chart.Scatter: wrapper to draw scatter plot with sensible defaults

Description

Draws a scatter chart. This is another chart "primitive", since it only contains a set of sensible defaults. This function is intended to be used in a wrapper that is written for a particular purpose. This is just a handy way to standardize the formatting of multiple charts.

Usage

chart.Scatter(x, y, reference.grid = TRUE, main = "Title", ylab = NULL, xlab = NULL, xlim = NA, ylim = NA, colorset = 1, symbolset = 1, darken = FALSE, legend.loc = NULL, ylog = FALSE, ...)

Arguments

x

data for the x axis, can take matrix,vector, or timeseries

y

data for the y axis, can take matrix,vector, or timeseries

reference.grid

if true, draws a grid aligned with the points on the x and y axes

main

set the chart title, same as in plot

ylab

set the y-axis label, as in plot

xlab

set the x-axis label, as in plot

xlim

set the x-axis limit, same as in plot

ylim

set the y-axis limit, same as in plot

colorset

color palette to use, set by default to rational choices

symbolset

from pch in plot, submit a set of symbols to be used in the same order as the data sets submitted

darken

if true, draws the chart elements in "darkgray" rather than "gray". Makes it easier to print for some printers.

legend.loc

places a legend into one of nine locations on the chart: bottomright, bottom, bottomleft, left, topleft, top, topright, right, or center.

ylog

TRUE/FALSE set the y-axis to logarithmic scale, similar to plot, default FALSE

...

any other passthru parameters

Value

• Draws a graph of type "scatter" with some sensible defaults.
