All of the plot labels generated by Ferret are automatically defined as symbols. This includes the title ($labtit), X and Y axis labels ($labx),($laby), as well as the position labels (latitude, longitude, depth, time), which are normally placed at the upper left on a plot (see "Labels" ). Sometimes it is desirable to change the location, size or fonts of these labels. The symbol facility makes it possible to do this in a way that is independent of the particular label strings or plot aspect ratio. See the demonstration script symbol_demo.jnl for an example.
