In 2003, a -s flag was added to ministat to separate the
...
avg/median/stddev bars onto separate lines for readability if the
ranges overlapped. In 2005, ministat was extended to support more than
2 datasets, but the -s code was not updated. It will coredump if run
with -s and >2 sets.

Add support for more than two datasets. Currently limited to 7 though
...
the limit is only the number of meaningful graph symbols available.
Statistical comparison is performed between the first dataset and
any further datasets.

If your benchmarks are not significant at the 95% confidence level,
