plot.ctd.scan: Plot seawater data in a low-level fashion

Description

Plot CTD data as time-series against scan number, to help with trimming extraneous data from a CTD cast.

Usage

plot.ctd.scan(x, name = "scan", 
 S.col = "darkgreen", T.col= "darkred", p.col = "blue",
 adorn=NULL, mgp=getOption("oceMgp"), ...)

Arguments

x

A cdt object, e.g. as read by read.ctd.

name

name of variable for x axis

S.col

colour for salinity

T.col

colour for temperature

p.col

colour for pressure

adorn

list of character strings containing commands to be executed for the panels. If the number matches the number of panels, then the strings are applied to the appropriate panels, as they are drawn from top-left to bottom-right. If only a sing

mgp

...

optional arguments passed to plotting functions.

Details

Plots ctd data as time-series against the scan number, as an aide to trimming to downcasts, etc.
