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

The node description options control the amount of information that is presented in the description of the node. Show size bar If this option is checked, a size bar will be displayed whose length is proportional to the time that was contributed to the hot spot along the particular call path. Show time Show the total time that was spent in the method call. Show invocation count Show how many time the method was called in this particular call sequence. Always show fully qualified names If this option is not checked, class name are omitted in intra-class method calls which enhances the conciseness of the display. 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. Show average time values in brackets Show the total time spent in the hot spot divided by the number of hot spot invocations for each node in brackets. Is not displayed if the invocation count is 0, e.g. if an invocation has not completed yet or if sampling is chosen as the call tree collection method. This setting only applies to the back traces, the average time for the hot spot itself is always displayed in a separate column.

You can select a time scale mode for all displayed times: Automatic Depending on the time value, it's displayed in seconds, millseconds or microseconds, in such a way that 3 significant digits are retained. Seconds Millseconds Microseconds

The percentage calculation determines against what time span percentages are calculated. Absolute Percentage values show the contribution to the total recorded time. Relative Percentage values shows the contribution to the invoked method.
