Changing the width of bars and columns in googleVis

on |
Changing the plotting width in bar-, column- and combo-charts of googleVis works identical and is defined by the bar.groupWidth argument. The dot in the argument means that it has to be split in R into bar="{groupWidth:'10%'}".

Example

library(googleVis)
cc <- gvisColumnChart(head(Population,10), 
                      xvar="Country", yvar="Population",
                      options=list(seriesType="bars", legend="top",
                                   bar="{groupWidth:'10%'}",
                                   width=500, height=450),
                      chartid="thincolumns")
plot(cc)
