patternbar: Plot a bar chart using patterns and colors to fill the bars.

In patternplot: Versatile Pie Charts, Ring Charts, Bar Charts and Box Plots using Patterns, Colors and Images

Description

The patternbar function is a tool for creating versatile bar charts by filling the bars with colors and patterns.

Usage

patternbar(
  data,
  x,
  y,
  group = NULL,
  xlab = "",
  ylab = "",
  label.size = 3.5,
  vjust = -1,
  hjust = -1,
  pattern.type,
  pattern.line.size = rep(5, ifelse(is.null(group), length(x), length(unique(group)))),
  pattern.color = rep("black", ifelse(is.null(group), length(x),
    length(unique(group)))),
  background.color = rep("white", ifelse(is.null(group), length(x),
    length(unique(group)))),
  frame.color = rep("black", ifelse(is.null(group), length(x), length(unique(group)))),
  frame.size = 1,
  pixel = 20,
  density = rep(7, ifelse(is.null(group), length(x), length(unique(group)))),
  legend.type = "h",
  legend.h = 6,
  legend.x.pos = 1.1,
  legend.y.pos = 0.49,
  legend.w = 0.2,
  legend.pixel = 20,
  bar.width = 0.9
)

Arguments

data	the data to be used.
x	the variable used on x axis.
y	the variable used on y axis.
group	the variable used as the second grouping variable on x axis.
xlab	a character string to give x axis label.
ylab	a character string to give y axis label.
label.size	the font size of legend labels shown above the bars.
vjust	the vertical distance of labels from the top border of each bar.
hjust	the horizontal distance of labels from the top border of each bar.
pattern.type	a vector of patterns to be filled in the bars The pattern types include: 'blank', 'bricks', 'vdashes', 'hdashes', 'crosshatch','dots', 'grid','hlines','nelines', 'nwlines', 'vlines', 'waves' and more.
pattern.line.size	a vector of numeric values, the line size for the lines/dots of patterns.
pattern.color	a vector of colors for the lines/dots of patterns.
background.color	a vector of colors to be filled in the bars.
frame.color	the color for the borders of bars.
frame.size	a numeric value, the line size for the borders of bars.
pixel	a numeric value, the pixel resolution of bar chart.
density	a numeric vector, the density for the lines/dots of patterns.
legend.type	if legend.type='h', the layout of legends is horizontal; if legend.type='v', the layout of legends is vertical.
legend.h	a numeric value to change the height of legend boxes.
legend.x.pos	a numeric value to change the position of legends on x axis.
legend.y.pos	a numeric value to change the position of legends on y axis.
legend.w	a numeric value to change the width of legends.
legend.pixel	a numeric value to change pixel of legends.
bar.width	a numeric value to change the width of the bars.
