google-visualization - Google image pie chart labels not working

Question

I am using the old static Google Chart API to generate a pie chart. The URL I am using is

https://chart.googleapis.com/chart?cht=p&chs=150x150&chd=t:1,2,3&chl=a|b|c

This URL contains the required parameter – chl – for labels, specified in the documentation (https://developers.google.com/chart/image/docs/gallery/pie_charts#pie_chart_label)

However, the image comes back with only lines pointing to the slices, not labels. Any help would be appreciated.

Answer 1

问题已解决：chs参数中的宽度太小，标签无法显示。
