plot,cm-method: Plot a cm Object

Description

Creates a multi-panel summary plot of data measured by a current meter.

Usage

# S4 method for cm
plot(
  x,
  which = c(1:2),
  type = "l",
  drawTimeRange = getOption("oceDrawTimeRange"),
  drawZeroLine = FALSE,
  mgp = getOption("oceMgp"),
  mar = c(mgp[1] + 1.5, mgp[1] + 1.5, 1.5, 1.5),
  small = 2000,
  main = "",
  tformat,
  debug = getOption("oceDebug"),
  ...
)

Arguments

x: a cm object.
which: list of desired plot types. These are graphed in panels running down from the top of the page. See “Details” for the meanings of various values of which.
type: type of plot, as for plot().
drawTimeRange: boolean that applies to panels with time as the horizontal axis, indicating whether to draw the time range in the top-left margin of the plot.
drawZeroLine: boolean that indicates whether to draw zero lines on velocities.
mgp: 3-element numerical vector to use for par(mgp), and also for par(mar), computed from this. The default is tighter than the R default, in order to use more space for the data and less for the axes.
mar: value to be used with par("mar").
small: an integer indicating the size of data set to be considered "small", to be plotted with points or lines using the standard plot() function. Data sets with more than small points will be plotted with smoothScatter() instead.
main: main title for plot, used just on the top panel, if there are several panels.
tformat: optional argument passed to oce.plot.ts(), for plot types that call that function. (See strptime() for the format used.)
debug: a flag that turns on debugging. Set to 1 to get a moderate amount of debugging information, or to 2 to get more.
...: Optional arguments passed to plotting functions.

Details

The panels are controlled by the which argument, as follows.

which=1 or which="u" for a time-series graph of eastward velocity, u, as a function of time.
which=2 or which="v" for a time-series graph of northward velocity, u, as a function of time.
which=3 or "progressive vector" for progressive-vector plot
which=4 or "uv" for a plot of v versus u. (Dots are used for small datasets, and smoothScatter for large ones.)
which=5 or "uv+ellipse" as the "uv" case, but with an added indication of the tidal ellipse, calculated from the eigen vectors of the covariance matrix.
which=6 or "uv+ellipse+arrow" as the "uv+ellipse" case, but with an added arrow indicating the mean current.
which=7 or "pressure" for pressure
which=8 or "salinity" for salinity
which=9 or "temperature" for temperature
which=10 or "TS" for a TS diagram
which=11 or "conductivity" for conductivity
which=20 or "direction" for the direction of flow
