Alan and Andrew, The difference in the latitude lines in example 19 has been there as long as pltransform and the Baltimore example 19 page have been included. The difference in dash positions occurs because plmeridians uses different rendering paths depending on whether it is given a coordinate transform function or not. If plmeridians receives a coordinate transformation function as it's first argument (C API) they it manually segments the latitude and longitude lines by repeatedly calling plline. If no coordinate transformation function is passed to plmeridians then it calls plpath to draw the latitude and longitude lines. plpath only calls plline once. I expect that this is where the difference in dash positions comes from. Hez ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.
