pie用dataset设置数据，tooltip模板显示值显示为对象而不是数字

It looks like the {c} reference in the formatter is referring to the whole object instead of the mapped value. In this case, it is e.g."{count:6,value: 251,name: "谷歌"}.

You can see the same behaviour here: https://ecomfe.github.io/echarts-examples/public/editor.html?c=dataset-default
if you add formatter: "{a} {b}: {c} ({d}%)"
to the tooltip area, you get the same results (here the whole line in the underlying array is displayed...)
