Plots the timing (day of year and date) of portions of total annual flow of daily flow
values from a daily streamflow data set. Calculates statistics from all values from complete years, unless specified.
Data calculated using `calc_annual_flow_timing()`

function. Returns a list of plots.

plot_annual_flow_timing( data, dates = Date, values = Value, groups = STATION_NUMBER, station_number, percent_total = c(25, 33.3, 50, 75), water_year_start = 1, start_year, end_year, exclude_years, include_title = FALSE )

data | Data frame of daily data that contains columns of dates, flow values, and (optional) groups (e.g. station numbers).

dates | Name of column in |

values | Name of column in |

groups | Name of column in |

station_number | Character string vector of seven digit Water Survey of Canada station numbers (e.g. |

percent_total | Numeric vector of percents of total annual flows to determine dates. Default |

water_year_start | Numeric value indicating the month ( |

start_year | Numeric value of the first year to consider for analysis. Leave blank to use the first year of the source data. |

end_year | Numeric value of the last year to consider for analysis. Leave blank to use the last year of the source data. |

exclude_years | Numeric vector of years to exclude from analysis. Leave blank to include all years. |

include_title | Logical value to indicate adding the group/station number to the plot, if provided. Default |

day of year of 25-percent of total volumetric discharge

day of year of 33.3-percent of total volumetric discharge

day of year of 50-percent of total volumetric discharge

day of year of 75-percent of total volumetric discharge
