Hi julia
plenty examples of the icg plot environment are here

http://www.fz-juelich.de/icg/icg-1/idl_icglib/idl_source/idl _html/idl_work_idl_work.examples.category.htm

if you want a recent plotprepare.sav file let me know.

cheers

1) display your plot
2) overplot part of it, in a different color.

You have to find yourself what to overplot...
If you have hourly data, it's fairly easy, just subscript the original
data. If not, you will have to add points to your data set, at the
correct time. It's fairly easy to do...
