chartkick.js工具提示货币格式

Question

我在Google图表中使用了chartkick.js。我的问题是关于如何在工具提示中更改格式，例如货币格式。

电流：

在Highchrats，我们可以使用：

Highcharts.setOptions({
    global: {
      useUTC: false,
    },
    lang: {
      decimalPoint: ',',
      thousandsSep: '.'
    }
  });

然后

 tooltip: {
    pointFormat: "Value: {point.y:.2f} mm"
 }

我的图片代码如下：

   data = [
   {"name":"2015", "data": gon.serie1},
   {"name":"2014", "data": gon.serie2}];

   new Chartkick.LineChart("chart-1", data, {
     "library":
     {
       "backgroundColor" : "white"
     },
     "discrete": true
   });

如何使用googlechart适配器为chartkick.js
