推荐答案

Chartkick gem是 Google图表的包装。通过使用库选项，您可以指定要在传奇中显示的值，并设置其他配置选项。

Chartkick gem is a wrapper on top of Google Charts. By using library option you can specify what value to show in the legend and set other configuration options.

类似这样：

<%= pie_chart visits.group(:country).count, library: {pieSliceText:
'value-and-percentage'} %>
