)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().- xlim, ylim
optional limit to the x and y axes, passed to
oce.plot.ts()for time-series plots.- xaxs, yaxs
optional controls over the limits of the x and y axes, passed to
oce.plot.ts()for time-series plots. These values default to"r", meaning to use the regular method of extend the plot past its normal limits. It is common to use"i"to make the graph extend to the panel limits.- 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 forpar(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 thansmallpoints will be plotted withsmoothScatter()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. (Seestrptime()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=1orwhich="u"for a time-series graph of eastward velocity,u, as a function of time.which=2orwhich="v"for a time-series graph of northward velocity,u, as a function of time.which=3or"progressive vector"for progressive-vector plotwhich=4or"uv"for a plot ofvversusu. (Dots are used for small datasets, and smoothScatter for large ones.)which=5or"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=6or"uv+ellipse+arrow"as the"uv+ellipse"case, but with an added arrow indicating the mean current.which=7or"pressure"for pressurewhich=8or"salinity"for salinitywhich=9or"temperature"for temperaturewhich=10or"TS"for a TS diagramwhich=11or"conductivity"for conductivitywhich=20or"direction"for the direction of flow
