gvisScatterChart - hAxis.title 和 vAxis.title 未出现在图上

Question

hAxis.title 和 vAxis.title 选项似乎没有为包 googleVis.

中的 gvisScatterChart 设置轴标题

plot(gvisScatterChart(data.frame(x = 3, y = 4), options=list(hAxis.title = 'foo')))

"foo" 没有显示为横轴标题。

Answer 1

您应该以字典形式的 JSON 对象格式将选项传递给 hAxis：

plot(gvisScatterChart(data.frame(x = 3, y = 4), options=list(hAxis="{title:'foo'}")))

请参阅 help page 底部的示例以及 hAxis 下的示例：

a JSON object. Default null. An object with members to configure various horizontal axis elements. To specify properties of this object, you can use object literal notation, as shown here:
{title: 'Hello', titleTextStyle: {color: '#FF0000'}}
