--call-graph::
|
||
|
|
Display callchains using type and min percent threshold.
|
||
|
|
type can be either:
|
||
|
|
- flat: single column, linear exposure of callchains.
|
||
|
|
- graph: use a graph tree, displaying absolute overhead rates.
|
||
|
|
- fractal: like graph, but displays relative rates. Each branch of
|
||
