createBubblechart: Create Bubble Chart type of plot.

In teradata-aster-field/toaster: Big Data in-Database Analytics that Scales with Teradata Aster Distributed Platform

Description

Create a bubble chart that utilizes three dimensions of data. It is a variation of the scatter plot with data points replaced with shapes ("bubbles"): x and y are bubble location and z is its size. It can optionally assign data points labels and fill shapes with colors.

Usage

createBubblechart(data, x, y, z, label = z, fill = NULL, facet = NULL,
  ncol = 1, facetScales = "fixed", xlim = NULL, baseSize = 12,
  baseFamily = "sans", shape = 21, shapeColour = "black",
  scaleSize = TRUE, shapeSizeRange = c(3, 10), shapeMaxSize = 100,
  paletteValues = NULL, palette = "Set1", title = paste("Bubble Chart by",
  fill), subtitle = NULL, xlab = x, ylab = y, labelSize = 5,
  labelFamily = "", labelFontface = "plain", labelColour = "black",
  labelVJust = 0.5, labelHJust = 0.5, labelAlpha = 1, labelAngle = 0,
  legendPosition = "right", sizeGuide = FALSE, fillGuide = "colorbar",
  defaultTheme = theme_tufte(base_size = baseSize, base_family = baseFamily),
  themeExtra = NULL)

Arguments

data	data frame contains data computed for bubblechart
x	name of a column containing x variable values
y	name of a column containing y variable values
z	name of a column containing bubble size value
label	name of a column containing bubble label
fill	name of a column with values to use for bubble colours
facet	vector of 1 or 2 column names to split up data to plot the subsets as facets. If single name then subset plots are placed next to each other, wrapping with ncol number of columns (uses facet_wrap). When two names then subset plots vary on both horizontal and vertical directions (grid) based on the column values (uses facet_grid).
ncol	number of facet columns (applies when single facet column supplied only - see parameter facet).
facetScales	Are scales shared across all subset plots (facets): "fixed" - all are the same, "free_x" - vary across rows (x axis), "free_y" - vary across columns (Y axis, default), "free" - both rows and columns (see in facet_wrap parameter scales )
xlim	a vector specifying the data range for the x scale and the default order of their display in the x axis.
baseSize	theme base font size
baseFamily	theme base font family
shape	bubble shape
shapeColour	colour of shapes
scaleSize	logical if TRUE then scale the size of shape to be proportional to the value, if FALSE then scale the area.
shapeSizeRange	bubble size range (applies only when scaleSize = TRUE)
shapeMaxSize	size of largest shape (applies only when scaleSize = FALSE)
paletteValues	actual palette colours for use with scale_fill_manual (if specified then parameter palette is ignored)
palette	Brewer palette name - see display.brewer.all in RColorBrewer package for names
title	plot title.
subtitle	plot subtitle.
xlab	a label for the x axis, defaults to a description of x.
ylab	a label for the y axis, defaults to a description of y.
labelSize	size of labels
labelFamily	label font name or family name
labelFontface	label font face (c("plain","bold","italic","bold.italic"))
labelColour	color of labels
labelVJust	position of the anchor (0=bottom edge, 1=top edge), can go below 0 or above 1
labelHJust	position of the label anchor (0=left edge, 1=right edge), can go below 0 or above 1
labelAlpha	the transparency of the text label
labelAngle	the angle at which to draw the text label
legendPosition	the position of legends. ("left", "right", "bottom", "top", or two-element numeric vector). "none" is no legend.
sizeGuide	Name of guide object, or object itself for the z (bubble size). Typically "legend" name or object guide_legend.
fillGuide	Name of guide object, or object itself for the fill. Typically "colorbar" name or object guide_colourbar.
defaultTheme	plot theme settings with default value theme_tufte. More themes are available here: ggtheme (by ggplot2) and ggthemes.
themeExtra	any additional theme settings that override default theme.

Value
