Plot Pilot is a freeware plotter for predefined functions or user definable relations formatted as tuples in a memo text.
The functions are evaluated by basic statistical routines. The graphics display is configurable.
Random and shuffle modules are also included, and basic audio output demo functions.
Applications are in teaching (for preparing materials or demonstrating with a mirror + VGA adapter, and for basic experiment support.
A manual is not included, but then we figure that if you download this kind of app you won't need one :-)
