Discharge axis tick generation
Usage
generalAxis(x, maxVal, minVal, units = NA, logScale = FALSE,
tinyPlot = FALSE, padPercent = 5, concentration = TRUE, concLab = 1,
usgsStyle = FALSE, prettyDate = TRUE)Arguments
- x
vector to create scale about
- maxVal
number maximum value on returned scale
- minVal
number minimum value on returned scale
- units
character concentration units. Typically found in INFO$param.units.
- logScale
logical whether or not to return a log scale
- tinyPlot
logical
- padPercent
number used to pad the max and min if not specified
- concentration
logical if concentration=TRUE, labels returned as concentration units, otherwise flux units.
- concLab
object of concUnit class, or numeric represented the short code, or character representing the descriptive name. By default, this argument sets concentration labels to use either Concentration or Conc (for tiny plots). Units are taken from the eList$INFO$param.units. To use any other words than "Concentration" see
vignette(topic = "units", package = "EGRET").- usgsStyle
logical option to use USGS style guidelines. Setting this option to TRUE does NOT guarantee USGS compliance. It will only change automatically generated labels
- prettyDate
logical use 'pretty' limits for date axis if TRUE, or force the yearStart/yearEnd as limits if FALSE

Daily <- getDaily(eList)
INFO <- getInfo(eList)
x <- Daily$Q
max <- max(x)
min <- 0
units <- INFO$param.units
