display threshold
The display threshold below which nodes are ignored is entered in
percent. Calls whose inherent time makes up less than that percentage
are not shown in the method graph. If you raise the threshold, none
of the currently displayed nodes are hidden. If you lower the threshold,
nodes who do not have plus signs for expanding incoming and outgoing calls
may get them again.
To activate the threshold, you have to select the "Hide calls with less than ..."
check box.
This option allows you to trim down the call graph to the most important
parts.
