FreeHEP Plotter

The FreeHEP plotter will be based on the existing JAS Plotter (JASHist), but with changes to add new features requested by users, a plugin structure to make adding new plot types easier, and a more flexible data model to make attaching various different data types possible. The FreeHEP plotter will fully support displaying all AIDA plots types.

A partial list of design goals include:

• Support for histogram, XYPlot, ScatterPlot, 2D color maps, lego plots, contour plots ..
• Must be able to use any object as annotation or labels (arrows, latex, etc.)
• Must be able to build complex plots (multiple axes, shared axes, etc.)
• Extensible set of renderer
• Extensible set of data source interfaces
• Arbitrary map from axis to coordinate system (log, linear)
• Support 2D and 3D drawing (and in principle also inventor, opengl etc.)
• Output as postscript, SVG etc.
• Able to support strings (sorted?), dates, numeric axis
• Binned and non-binned axes, rebinning for binned axis
• Able to select a range in 1D and 2D plots for zooming, fitting in range, cuts etc
• Variable bin size
• Able to support legends, titles, annotations etc
• User able to directly interact with objects, move them around (including outside plot boundaries)
• Labels should resize to fit bounds
• Support for functions, directly setting initial values
• Arbitrary interactions between plot and data (rebinning, zooming etc.)
• Property pages and popup menus for customization
• External objects should be able to insert (or delete) items into property pages, popup menus
• Plot should be able to provide menus to external GUI
• Extensible using OO techniques (e.g. Specialized Axes)
• Saving/Restoring from XML
• Real time updating
• High performance (rapid updates)
