This is one of the better graphing/statistical packages out there on the mac. Their technical support is one of the best I have encountered. Tech support has even helped me to understand my statistical results. Although the graphic capabilities are quite good, they really need to allow more complicated ANOVAs (e.g. 3-way) in the program. In addition, there is not enough scriptability built into the program. But even so, it's probably the best graphics/statistical program on the Mac. Don't even consider SPSS, use this instead.
