plot.wt: Plots wavelet transform

In Dasonk/SOWAS: Software for Wavelet Analysis and Synthesis

Description

This function plots objects of type "wt" (wavelet transform objects) from the functions wsp,wcs,wco. Modulus and (if possible) phase are plotted.

Usage

  plot.wt(wt, markt = -999, marks = -999, t1 = NULL,
    t2 = NULL, logscale = FALSE, phase = FALSE, units = "",
    plottitle = "", device = "screen", file = "wt",
    split = FALSE, color = TRUE, pwidth = 10, pheight = 5,
    labsc = 1.5, labtext = "", sigplot = 3, xax = NULL,
    xlab = NULL, yax = NULL, ylab = NULL)

Arguments

wt	Wavelet transformation object
markt	Vector of times to be marked by vertical dotted lines. When set to -999 (default), no lines are plotted.
marks	Vector of scales to be marked by horizontal dotted lines. When set to -999 (default), no lines are plotted.
t1	Starting time of the plot. If NULL (default), then the plot covers the entire range available
t2	Ending time of the plot. If NULL (default), then the plot covers the entire range available
logscale	When TRUE, the contours are plotted in logarithmic scale
phase	TRUE if phase is to be plotted
units	character string giving units of the data sets. Default: ""
plottitle	character string giving plot title
device	"screen" or "ps"
file	character string giving filename of graphical output without extension
split	when TRUE, modulus and phase are splitted into two files. Default: FALSE
color	TRUE (default): color plot, FALSE: gray scale
pwidth	width of plot in cm
pheight	height of plot in cm
labsc	scale of labels, default: 1, for two-column manuscripts: 1.5, for presentations: >2
labtext	puts a label in upper left corner of the plot
sigplot	0: no significance test plotted, 1: results from pointwise test, 2: results from areawise test, 3: results from both tests

Details

This function has to be called with an object of type "wt" (wavelet transformation object, output from wsp,wcs,wco). It calls plotwt(). When cv=0 or -1 is chosen, no critical values are plotted. The cone of influence is marked by black lines. If cv is a vector, the routine assumes that every value represents a critical value, which is constant in scale. If cv is a matrix, it assumes every row to contain scale dependent critical values, each row stands for one significance level. Values outside the cone of influence should be interpreted very carefully, as they result from a significant contribution of zero padding at the beginning and the end of the time series. For a better visualization, additional dotted lines marking distinct times or scales might be plotted by providing the vectors markt and marks.
