问题
在go tool pprof的Web输出中，虚线/点线代表什么？
我发现有人提到它可能代表内联函数，但没有官方参考资料。

In the web output of go tool pprof, what are the dashed/dotted lines?
I find some mention that it could represent inlined functions, but there's no canonical reference.

虚线表示节点通过另一个未在最终输出中呈现的节点进行连接。
请参阅 https://github.com/google/pprof/blob/master/internal/graph/dotgraph.go#L311
if e.residual {
attr = attr + ` style="dotted"`
}
而"residual"代表
// residual edges connect nodes that were connected through a
separate node, which has been removed from the report.
请参阅 https://github.com/google/pprof/blob/main/internal/graph/graph.go#L255-L257
英文:
Dotted lines represent nodes' connection through another node, which is not rendered in final output.
See https://github.com/google/pprof/blob/master/internal/graph/dotgraph.go#L311
if e.residual {
attr = attr + ` style="dotted"`
}
and residual stands for
> // residual edges connect nodes that were connected through a
> separate node, which has been removed from the report.
