54 | -g [type,min]:: |
| 55 | --call-graph:: | |
| 56 | Display callchains using type and min percent threshold. | |
| 57 | type can be either: | |
| 58 | - flat: single column, linear exposure of callchains. | |
| 59 | - graph: use a graph tree, displaying absolute overhead rates. | |
| 60 | - fractal: like graph, but displays relative rates. Each branch of | |
| 61 | the tree is considered as a new profiled object. + | |
| 62 | Default: fractal,0.5. | |
