HEPInventor

and

LHC++ workshop September 29, 1998 Olivier Couet CERN Geneva, Switzerland

HEPInventor implementation is based a list of graphics requirements listed in http://wwwinfo1.cern.ch.asd/lhc++/dat/HIReq.html.

Current version of HEPInventor provides:

Page layout definition (Zones)
1D representation: stairs plots, line plots, curve plots and errors plots.
2D histogram representations are available (box and color plots)
New class: HIPalette to defined the color palette used to draw 2D histograms with the option color.
Log scale axis
Grid on Axis
PostScript output
It is possible to print the histogram statistics.
HIData: New constructor for 2D matrices (with errors).
Axis title.
Some attributes definition: histogram color, Zone background color, text sizes, line width, line type etc... See the HEPInventor manual for the complete list.
New class HIComment to put comment in a zone in cm or zone coordinates.
Bug fixes and performances improvements. See: http://wwwinfo1.cern.ch/asd/lhc++/dat/hepinventor.html

The HistOOgramPlot module has been redesign in order to allow the plotting of several zones on the same page:

The Zone position can be specified
Several HistOOgramPlot modules can be connected on the same Render.
Axis titles can be drawn.
Postscript generation is now done via a specific module able to convert any Open Inventor geometry into a PostScript file

The Zone12 Group is composed as follow:
