Allocation Tree Comparison View Settings Dialog

  The allocation tree comparison view settings dialog is accessed by bringing any allocation tree comparison 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 differences should be calculated of the allocations cumulated for all descendant nodes or just for the current node.
  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 the call.
  • Show size bar
    If this option is checked, a size bar will be displayed whose length is proportional to the size difference of objects allocated in this node including all descendant nodes. Depending on the sort and display type view setting (see below), these differences are either absolute differences or percentages. Positive differences are painted in red, while negative differences are painted in green.
  • Always show fully qualified names
    If this option is not checked (default), class name are omitted in intra-class method calls which enhances the conciseness of the display.

    Only applicable if the aggregation level has been set to "methods".

  • 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.

    Only applicable if the aggregation level has been set to "methods".

  The size differences options determine how size differences are displayed and how sibling nodes are sorted.
  • Sort and display type
    The sort and display type can be one of
    • Sort by values
      The bar chart on each node displays absolute differences. Sibling nodes are sorted by absolute differences. Percentages are displayed in parentheses.
    • Sort by percentages
      The bar chart on each node displays percentages. Sibling nodes are sorted by absolute percentages. Absolute differences are displayed in parentheses.
  • Show zero difference values
    If this option is not checked, the call tree view does not display call stacks that have not changed between the first and the second snapshot.
  • Only show call stacks that appear in both snapshots
    If this option is not checked, the allocation tree comparison does not display call stacks that appear in only one of the compared snapshots.
