The reason is that you're putting the text in with NORMAL coords set,
so it's relative to the window. Everything is in the same window, so
the normal coords don't change when you change plots. You'll need to
change to DATA coords, I think, or figure out some algorithm to define
your normal coord placement for each plot. Or do it by hand. :)
