Which jstat output item corresponds to jconsole's heap utilization chart?

Not being a JVM expert, I'm struggling to figure out which of the myriad of jstat's output items corresponds to the heap utilization % that is plotted in jconsole's memory usage chart. Anyone know or know something I could read to understand jstat's output?

Try http://java.sun.com/javase/6/docs/technotes/tools/share/jstat.html
I would guess that total heap usage in % is usage divided by capacity (times 100), for example:
((OU+EU+S0U+S1U)/(OC+EC+S0C+S1C)) * 100
or perhaps OGC etc. if you want numbers in percentage of the max capacity instead of the currently committed capacity.
