Description:
CERNLIB data analysis suite - graphical library
CERNLIB is a suite of data analysis tools and libraries created for use in physics experiments, but also with applications to other fields such as the biological sciences. . The graflib library includes the HPLOT and DZDOC systems. HPLOT is a graphing facility intended to produce drawings and slides of histograms (and other data) of a quality suitable to talks and publications. DZDOC provides a method of viewing CERNLIB's ZEBRA data structures. . In order to compile and link programs against this library, you must also install the libgraflib1-dev package.
