GC panels with tabs to the left of this one contain
graphs which are most commonly used to visualize GC performance. This User
Defined panel was created to allow you to experiment with other combinations of
data gathered by -Xverbosegc
or -Xloggc
which you might find
useful.
By selecting variables for the X and Y axes from the pull-down
lists, you can plot the X-Y relationships for your GC data capture
file.
