New Revision: 27595
URL: http://svn.gna.org/viewcvs/relax?rev=27595&view=rev
Log:
Created XY-data functions for the plotting API of the relax library.
These are currently copies of the heads of the lib.plotting.grace functions
write_xy_data() and
write_xy_header(). These lib.plotting.api functions (write_xy_data() and
write_xy_header()) are set
up to use the grace functions.
