timeseries.ncl @ 567

Last change on this file since 567 was 566, checked in by heinze, 14 years ago
Formatting of all NCL scripts. Items of .ncl.config are re-sorted and xyc, xzc and yzc are no parameters any more. Parameters start_f_1/end_f_1 are renamed to start_f/end_f in profiles.ncl. Bugfix in cross_sections: enable vector plot if var is set explicitly. Deletion of NCL user guide because guide is no available online.
