In googleVis: R Interface to Google Charts

Google Bubble Chart with R \Sexpr{googleChartName <- "bubblechart"} \Sexpr{gvisChartName <- "gvisBubbleChart"}

Description

The gvisBubbleChart function reads a data.frame and creates text output referring to the Google Visualisation API, which can be included into a web page, or as a stand-alone page.

Usage

gvisBubbleChart(
  data,
  idvar = "",
  xvar = "",
  yvar = "",
  colorvar = "",
  sizevar = "",
  options = list(),
  chartid
)

Arguments

data	a data.frame to be displayed as a bubble chart. The data has to have at least three columns for idvar, xvar, and yvar.
idvar	column name of data with the bubble
xvar	column name of a numerical vector in data to be plotted on the x-axis.
yvar	column name of a numerical vector in data to be plotted on the y-axis.
colorvar	column name of data that identifies bubbles in the same series. Use the same value to identify all bubbles that belong to the same series; bubbles in the same series will be assigned the same color. Series can be configured using the series option.
sizevar	values in this column are mapped to actual pixel values using the sizeAxis option.
options	list of configuration options, see: \Sexpr[results=rd]{gsub("CHARTNAME", googleChartName, readLines(file.path(".", "inst", "mansections", "GoogleChartToolsURLConfigOptions.txt")))} \Sexpr[results=rd]{paste(readLines(file.path(".", "inst", "mansections", "gvisOptions.txt")))}
chartid	character. If missing (default) a random chart id will be generated based on chart type and tempfile.

Details

A bubble chart is used to visualize a data set with 2 to 4 dimensions. The first two dimensions are visualized as coordinates, the 3rd as color and the 4th as size.

The bubble chart is rendered within the browser using SVG or VML and displays tips when hovering over points.

Value

\Sexpr[results=rd]{paste(gvisChartName)}

returns list of class \Sexpr[results=rd]{paste(readLines(file.path(".", "inst", "mansections", "gvisOutputStructure.txt")))}

Examples

bubble1 <- gvisBubbleChart(Fruits, idvar="Fruit", xvar="Sales", yvar="Expenses")
plot(bubble1)

## Set color and size
bubble2 <- gvisBubbleChart(Fruits, idvar="Fruit", xvar="Sales", yvar="Expenses",
                          colorvar="Location", sizevar="Profit",
                          options=list(hAxis='{minValue:75, maxValue:125}'))

plot(bubble2)

## Use year to color the bubbles
bubble3 <- gvisBubbleChart(Fruits, idvar="Fruit", xvar="Sales", yvar="Expenses",
                           colorvar="Year", sizevar="Profit",
                           options=list(hAxis='{minValue:75, maxValue:125}'))
plot(bubble3)

## Gradient colour example
bubble4 <- gvisBubbleChart(Fruits, idvar="Fruit", xvar="Sales", yvar="Expenses",
                          sizevar="Profit",
                          options=list(hAxis='{minValue:75,  maxValue:125}', 
                                  colorAxis="{colors: ['lightblue', 'blue']}"))
plot(bubble4)

## Not run: 
## Moving bubble chart over time, aka motion chart

M <- gvisMotionChart(Fruits, Fruit, Year)
plot(M)

## End(Not run)
