Although I don't use Statistix to produce figures for publications, I'll often model my publication graphs on those quickly drawn with Statistix. I always tell students, 'before you run any statistical analyses, GRAPH your data,' and Statistix makes that really easy.
For me, its best features are easy access to graphical looks at the data and the 'Omit, select, restore' command. Puntos a favor: Statistix is my 'go to' program for most initial analyses of experiment data.
'Statistix (which I've used for may years) is great for EXPLORATORY data analyses.'
