The white panel on the left side of the stat-applet is the main control for
the plots on the right. This is the energy level pallet and is activated by
clicking in the window. Once a click is made an energy level will appear and
a line is plotted according to the selected function in the graph.
Selecting a Function is done by using the pull-down function menu in the the particular graph
window you would like to edit.
Depending on the mode of the energy level
panel you can add, edit, or delete any of the levels.
