2.7 Setting options

Setting the various options of a googleVis objects can be a bit cumbersome at

ﬁrst. The options follow those of the Google Charts API and can be set via a named

list using the argument options. In the following example we create a line chart

and set various options

, see the output in Figure 5.

Figure 5: A line chart with various options set.

R> df <- data.frame(country=c("US", "GB", "BR"),

+ val1=c(1,3,4), val2=c(23,12,32))

R> Line <- gvisLineChart(df, xvar="country", yvar=c("val1","val2"),

+ options=list(

+ title="Hello World",

+ titleTextStyle="{color:'red',

+ fontName:'Courier',

+ fontSize:16}",

+ backgroundColor="#D3D3D3",

+ vAxis="{gridlines:{color:'red', count:3}}",

+ hAxis="{title:'Country', titleTextStyle:{color:'blue'}}",

+ series="[{color:'green', targetAxisIndex: 0},

+ {color: 'orange',targetAxisIndex:1}]",

+ vAxes="[{title:'val1'}, {title:'val2'}]",

+ legend="bottom",

+ curveType="function",

+ width=500,

+ height=300

Please refer to the help ﬁle of the individual googleVis functions, as the options can vary

from chart to chart.
