I think the "Simple Plot" macro here
http://rsb.info.nih.gov/ij/macros/ExamplePlots.txt will explain.
Center, left and right justified changes where the text is placed in
relation to the x coordinate in the addText function.  If you want the
text in the figure area, change the Y coordindate in the addText
function.
