HydroPlot: Hydrological plot of concurrent discharge and precipitation

In UKFE: UK Flood Estimation

Hydrological plot of concurrent discharge and precipitation

Description

Plots concurrent precipitation and discharge with precipitation along the top and discharge along the bottom

Usage

HydroPlot(
  x,
  Title = "Concurrent Rainfall & Discharge",
  from = NULL,
  to = NULL,
  adj.y = 1.5,
  plw = 1,
  qlw = 1.8,
  Return = FALSE
)

Arguments

x	a data.frame with three columns in the order of date (or POSIXct), precipitation, and discharge
Title	a character string. The user chosen plot title. The default is "Concurrent Rainfall & Discharge"
from	a starting time for the plot. In the form of a date or POSIXct object. The default is the first row of x
to	an end time for the plot. In the form of a date or POSIXct object. The default is the last row of x
adj.y	a numeric value to adjust the closeness of the preciptation and discharge in the plot. Default is 1.5. A lower value brings them closer and a larger value further apart
plw	a numeric value to adjust the width of the precipitation lines. Default is one. A larger value thickens them and vice versa
qlw	a numeric value to adjust the width of the discharge line. Default is 1.8. A larger value thickens them and vice versa
Return	a logical argument with a default of FALSE. If TRUE the data-frame of time, precipitation, and flow is returned

Details

The input of x is a dataframe with the first column being time. If the data is sub daily this should be class POSIXct with time as well as date.

Value

A plot of concurrent precipitation and discharge. With the former at the top and the latter at the bottom. If the Return argument equals true the associated data-frame is also returned.

Examples

#Plot the Thames precipitation and discharge for the 2013 hydrological year,
#adjusting the y axis to 1.8.
HydroPlot(ThamesPQ, from = "2013-10-01", to = "2014-09-30", adj.y = 1.8)
