Tau RISC OS only is by far the nicest graphdrawing software Ive ever used, designed to give a publishablequality graph first time round. It aims to give the user complete control over how the graph will look, with defaults that give a really good graph immediately if you dont like the default settings, just change them till youre happy and save your own. You can save style files to speed up reprocessing of similar data sets. It will also do computations on your data, sort them, normalise them, fit best fit lines and curves through them, all via a huge spreadsheetlike area which lets the user drop in several datasets in various places. It works in colour useful for computer presentations and or line styles, all of which are adjustable. It permits you to bound the data area shown so that extreme values are blocked off; it will autoscale if you wish. The most recent additions are full 24bit colour on all drawing options and a quick way to change which columns are plotted.. The original version was written by Tim Birks, and I have in recent years taken over maintenance. Its here released in version 1.60, with Tims permission. Read the ReadMe and Help files inside the package for full details; an EasiWriterTechWriter manual is also provided, and also a pdf and html version of the manual.
