The initial version of pllegend is now in PLplot trunk, revision 11165. This adds: - pllegend.c: The implementation, including a C-port of get_character_height which is not exposed in the public API - x04c.c: The first page has been updated to include a legend, and symbols have been added to one of the lines to help illustrate the pllegend API I need to run for now, but hopefully this is a good start. pllegend.c has a comment explaining each of the function arguments. pllegend allows basic line or symbol legends in its current state. Comments on the API are more than welcome!
