is conceived as an instrument to assist physicists in the analysis
and presentation of their data. It provides interactive graphical presentation
and statistical or mathematical analysis, working on objects familiar to
physicists like histograms, event files (Ntuples), vectors, etc.

The CERN Program Library is a large collection of general purpose libraries
and modules maintained and offered in both source and object code form on the
CERN central computers. The two most popular applications based on CERNLIB are
PAW and GEANT 3.21.
The Nuclear Energy Agency (NEA) is a semi-autonomous body within the
Organisation for Economic Co-operation and Development (OECD), located in
the Paris area in France. The objective of the Agency is to assist its Member
countries in maintaining and further developing, through international
co-operation, the scientific, technological and legal bases required for a safe,
environmentally friendly and economical use of nuclear energy for peaceful

Qplotter is a C++ package to produce graphic representation of physics data
(such as histograms, scatter plots or curves) both on the screen and as
PostScript files. The same package could be used to produce simple 2D drawings
(e.g. test beam setup), but does not provide directly full 3D features such as
those of Open-Inventor/OpenGL. Qplotter is based on the very popular Qt
toolkit and can be freely distributed under the GPL scheme. Users in the
High Energy Physics community can think of Qplotter as a replacement of
packages such as HIGZ and HPLOT , the graphic subsystem of CERNLIB.
is the predecessor of Anaphe. I have contributed to the graphics side
of it in Iris Explorer and HEPInventor:
HEPInventor is a graphical library providing an interface between the
histogram data structures defined by the HTL package and graphics
