The time view shows a time-resolved histogram of object allocations. The bin size depends on the
zoom level.
This view can only be used if the "Record object allocation times" feature is activated on the "Memory Profiling" tab of the profiling settings dialog. Allocation times are only available for recorded objects. The number of unrecorded objects is displayed above the graph.
