# wavPlot: Wavelet plots In wavScalogram: Wavelet Scalogram Tools for Time Series Analysis

## Description

This function plots a function of two variables (usually times and scales). It is suitable for plotting windowed scalograms, windowed scalogram differences, wavelet coherences and windowed scale indices.

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13``` ```wavPlot(Z, X = NULL, Y = NULL, Ylog = FALSE, Yrev = TRUE, zlim = NULL, coi = NULL, rdist = NULL, sig95 = NULL, sig05 = NULL, Xname = "X", Yname = "Y", Zname = "Z") ```

## Arguments

 `Z` A matrix with the images of the function to be plotted. `X` A vector with x-coordinates (times). `Y` A vector with y-coordinates (scales). `Ylog` Logical. Considers logarithmic scale for the y-axis. `Yrev` Logical. Considers reverse the y-axis. `zlim` A vector of length 2 with the limits for the z-axis (the color bar). `coi` A vector of size `length(X)` with the y-coordinates of the frontier of the cone of influence. `rdist` Numeric. Only for WSD plots, margin in the y-axis where appear border effects. `sig95` Logical matrix with the same size as Z. TRUE if the corresponding point in Z is inside the significance at 95%. `sig05` Logical matrix with the same size as Z. TRUE if the corresponding point in Z is inside the significance at 5%. `Xname` A string with the name of the x-axis. `Yname` A string with the name of the y-axis. `Zname` A string with the name of the function.

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13``` ```nt <- 1500 time <- 1:nt sd_noise <- 0.2 #% In BolÃ³s et al. 2017 Figure 1, sd_noise = 1. signal1 <- rnorm(n = nt, mean = 0, sd = sd_noise) + sin(time / 10) signal2 <- rnorm(n = nt, mean = 0, sd = sd_noise) + sin(time / 10) signal2[500:1000] = signal2[500:1000] + sin((500:1000) / 2) ## Not run: wsd <- wsd(signal1 = signal1, signal2 = signal2, mc_nrand = 10, makefigure = FALSE) wavPlot(Z = -log2(wsd\$wsd), X = wsd\$t, Y = wsd\$scales, Ylog = TRUE, coi = wsd\$coi, rdist = wsd\$rdist, sig95 = wsd\$signif95, sig05 = wsd\$signif05, Xname = "Time", Yname = "Scale", Zname = "-log2(WSD)") ## End(Not run) ```
