #'
#' #' @param ws_monitor \emph{ws_monitor} object containing a single monitor.
#' #' @param startdate Desired start date (integer or character in Ymd format
#' #' or \code{POSIXct}).
#' #' @param enddate Desired end date (integer or character in Ymd format
#' #' or \code{POSIXct}).
#' #' @param gapFraction Fraction of the circle used as the day boundary gap.
#' #' @param centerColor Color used for the center of the circle.
#' #' @param gapColor Color used for the day-break gap.
#' #' @param plotRadius Full radius of the plot.
#' #' @param dataRadii Inner and outer radii for the data portion of the plot [0:1].
#' #' @param shadedNight Add nighttime shading.
#' #' @param hoursPerTick Add tick marks every # hours. Defaults to no ticks.
#' #' @param solarLabels Add sunrise/sunset labels.
#' #' @param colorPalette Palette function to convert monitor values into colors.
#' #' @param labelScale Scale factor applied to labels.
#' #' @param title Optional title for the plot.
