PlotLib
PlotLib is Painter based package allowing to plot various data to graphs. The most interesting features are:
Configurable graphic smoothness level (basic, anti-aliasing or subpixel precision)
No GUI required, works even on machines without graphical environment (e.g. headless unix servers)
Offers wide variety of visual styles, both for lines and for symbols
Symbols can be easily added by simple inheritance
Includes a class for drawing a legend to a given graph
Hopefully easy to work with
If you need displaying graphs in GUI and/or user interaction, you will be probably interested in PlotCtrl.
