"I have used DeltaGraph since the early 1990's and most recently have downloaded DeltaGraph 5 for Mac. It works great. It has opened all my old 4.5 files perfectly as well as earlier ones. It even shows perfectly some of the special 'symbols' I created to show the censors on our survival curves in exactly the way our MD's like them."

" I can speak very well of DeltaGraph's ability to customize and precision match the exact look that a customer might want from any particular chart. This is something the statistical packages (StatView, JMP, SPSS, etc.) really can't accommodate. If one wants to use a graph in a slide presentation or a manuscript for publication and one is particular about how a graph should look, DeltaGraph is the only way to go, in my opinion. Now that I have DeltaGraph 5.0, I no longer need to start Classic up at all as I can do everything in OS 10."
