The button dynamically changes according to the selected layout. For example, if the chain layout is selected for the view, the button changes to show an option to choose a tree layout, and vice versa.
are typically more useful for the bottom-up view:
While tree layouts
are more natural for the top-down view:
Chain layout in the
pane is possible only if there is no branching AND when all values of data columns are the same for the parent and for the child.
Navigate Between Stacks
To view stacks for the selected program unit, estimate stack contribution, and identify the most performance-critical stack, use the
pane and click the next/previous
To view information on several stacks or program units, Ctrl-click to select these stacks or program units in the
pane shows the highest contributing stack from all the selected stacks, with the contribution calculated based on the sum of all selected stacks. All the stacks related to the selection are added to the tab and you can navigate to them using the next/previous
Note that though each stack in the
pane corresponds to a call stack provided in the
pane, the number of tree branches in the
grid does not necessarily equal the number of stacks in the
pane. Since the stack in the
pane is function-based and the stacks in the
pane are line-number-based, the number of stacks in these views may differ.
