Yes, it works.. I thought it didn't work because the yrange for the
first group is way far away from that of the second group, that's why
the errors bars were too small that I thought the code didn't work.
Thank you for the help

I tried your plotting code after creating some simple variables and it
seems to plot OK (output on http://idlastro.gsfc.nasa.gov/ftp/landsman/idl.png
. --Wayne
a3 = indgen(5)
a0 = a3+1.2
a6 = replicate(0.5,5)
a4 = a6/1.5
a7 = a6/2.
a5 = a6
a1 = a0 /2.
