plotNLines: Plot many lines in one plot

In JBTools: Misc Small Tools and Helper Functions for Other Code of J. Buttlar

Description

plotNLines function uses different techniques to visualize many line plots on one display.

Usage

plotNLines(x.data = matrix(1:dim(y.data)[2], ncol = dim(y.data)[2], 
    nrow = dim(y.data)[1], byrow = TRUE), y.data, option = c("normal", 
    "diff.scales", "stacked")[1], n.lines.max = 30, grid = FALSE, 
    scale = 1, plot.scale = TRUE, function.add = function() (1), 
    bgc = "white", pch.axlink = 1, type = "l", colors = c(), 
    xlim = c(), ylim = c(), xlab = c(), ylab = c(), labels = c(), 
    lty = 1, title, yaxt = "s", ...)

Arguments

x.data
y.data	numeric matrix/data frame: y-values with one series of values per row
option	character: which type of plot to use (see details)
n.lines.max	integer: only for 'stacked plots': how many lines to draw per panel
grid	logical: only for 'stacked plots': whether to draw a primitive grid
scale	numeric: only for 'stacked plots': scale factor to scale the y scale of the stacked plots
plot.scale	TRUE: only for 'stacked plots': whether to add a small scale showing the y axis scale
function.add	function: only for 'stacked plots': function to call after plotting the individual panels
bgc	color: color of the plot background
pch.axlink	integer: only for 'stacked plots': pch value for the symbol that links each line to its x-axis
type	standard plotting parameter
colors	colors to use for the different series
xlim	standard plotting parameter
ylim	standard plotting parameter
xlab	standard plotting parameter
ylab	standard plotting parameter
labels	standard plotting parameter
lty	standard plotting parameter
title	standard plotting parameter
yaxt	standard plotting parameter
...	further arguments passed to the plot() calls

Details

Many parameters are identical to standard plotting parameters (see ?par,?plot) and are not explained here. The function offers three options: 'normal': plots all plots in one coordinate system colored according to colors 'diff scales': plots all plots in the same region but uses different y axis scales. The visibility may be limited to ~7 plots. 'stacked': plots many plots in one region, all shifted vertically a bit to increase visibility. This allows for the easy comparison of many similar plots (e.g. time series) but reduces the details that are visible.
