Louis,

As far as I know, there is no easy way to produce box plots in GMT (I
assume you mean the plots frequently used in statistics, also knows as
box-and-whisker plots). You would need to write functions (in whatever
language you're scripting in -- perl might be good) that compute the
inter-quantile range, median, min and max, and then produce a box plot
using psxy.

Alternatively, you could use the open-source package "R"
(http://www.r-project.org/), which has a "boxplot" command.

Well, nice to learn something new. It appears designed for use with the
-JX projections. Is it possible to put box-and-whisker symbols on a
geographic map, where the dimensions of the box-and-whisker symbol are
determined by some other field? It appears that currently, the additional
columns are interpreted as latitude or longitude only.

I realize that this can be done in R using the "maps" package, but the
output isn't as nice as GMT's.

Thanks,
Bruce
