I have used AXUM 4.0 for Windows for a couple of years now and find it to be powerful and flexible enough to create just about any kind of presentation-quality graph that I want. I am reasonably satisfied with it, but find that it is a little awkward at times. There seem to be some problems getting things to look right on the screen before printing them out, and the interface between AXUM and other Windows applications doesn't seem to work all the time, i.e., it's hard to cut and paste into other documents. I have also used PSI-Plot and Sigma Plot, but still prefer AXUM. I am anxious to upgrade to the latest version (4.1) when it is available.
