如何在rCharts中向hPlot添加自定义工具提示

I'm able to make a great hPlot using the following code:

我可以使用以下代码创建一个很棒的hPlot：

h1<-hPlot(x = "MedianAge", 
      y = "AnnualPopulationGrowth", 
      data = df, 
      type = "bubble", 
      size="AdolescentFertilityRate", group = "continent")
h1$title(text='Median Age vs Annual Population Growth in 2010')
h1

However, I have a field in my data.frame df, called "Name", that I want to display. I tried adding the following line:

但是，我在data.frame df中有一个字段，名为“Name”，我想显示它。我尝试添加以下行：

h1<-hPlot(x = "MedianAge", 
  y = "AnnualPopulationGrowth", 
  data = df, 
  type = "bubble", 
  size="AdolescentFertilityRate", group = "continent")
h1$title(text='Median Age vs Annual Population Growth in 2010')
h1

However that doesn't work. Variations on this line like:

然而，这不起作用。这条线的变化如：

h1$tooltip(formatter("#! function(d) {return d.Name} !#"))

also do not work. Any help getting the name of the country to pop up in the tooltip would be awesome, thanks.

也不行。任何有助于在工具提示中弹出国家名称的帮助都会很棒，谢谢。

Here is a minimal example:

这是一个最小的例子：

library(rCharts)
# data
df <- data.frame(x = 1:10, y = rnorm(10), s = rnorm(10), z = letters[1:10])

# create plot object
p <- hPlot(y ~ x, data = df, size = "s", type = "bubble")

# fix data format
p$params$series[[1]]$data <- toJSONArray(df, json = F)

# add tooltip formatter
p$tooltip(formatter = "#! function() {return(this.point.z);} !#")

# show
p
