double click the x axis
maybe try editing the axis format when using the date column.
the min and max of the axis can be set here too
for a survival plot (Analyze>Reliability>Survival)
the grouping variable would be your animal group. (verify there are three distinct labels, no typos, or case changes, or leading/trailing spaces)
if some animals made it to day 100 when the study ended, then add a new colunm for censor. animals who survived are "1" and wuzzies are "0". Or use a single row for the fuzzies, and freq col for the number that survived.
the graph has a single x axis, so either date or day, but not sure how to get both without some wackyness.
