回答1:

Chartkick uses Google Visualization library to draw charts. Here is options description: https://developers.google.com/chart/interactive/docs/gallery/piechart?csw=1#Example

pie_chart graph_data, { pieSliceText: 'value' }

Here is the syntax I found that worked:

<%= pie_chart @my_data, library: { pieSliceText: 'value' } %>
