Graphing program, with various features.
GraphDraw allows the entry, and editing, of x,y values, and the data
may then be fit to
* best straight line (lin or log)
* best parabola
* cubic spline curve
* polynomial of order up to six.
The resulting graph may be printed via any standard RISC OS printer
driver, saved as a draw file, or exported as a MultiPlot file to
allow several graphs to be combined.
