If you are using graphs as a student of some kind - 'O' level, 'A' level or Business studies - then this is the package for you. Designed with students in mind it is really more than a simple graph drawing program. It can cope with most mathematical formulae including polynomial equations, quadratic equations, trigonometry and differential calculus, in fact almost anything that can be turned into a line graph can be used in this program.

The documentation provided is also a little out of the ordinary in that it is more of a text book than program documentation. Approximately one third of the 60 page booklet is a step by step "how to use it" section, the rest of the book being devoted to a discussion of the maths involved and giving example exercises for you to try. These range in difficulty from co-ordinates and scales to correlation and regression. There are even self assessment questions given so that you can check your knowledge as you go along. I wish other publishers of programs would take a look at this book and try to bring their documentation up to this standard.

The program itself is simple to use and comes with the function key strip that you need to operate it. The basis of the program is two curves, blue and red, which you can program independently to whatever function you desire. There is also the option of entering up to thirty pairs of data points and then either joining them or finding the line of best fit. You can modify the length of the scales and even measure the area under a curve, a very powerful feature. There are a number of features that would have made the package better, the ability to load and save data and the ability to screen dump the graphs being the most obvious. These do not detract however from a very well-organised and attractive package for anyone who likes to see graphs in action rather than read about them in their text books.
