The allocation call tree view settings dialog is accessed by bringing the allocation call tree to front and choosing View->View Settings from JProfiler's main menu or clicking on the corresponding  toolbar button.

The view mode can be toggled with the cumulate allocations checkbox. This sets whether allocations should be cumulated to show all allocations below any method or not.

You can select a size scale mode for all displayed sizes: Automatic Depending on the size value, it's displayed in MB, kB or bytes, in such a way that 3 significant digits are retained. Megabytes (MB) Kilobytes (kB Bytes

The node description options control the amount of information that is presented in the description of each node. Show size bar If this option is checked, a size bar will be displayed whose length is proportional to the number of allocations including all descendant nodes and whose light-red part indicates the percentage of allocations in the current node. Always show fully qualified names If this option is not checked, class names are omitted in intra-class method calls which enhances the conciseness of the display. This option is only relevant for the "methods" aggregation level. Always show signature If this option is not checked, method signatures are shown only if two methods with the same name appear on the same level. This option is only relevant for the "methods" aggregation level.

The percentage calculation determines against what allocation numbers percentages are calculated. Absolute Percentage values show the contribution to the total number of allocations. Relative Percentage values show the contribution to the parent method. Whether the contribution is cumulated or not depends on the Cumulate allocations setting (see above).
