The \emph{\faAlignJustify{}~Bottom-up call stack tree} pane is only available, if the memory events were collecting the call stack data (section~\ref{collectingcallstacks}). In this view you are presented with a tree of memory allocations, starting at the call stack entry point and going up to the allocation's pinpointed place. Each level of the tree is sorted according to the number of bytes allocated in given branch. The \emph{\faAlignJustify{}~Bottom-up call stack tree} pane is only available, if the memory events were collecting the call stack data (section~\ref{collectingcallstacks}). In this view you are presented with a tree of memory allocations, starting at the call stack entry point and going up to the allocation's pinpointed place. Each level of the tree is sorted according to the number of bytes allocated in given branch.
Each tree node consists of three elements: the function name, the source file location and the memory allocation data. The memory allocation data is either yellow \emph{inclusive} events count (including all the children), or the cyan \emph{exclusive} events count. There are two values that are counted: total memory size and number of allocations. Each tree node consists of three elements: the function name, the source file location and the memory allocation data. The memory allocation data is either yellow \emph{inclusive} events count (allocations performed by children), or the cyan \emph{exclusive} events count (allocations that took place in the node)\footnote{Due to the way call stacks work there is no possibility for an entry to have both inclusive and exclusive counts, in a properly instrumented program.}. There are two values that are counted: total memory size and number of allocations.
The \emph{Group by function name} option controls how tree nodes are grouped. If it is disabled, then the grouping is performed at a machine instruction level granularity. This may result in very verbose output, but the displayed source locations are precise. To make the tree more readable you may opt to perform grouping at the function name level, which will result in less valid source file locations, as multiple entries are collapsed into one.
Clicking the \RMB{}~right mouse button on the function name will open allocations list window (see section \ref{alloclist}), which list all the allocations included at the current call stack tree level. Clicking the \RMB{}~right mouse button on the source file location will open the source file view window (if applicable, see section~\ref{sourceview}). Clicking the \RMB{}~right mouse button on the function name will open allocations list window (see section \ref{alloclist}), which list all the allocations included at the current call stack tree level. Clicking the \RMB{}~right mouse button on the source file location will open the source file view window (if applicable, see section~\ref{sourceview}).
