In USGS-R/smwrGraphs: Graphing Functions

Plot Parameters

Description

Sets plot control list for groups of data (support function).

Usage

setGroupPlot(current, Grps = 1, name = "", what = "points",
  type = "solid", width = "standard", symbol = "circle",
  filled = TRUE, size = 0.09, color = "black")

Arguments

current	the plot parameters specified in the call to the high-level graphing function.
Grps	the number of groups.
name	the name associated with the group. See Details.
what	what kind of plot. Must be one of "points," symbols only; "lines," line segments connecting points only; "both," line segments connecting isolated symbols; "overlaid," line segments connecting points with symbols; "stairstep," stairstep line segments; or "vertical," vertical lines from the y-axis origin to the y value at each x value.
type	the type of line, if drawn. Must be one of "solid," "dashed," "dotted."
width	the width of line, if drawn. Must be one of "standard," resulting in a line width of about 0.7 points; "color," resulting in a line width of about 0.8 points; "bold," resulting in a line width of about 1. point; or "hairline" resulting in a line width of about 0.5 points. Note these values are doubled if the font argument to setPage is "PPT."
symbol	type symbol, if drawn. Must be one of "circle," "uptri" (upward pointing triangle), "plus," "x," "diamond," "downtri" (downward pointing triangle), "square," or "dot."
filled	logical, if TRUE, then fill the symbol. Valid only for symbol equal to "circle," "uptri," "diamond," "downtri," or "square."
size	the size of the symol in inches, if drawn.
color	the color of the plotted values for each group. Can be a named color, such as "black" or "gray50" or an RGB color like "#A09623."

Details

If the name component in the original call to the high-level plot is "Auto," then the description for the explanation is taken from the value in the Group argument in that call. Otherwise the user must specify a name for each group.

If the color component in the original call to the high-level plot is "Auto," then the colors for each group are based on a sequence of 15 colors that are easily distinguished from each other. If there are more than 15 groups, then a gray scale is used with no guarantee of easily distinguished colors.

Value

A list having two components:

current	a list like current with the defaults set
Explan	a list for creating an explanation
