GraphDraw allows the entry, and editing, of x,y values, and the data may then be fit to

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.

Version 3.00, released on 25th Aug 2015 is a completely new release, with GraphDraw having been totally rewritten from scratch and coded in C rather than Basic. Most of the features of the previous version have been retained. The biggest change is that you can now have several data sets active at the same time, and data set sizes are fully dynamic, so there is no restriction on the size of dataset that can be used.

The latest release is version 3.02, 12th Mar 2017

It has been tested successfully on the BeagleBoard, PandaBoard, iMX6, and IGEPv5, all running RISC OS 5.23. It should also run on RISC OS 3, but will require suitable toolbox modules and SharedCLib to be present.
