Bill, The OCaml bindings include a character_height function which (should?) return the character height in world coordinates: http://plplot.svn.sourceforge.net/viewvc/plplot/trunk/bindings/ocaml/plplot.ml?revision=11020&view=markup The function begins on line 611 and should be fairly self-explanatory. There is likely a simpler way to do this using internal PLplot functions, but this method allows you to stick to the public, documented API.
