## Heap Walker Allocation View - Allocation Tree Map |

| The contents of the allocation tree map is an alternate visualization of the allocation tree. The tree map shows all call stacks as a set of nested rectangles. Please see the help on tree maps for more information.

| The heap walker will be able to display allocation information only for recorded objects, unrecorded objects are summed up in a top-level rectangle called `unrecorded objects`. See the memory section overview for further details.

| To add a selection step from this view you can select one or multiple allocation spots in the tree map and click the [Use selected] button above the tree map. A new object set will be created that contains all instances of classes and arrays allocated in the selected allocation spots. After your selection, the view helper dialog will assist you in choosing the appropriate view for the new object set.
